中文摘要: |
为解决渝东南地区页岩气钻井过程中井漏严重、机械钻速慢等问题,在Y2井的上部大冶组至水车坪组地层进行了空气钻井试验。试验结果表明空气钻井技术治漏、提速效果显著,缩短了钻井周期,井身质量较好。该技术的成功应用,表明在渝东南地区上部地层可以推广使用空气钻井技术。 |
英文摘要: |
In order to solve the problems of serious leakage and slow drilling speed in shale gas drilling process in Southeast Chongqing, air drilling tests were carried out in the upper part of Y2 well, from the Daye formation to the ShuiChePing formation. The test results show that the air drilling technology has a significant effect on leakage and speed increase, shortens the drilling cycle and acquiring wellbore quality. The successful application of the technology shows that the air drilling technology can be used in the upper strata of the Southeast Chongqing. |
