通过对牙哈油气田钻井技术难点的分析、井身结构的研究和试验,简化了井身结构设计,优选出了高效钻头系列和钻井参数配合,研究制定了适合牙哈地区长裸眼多套压力层系的钻井液方案,加快了钻井速度,缩短了钻井周期,并采用屏蔽暂堵技术有效保护了油气层。通过现场应用取得了良好的经济效益。

By analysing the difficult drilling problems of Yaha Oil & Gas Field and studying the well program , we simplify the well program design ,select the optimum bit type and drilling parameter , make the mud program for fitting local long opened hole and many set s of pressure profile formation , raise the drilling speed ,shorten the drilling cycle. We take the temporary jamming technology to protect the reservoir. We get the good profit by the practical application.
