由于注水井管柱结垢,管柱油污等因素影响,在正常测试与打捞调配时,经常出现仪器遇阻或遇卡的情况。常规打捞调配工艺存在局限性,投捞成功率较低。同时有水嘴堵塞、漏失及因拔空网造成封隔器失效导致窜层等问题,无法达到分层配注的目的。在现有工艺基础上,通过改进和完善注水井投捞工艺,提高投捞成功率和注水合格率,减少作业量。 Due to the injection well tubular fouling, pipe oil and other factors, in the normal test and salvage deployment, the instrument often encounter resistance or card case. Conventional salvage deployment process has limitations, fishing success rate is low. At the same time there is a blockage of the water nozzle, a loss and a problem of channeling and the like caused by the failure of the packer due to the pull-out of the empty net, and can not achieve the purpose of stratification with note. On the basis of the existing technology, by improving and perfecting the fishing well fishing technology, the success rate of fishing and water injection can be improved, and the workload can be reduced.
