随着油田开发时间的延长 ,油水井井下套管的损坏将越来越严重 ,套管故障井将越来越多。为了恢复套损井生产 ,将套管损坏所造成的损失降到最低 ,在配套波纹管补贴、水动力补贴、爆炸补贴等专门修套技术的基础上 ,通过认真调查研究 ,又配套了操作方便简单、适用套管损坏类型广的自动力套管补贴加固技术 ,使各种套管变形、套管断错 (错开没有位移或位移量不大时 )、套管破裂、误射孔井段封堵、已射开水层封堵等修井作业的难度进一步降低 ,从而进一步提高了修复井综合开发经济效益。
With the development time of the oil field extended, the damage of casing of oil and water wells will be more and more serious, casing failure wells will be more and more. In order to recover casing damage production, the losses caused by casing damage are minimized. On the basis of specialized repair sleeve technology such as supporting of bellows, hydrodynamic subsidy and explosion subsidy, etc., through careful investigation and study, it is also convenient for operation Simple, suitable for casing damage A wide range of types of automatic force casing reinforcement technology, so that a variety of casing deformation, casing error (not misplaced or displacement is not large), casing rupture, mistaken hole section seal Blocking, water injection has been blocked and other workover work more difficult to further reduce the cost, thereby further improving the economic recovery of comprehensive development of wells.
