Diffcult Point & Solution of Zhengan Shale Gas High Effective Horizontal Well Drilling

Jiliang YU


This article aims to provide technical support for the high-efficiency and high-quality horizontal drilling construction in Zhengan shale gas field. Based the analysis of the formation characteristics and drilling conditions in the Zhengan area, the technical issues of horizontal drilling improving in this area are explained, and based on speed-up and efficiency-increasing technologies such as the resigned high-efficiency PDC bit, high-torque&long-life motor, drilling parameter optimization, friction&torque monitoring, friction-reducing and torsion-reducing tools, near-bit geology steering technology, rotary steerable drilling technology and loss control and anti-collapse mud etc., solutions for the issues have been proposed. Through the application of related technologies, it is expected that improvements for the ROP of horizontal wells in the area and the drilling cycle will be made.
