Description

Rig ground anchor based on sand geology water network area construction

Technical Field

The utility model relates to a rig construction technical field especially relates to a rig ground anchor device based on sand geology water network area construction.

Background

In order to facilitate the comprehensive utilization of oil and gas, a transportation pipeline for transporting the oil and gas is required to be laid between an oil and gas production area and an oil and gas consumption area. During the laying process of the transportation pipeline, obstacles such as rivers, roads and the like may be encountered, and at this time, in order to avoid the situation that the cost is too high due to the detour of the line, the crossing construction is generally selected, that is, the pipeline is laid through from the lower part of the rivers, the roads and the like, and the crossing construction is generally carried out by adopting a directional drilling method.

Before the drilling machine works, the ground anchor mechanism needs to be utilized to stabilize the drilling machine, whether the ground anchor mechanism is stable or not is reliable, and the ground anchor mechanism plays an important role in accurate positioning of the guide drill bit, successful laying of the reaming back dragging pipeline and safe production. The condition that the construction fails due to the fact that the water content of sandy soil in the sandy water network zone is high and the bearing capacity is poor and the loosening of the ground anchor is easy to cause the collapse and blockage of a hole after construction is stopped is obviously caused, so that the traditional ground anchor mechanism can obviously not meet the requirements of the construction of the existing drilling machine.
