在油气井大修中 ,针对落物由于被卡死在套管内 ,采用常规套管内打捞存在施工周期长、技术难度大等问题 ,提出取套打捞技术以解决大修施工中存在的上述问题。该技术通过在中原油田文 72 - 10 5井、文 10 - 45井及文 13- 2 92井不同原因造成落物卡 ,通过取套打捞解卡 ,证实该技术是可行的 ,且具有推广应用价值 ,文中详细介绍该技术的特点
During the overhaul of oil and gas wells, aiming at the problem that the fallen objects were stuck in the casing due to being stuck in the casing and the construction period is long and the technical difficulty is large due to the salvage in the conventional casing, the salvage technology is proposed to solve the above problems existing in the overhaul construction. The technology causes the falling object card by different reasons in Wen-72-105 well, Wen-10-45 well and Wen-13--292 well of Central Plains Oilfield. It is proved that the technology is viable and has the advantages of popularization and application Value, the article details the characteristics of the technology
