摘要
Abstract
in the process of coalbed methane drilling,if we are affected by factors such as formation stress, construction conditions and rock properties,it is easy to cause accidents such as sticking and borehole collapse. By applying drilling fluid performance and maintenance technology,we can reduce the probability of coal seam collapse. In this regard, this article first carries on the introduction of the CBM well borehole instability mechanism,and then by way of experimental analysis on properties,anti sloughing drilling fluid technology application and effect are reviewed,in order to provide reference for wellbore stability work.关键词
