西部工区深井超深井段钻井提速技术

Drilling Speed-increasing Technology in Deep-well Deep Well Section of Western

由于西部工区储藏埋藏深,具有岩性复杂、钻遇地层压力体系多,下部地层老,可钻性差,易漏、易涌、易垮的诸多技术难点,通过优选钻头类型、优选先进提速工具,及时调整钻井参数,并针对技术难题,对西部工区钻井技术进行了研讨和实践,制定了一套可行的技术方案。

Due to the deep storage of the western part of the work area,it has many technical difficulties,such as the lithology complexity,the drilling pressure system,the lower part of the lower strata,the poor drillingability,the easy leakage,the easy and the easy collapse.By optimizing the bit type,Tools,timely adjustment of drilling parameters,and for technical problems,the western area of drilling technology research and practice,developed a set of feasible technical solutions.
