Casing pipe lifting pipe column and rotary unsealing mechanism and method

The invention discloses a casing pipe lifting tubular column and a rotary unblocking mechanism and method. The casing pipe lifting tubular column comprises a packer connected to a fixed-length oil pipe, a tubular oil well pump and a liquid inlet screen pipe, the tubular oil well pump is located above the liquid inlet screen pipe, and a plunger in the tubular oil well pump is connected with a hollow polish rod above the fixed-length oil pipe through a fixed-length pull rod; the device further comprises a casing pumping-assisting centralizer. The sleeve pumping-assisting centralizer is connected to the hollow polish rod and used for centralizing and pumping-assisting in the sleeve above the fixed-length oil pipe. The problems that in the prior art, the descending resistance is large, and the lifting efficiency is affected are solved, and the technical characteristics of rapid operation, liquid extraction, efficiency improvement and the like are achieved. 本发明公开了一种套管举升管柱及旋转解封机构及方法，包括连接在定长油管上的封隔器、管式抽油泵、进液筛管，所述管式抽油
