泵送桥塞射孔技术作为页岩气水平井完井的关键配套技术之一,在应用中取得了良好的开发效果,但在施工过程中也出现了诸如桥塞座封失败、泵送过程中井下遇阻、桥塞座封后井下遇卡、上提过程中阻流管内电缆遇卡、桥塞座封后未丢手、泵送过程中射孔枪串落井等工程问题。针对施工过程中出现的问题,结合事故案例进行了原因分析,并制定了解决方案及预防措施。
As one of the key supporting technologies for completion of shale gas horizontal well, pumping perforation technology has achieved good development results in application. However, during the construction process, such as the failure of the plug seal, the pumping process In the underground encounter, after the bridge plug seat seal case met the card, on the mention of the process of resistance tube cable encounter card, seat plug after the plug is not thrown, pumping process perforating gun stringing wells and other engineering problems. In view of the problems occurred in the construction process, the causes were analyzed in combination with the accident cases, and the solutions and preventive measures were formulated.
