How to use horizontal directional drill

First, drilling is performed vertically through the drilling platform until the target rock formation is reached. Horizontal directional drilling tools are then used to control the wellbore orientation and start horizontal drilling. This drilling tool can control the direction and drilling degree of the drill bit through key technologies to ensure correct control of the wellbore.

Secondly, horizontal directional drilling also requires well wall stabilization and support during the drilling process. Strengthening measures are generally adopted, such as using special pipes to reinforce the wellbore or adding drilling fluid during the drilling process, to ensure the stability of the wellbore to avoid collapse or deformation of the wellbore and maintain the drilling process.

Not only that, horizontal directional drilling also requires accurate measurement and positioning. During the drilling process, modern drilling tools and measurement technology need to be used to accurately read the direction and depth of the wellbore to connect various control points and avoid excessive deviations in the wellbore.
In addition, special attention needs to be paid to the fact that horizontal directional drilling technology has some difficulties in the drilling process, such as wellbore torsional resistance, formation complexity, drilling fluid sliding and pressure loss, etc., which all require drillers to be careful during the actual operation. Think carefully and solve it.
