摘要
Abstract
The directional drilling trajectory control technology in coalbed methane drilling construction plays a key role in complex geological conditions.In this paper,taking MB05-B6-26L-02 well as an ex-ample,problems of wellbore leakage and collapse that occur during construction have been studied.The factors that affect trajectory stability,such as geological characteristics,equipment accuracy and mud per-formance have been analyzed.Improvement of mud treatment technology and optimization of the use of di-rectional instruments have been proposed to improve the accuracy and stability of trajectory control.Through simulation experiments,it has been verified that the use of optimized technology can improve the construction efficiency of coalbed methane drilling,reduce the failure rate during construction,and ensure the stability of wellbore trajectory.关键词
