腰深1井位于吉林省前郭县查干花镇后佟岭窝堡,为松辽盆地南部长岭断陷腰英台深层构造上的一口重要开发井,关井最高油压31MPa。因井下安全阀故障停产,地面无法正常开启,以及因压井压死地层无法正常替喷,施工中先后两次采用连续油管进行非常规修井——连续油管热冲洗、气举作业,成功打开井下安全阀,卸掉井下安全阀,换管柱高效恢复气井生产,保证了施工的安全,确保了施工的成功。
The Yaoanshen 1 well is located at Tonglingwo Fort, Chaganhua Town, Qian Guo County, Jilin Province. It is an important development well on the Yaoyingtai deep structure in the Changling Fault Depression in the southern Songliao Basin. The maximum oil pressure in the well is 31MPa. Due to downhole safety valve failure shutdown, the ground can not be normally opened, as well as the formation of wells can not be killed due to the pressure well injection, the construction has twice using coiled tubing for unconventional workover - coiled tubing thermal rinse, gas lifting operations, the successful opening Underground safety valve, remove the safety valve underground, efficient replacement of gas wells column production to ensure the safety of construction to ensure the success of the construction.
