| 摘 要： | RTTS封隔器因水力锚自身特有的防窜功能,在浅井测试及负压测试中具有广泛的应用。由于套管腐蚀变形或地层出砂等诸多因素的影响,测试结束后解封时,时有因水力锚无法正常回位而导致RTTS封隔器被卡的事故发生。从RTTS封隔器的工作原理出发,归纳提出RTTS封隔器卡钻后正确的解卡程序,对解决此类问题有一定的指导意义。

| Abstract: | Being particularly against leakage function of RTTS packer with hydraulic anchor is applied in shallow or under balance pressure extensively.Because of influence factors of tubing corrosion,deformation or producing formation san,for the hydraulic anchor not being right position to cause RTTS packer unstuck sometimes after well testing.From its operating theory,the unstuck procedure is summarized which has a guide sense for these kinds of problems. |
