Requirements For Trajectory Control Of Directional Drilling Rig in Engineering

Directional drilling rig plays a great role in pipe laying equipment and is an important equipment in trenchless engineering. Although trenchless engineering is machine construction, we need to pay attention to many details. Do you know the requirements for trajectory control of directional drilling rig in any project? Here are some materials to share with you, hoping to help you.

Here we first introduce the guiding track of trenchless engineering, which can be divided into four types: straight line segment, curve segment, degree segment and straight line segment, which we should design before the construction of the project. Although we have designed it in advance, we should also stop controlling the practice track of the drilling rig

Only stopping the trajectory design without stopping the trajectory control is equal to no design. The trajectory control Ming Ji drilling trajectory is consistent with the design trajectory, and the guidance accuracy is greatly reduced by experience alone. Once there is a large deviation between the ideal drilling trajectory and the design trajectory, it is difficult to stop the deviation correction drilling. Because the drill bit is easy to slide into the old hole, repeated deviation correction will form a rotten hole. Therefore, the accurate control of the drilling practice trajectory is needed.

Modern trenchless engineering pipe laying technology refers to the new construction technology of laying, changing or repairing all kinds of open pipelines without digging grooves on the surface by means of geotechnical guidance, directional drilling and so on. This technology has significant social and economic benefits, especially in some areas where excavation operations cannot be carried out, such as crossing roads, railways, buildings, rivers, historic sites maintenance areas, downtown areas, crops and vegetation maintenance areas. The technology has been used in gas, telecommunications and power engineering departments.

1. Trenchless construction can not block the traffic and destroy the roads and vegetation, so it can prevent the interference of residents' life and traffic caused by excavation construction, as well as the damage to the foundation of environmental buildings, without pollution and noise.

2. The open work quantity of excavation construction is reduced, and the trouble of open water operation is prevented. It accelerates the construction progress of the trenchless project, shortens the construction period, has a small working surface, can control the direction of pipe laying, has high construction accuracy, and has low comprehensive construction cost. It brings a technical reaction to the open pipeline construction.

3. Under the condition that the excavation construction is difficult to stop or basically not allowed to stop, the use of trenchless engineering can make the pipeline construction possible, and the pipeline can be designed to pass through the place with economic and reasonable construction quantities.

4. It has better economic and social benefits, especially when the buried depth and pipe diameter are larger, the benefits are more obvious
