Requirements for directional drilling rig trajectory control in trenchless engineering

Directional drilling rigs play a great role in pipeline laying construction. They are important equipment in trenchless engineering. Although trenchless engineering is all machine construction, we need to pay attention to many details. Now let's introduce: trenchless engineering Necessity of Drilling Rig Track Control in Excavation Engineering

Here we first introduce the guide trajectory of the trenchless project, which can be divided into four types: straight line segment, curved segment, horizontal segment and straight line segment, which we must first design before the project construction. Although we have designed in advance Good, but also control the actual trajectory of the rig.

Only carrying out trajectory design without carrying out trajectory control is equivalent to no design. The trajectory control ensures that the actual drilling trajectory conforms to the designed trajectory, and the steering accuracy is greatly reduced based on experience alone. Correction drilling is very difficult, because the drill bit is easy to slip into the old hole, and repeated correction will cause rotten holes. Therefore, accurate control of the actual drilling trajectory is necessary.
