摘　　要：磁性粘弹体封隔器的主要密封件是被永磁体吸附在油套环形空间的磁性粘弹物质，能可靠地封隔套管腐蚀变形井的油套环形空间。室内试验结果表明，这种封隔器坐封合格率和解封合格率均为100％，性能完全达到了设计要求。在矿场试验中，采用这种封隔器取得了油井增油降水，减少出砂和延长免修期的良好效果。The main sealing element of a magnetic viscoelastic packer is the magnetic viscoelastic material absorbed in the tubing-casing annulus by a permanent magnet. The packer can be used for the sealing of the tubing-casing annulus of the wells with corroded and deformed casing string. The result of the laboratory test shows that the operation performance of the packer accords with the design requirements. And good effect has been achieved in the appplication of the packer.
