山西沁水煤层气多分支水平井的显著特点是水平位移大,分支较多,从而导致钻柱在井眼内的摩阻和扭矩很大,利用模拟软件将已设计的井和已选定的钻具组合一起进行分析,得出一套合理的钻井方案,降低钻柱的扭矩和摩阻,从而避免井下事故的发生。本文针对郑试平6H井煤层气多分支水平井进行分析研究。 The remarkable characteristic of multi-branch horizontal well in Qinshui coalbed methane in Shanxi Province is that it has large horizontal displacement and many branches, which leads to large friction and torque in the wellbore. Using simulation software, the designed well and the selected well A combination of drilling tools to analyze, come to a reasonable drilling program to reduce the drill string torque and friction, thereby avoiding the occurrence of underground accidents. In this paper, we analyze and study the CBM multi-branch horizontal well in Zhengping-6H well.
