Almost 50 years ago (60s), a new technology was developed for the first time, named GNB. And immediately became in demand such work. Horizontally directional drilling instantly became popular in the United States. Americans stopped:
- Open asphalt;
- Disassemble
- Change traffic streams to lay communication.
In such conditions, Americans, and then all the others, began to use the GNB method. At the construction site, which uses the GNB method, if you exclude utility workers, three specialists operator must work, mandatory. They must be present on:
- Mixing installation.
The technology of the method consists of three stages, and on each of them requires an operator of the GNB. All well data is displayed on the employee's monitor, whose work is performed on the installation of the GNB. Thanks to such information, the operator is able to monitor the passage of the bera and accurately monitor its work by setting the depth of drilling and the right direction.
As you can see, the operator of the GNB, the training of which is carried out in various specialized training centers, is an important link when using the horizontal drilling method.
Given the need (it is constantly increasing) a modern construction complex in professional personnel, many companies began to open centers where personnel training is being trained, which will work in the field of GNB.
Perhaps the best center is located in the city of Kazan. For many years, specialists of the GNB complexes have been representing different regions of the Russian Federation (there are even representatives of foreign countries), are collected here to improve their qualifications. And training is conducted by the International Association of Specialists (MAC) of the GNB.
The SNB driver is obliged to control the installation, carry out the mounting of the drill tool, perform small repair and maintain the complex. In addition, its official duties include servicing the adjacent construction site, as well as loading (unloading) work (for example, pipes, bentonite).
The GNB wizard organizes all the necessary work on the GNB to the delivery of the object. He must:
- Lead the work of the brigade;
- Understand the project documentation;
- Coordinate engineering communications;
- Keep reporting documentation.
A specialist who performs the duties of the master is obliged to know the drilling rigs, to understand the repair of equipment and its service, be able to work with location equipment. In a word, he must have practical skills to organize work and its leadership.
An engineer of the SNB is engaged in the design of closed transitions, performs their shooting and performs support for the construction of transitions under:
- Gas pipeline and water supply;
- Sewage;
- Electrocabel.
The duties of this specialist include:
- Control of work at objects;
- Control of the supply of equipment and the necessary materials;
- creating ID (executive documentation) and its coordination with exploiting organizations;
- Communication facility.
As you can see to become a really cool specialist, you must study the GNB.

Horizontal directional drilling was invented more than 50 years ago in the United States. The insightful American engineers quickly realized that for this technology the future. Gradually, the GNB method began to be applied, with a trenchless laying of underground engineering communications, in different countries. USA, Europe, Canada, China and only in the last decade This method has been distributed in Russia. This is a simple explanation, this technology has a number of indisputable advantages: eliminates damage to the surface of the Earth when laying pipes, increase the speed of work and reduce costs. However, with an increase in the popularity of the method in our country, a serious problem arose - a sharp shortage of good specialists in this area. Vocational training of operators, engineers, masters and machinists has become relevant. However, places where qualified preparation of such personnel is extremely small.
GNB Learning Services
Our company "CDM" has been successfully operating in the Russian burdard market since 2005. We some of the first began to apply GNB technology when laying pipelines in Russia. Soon the company opened a unique training center for training SNBs of specialists. The main advantage is our advantage - we know the whole process of horizontal drilling from the inside not only in theory, but also in practice. And we will gladly pass this experience with students. Practical classes are held on real objects of our customers.
Educational work is carried out under the Protectorator of the International Association of Horizontal Directional Drilling Specialists (MAC GNB) according to the relevant license. For several years of work, our educational center has passed qualified training more than one thousand GNB operators from different CIS countries. At the moment, many specialists who have a diploma of the training center carry out work in serious Russian and foreign companies.
Training operator SNB.
OPB operator is a key specialist when performing horizontal drilling. From the experience and qualifications of the operator, it largely depends on the quality of the end result of drilling. At the construction site, during the execution of the GNB, there must be at least three operators: on the drilling rig, locator and mixing system.
The operator is the main link in drilling, it is assigned a number of important duties:
- control over the technological process of horizontal directional drilling;
- calculation of the optimal trajectory of the drilling head;
- the correct setting of the geolocation system frequency;
- determining the depth of drilling;
- the ability to eliminate malfunctions in the installation of the installation GNB.
Internet resources search for employees are overdated by ads for searching for the SNB operators. Such work is paid well (average Z.P. is 60-70 thousand rubles). A qualified operator at the moment of gold weight. In our training center, the main emphasis is placed precisely on the training of GNB operators. Most of the course is built in practice. Future operators get knowledge directly at construction sites, managing real settings (XCMG or Vermeer). Due to this, after passing courses, experts are ready to immediately begin to fulfill the responsibilities of the OBB operator. At the moment, many regional recruiting agencies cooperate with us and employed employment contracts are concluded, even before the end of the educational process.
TRAINING MACHINE SNB.
The role of the driver can also be underestimated, it depends on the state of the installation of the installation and other equipment that performs auxiliary functions during drilling work. In addition, it carries out the installation of all drilling equipment and controls the progress of the preparatory work.
In our center the training of this specialty is carried out. Future machinists receive all the necessary knowledge to fulfill their duties. There are long-term practices from experienced machinists of our company, they can be directly involved in drilling in real construction sites.
Training engineer of GNB.
The engineer is the brain of the workflow. Its shoulders are the design of horizontal drilling on the laying of engineering communications and the construction of underground transitions. It carries out all the necessary calculations, constitutes executive documentation, develops and coordinates the project of drilling work. He is also responsible for the delivery of the facility. Training of the SNB engineers in our center is somewhat different from other courses, as there are many nuances and features.
At the end of the training and the results of the summary exams, all students receive appropriate diplomas. It is worth saying that the diplomas of our training center are of serious weight in this industry.
In the last article, we talked about the history of the GNB method and mentioned that at the beginning of the 80s, when the method was only beginning to develop, there were no location tracking systems, and had to drill "for good luck".
Today things are different. In the United States and European countries, the volume of the horizontal drilling market is more than 95% of the entire gasket market. In Russia, the method of horizontally directional drilling is under development. The GNB technology is approved and recommended by the Gosstroke of the Russian Federation for the construction of underground communications. According to 2013 in the Russian Federation, the volume of works performed by the method of horizontally directional drilling amounted to:
- in housing and communal services and construction - 34%,
- electric power - 30%,
- laying engineering communications - 23%,
- gasket pipes for oil and gas transportation - 18%,
- other application is 5%.
No installation of horizontal drilling is done without an accurate location system, which allows you to track the drilling process "from" and "to". However, some customers still have concerns about the reliability of the method, since direct visual contact with drilling equipment in the ground is not. In this article, we describe the algorithm for the operation of location systems with horizontal directional drilling to dispel concerns.
Locations are created in the late 80s in order to control the drilling process, today they are most convenient for operation, and perform the following functions:
- tracking location and drilling head movements;
- tracking the temperature of the drill head;
- determination of the required drilling head grounding depth.
Each location system consists of three key elements:
- The probe is the emitter built into the drill head. It gives the signals that the locator takes. The probe fixes the position of the drilling head in the ground - depth, angle of inclination and angle of rotation, as well as its temperature and other parameters.
- The receiver is the PNB locator, processes the information incoming from the probe, converts to the readable format, and displays the display. The location operator (local locator) accompanies the drillhead on the entire path and sees the information on the locator screen. The drilling machine operator sees the same information on the repeater screen, so the information is broadcast for two screens: the location operator (locator) and the operator of the drilling rig.
- Radiocoupling is organized between the locator and the operator of the installation of the SNB. It is the operator of a local radio installation that gives commands to the OBB operator. The SNB operator in turn performs its commands and adjusts the movement of the drilling tool, the angle of inclination and angle of rotation, if necessary. He also sees all changes in the actual position of the drilling head on the repeater screen.
Thus, the probe mounted in the drill head transmits information about its location, also fixes the depth, angle of inclination and angle of rotation, temperature and other parameters. The signal is received by the ground locator, after which the information is converted to the readable format and is transmitted to two displays: the receiver's display and repeater screen.
The location operator accompanies the drill head and sees information on the locator screen. The drilling machine operator sees the same information on the repeater screen. Between the locator and the operator of the SNB installation, radio communication is organized by means of radiation. It is the local locator that manages the process, it submits commands to the OBB operator, about which actions it should perform (to what angle to turn the drill head, to drill with rotation or crushing the rods, etc.) it promptly adjusts the drilling head direction according to the directions. In case of deviation of the head from the project direction, the OPB operator changes the trajectory of the drill movement, bypassing underground obstacles to avoid collisions with underground communications: pipelines -Gazo, -DO and pipelines, manifolds, telephone lines, etc. The drilling operation of the pilot well is completed with the output Drilling head in the installed place.
With the advent of location systems, the drilling process became fully controlled and secure. In this article, we talked about the sequence of the location system. We hope that now you can more clearly imagine all stages of drilling tracking. Note that the tracking of the drilling head when laying the communication is not the only geolocation process in the practice of the GNB: the installation of the thermal imager is used in the previous stages of the work of the GNB, for example, at the stage of studying soil and geodesic work.
To date, there are at least a dozen location systems of different firms for GNBs, each of them has both advantages and disadvantages. If you want to see an article in which we are comparable to receiver devices, leave an application in the comments on Google+ And it will appear in the blog!
Laying communications by horizontal directional drilling (GNB) conquers increasing popularity. At the construction site, the implementation of such works is engaged in the GNB Brigade, and the vacancies in this area of \u200b\u200bemployment helps to fully reveal their professional potential. Failure of work, relevant qualifications, the possibility of professional and career growth - factors attracting a large number of candidates for such vacancies of the SNB, as an operator, local engineer, driver, engineer, etc.
The presence of secondary special education is necessary because the work of the SNB provides for the use of technologies requiring knowledge about their competent application.
Requirements for the applicant for the job of the "GNB Installation Operator"
There should be 3 operators on the construction site, each of which is responsible for different stages of drilling:
- installation operator, shovel guiding;
- the locator that tracks the passage of the boracy using the location system;
- the operator of the mixing installation is responsible for a bentonite solution, which prevents overheating of the shovel of the borax and contributes to the softening of the soil.
One of the main roles on the construction site performs the OBB operator, the opening accompany these requirements:
- Knowledge of horizontal drilling technology.
- Skills in maintenance of technical equipment.
- Additional requirements may be the ability to welding PND pipes and work experience at least 1 year.
For a trenchless gasket, expensive installations are used, so the management is impossible without appropriate qualifications. Some firms organize training and take newcomers in this industry.
Such a step can be explained by the fact that the technical equipment in enterprises is different, and the model of the drilling rig may require specific knowledge to competently handling equipment. On the territory of Russia, both foreign installations are used (Vermeer, Xcmd, Ditch Witch) and domestic ("Svyatovit", "Enerprom" and others).
The duties of the operator include maintenance of drilling rigs, the preparation of equipment and carrying out the work of the GNB (soil drilling, the drainage of cases), control of the depth and correct direction of the bora.
Considering that drilling technology implies employment in a brigade, employers include loading and unloading complex, cleaning construction and installation work.
In Russia, wages specified in the ads on the vacancy "Operator of the GNB" may differ for several tens of thousand rubles. The difference in pay for labor is related to the fact that the different goal of the drilling (gasket of cable of power grid, water supply or gas pipeline pipes) implies different volumes of work and the complexity of their implementation.
The rate of the rate depends on the region in which the company is located and from the equipment used by it.
Requirements for the applicant for the vacancy "Locator"
A GNB locator, a vacancy of which can also wear the name "Location system operator", must comply with such requirements:
- Knowledge of the location system.
- Reading project documentation, drawings.
- Availability of a driver's license category V.
- Welding and installation of PND pipes.
Its obligations include control of the entire installation process. The higher the remuneration of labor, the more the requirements put forward to the applicant. It must lay and control the drilling path, preventing damage to other communications.
The operator is at the disposal of the operator is a special location system, which is a probe fixed on the drill head, and a special device that provides synchronization. The device is equipped with a display with control buttons. With the help of the probe, the information is recorded where the drilling line is directed, what the rumble of the drilling head turns and what is the temperature of the installation of the GNB.
The data obtained by the locator allows you to drill a well using the minimum time and material costs.
New location systems are arranged so as to spend the minimum amount of training time. This explains why firms open new training centers and ready to take newcomers.
Error in calculations or inattention When performing location will lead to losses and will question the feasibility of applying a trenchless technology. Therefore, the requirements for the vacancy "Locator" remain high.
Other vacancies SNB.
Drilling involves the presence of a number of workers in the brigade. Along with the operators of the drilling and mixing unit and the locator, there are vacancies of the Machinist GNB, Masters, Engineer
The driver is responsible for managing the installation. Also in his obligations include installation of equipment, repair and maintenance of the instrument. The zone for which he responds is also the territory of the construction site, loading and unloading of pipes and bentonite components.
The Wizard vacancy involves the skills of organizing all types of drilling work, including the delivery of the object. It must understand the design of installations and locators, the specifics of project documentation, maintain and repair the equipment.
The master is headed by a brigade, conducts reporting documentation and coordinates engineering communications. His work requires skills in organizing a team and experience in managing the works and the implementation of the drilling plan.
Engineer is engaged in the design of closed transitions. His responsibilities include:
- shooting and maintenance of drilling work under sewage communications, water and gas pipelines, electrocabel, etc.;
- control of work at the SNB object;
- solving issues of supply of technical equipment and materials;
- drawing up executive documentation for coordination with representatives of organizations operating the object;
