| 中文摘要: |
| 在伊拉克M油田中，由于地层能量较为充足，油气含量较高，且油井均为自喷生产，后期动管柱可能性较小，因此在老井完井管柱中均下入永久式封隔器。中海油接手作业者以后，下入T95材质的永久式封隔器，进行生产。随着开采时间的延长，部分油井不能自喷生产或者产量递减严重，不能满足开采要求，因此需要进行修井作业，而对于永久式封隔器的处理成为必不可少的作业步骤。本文通过对比不同材质的封隔器的处理方法，得出处理高强度材质永久式封隔器处理技术，为其他油田类似永久式封隔器的处理，提供了方法和经验。 |
| 英文摘要: |
| In Iraq M oilfield, due to sufficient formation energy and higher oil&gas ratio, all the well flow naturally and the chance of POOH the string is low, so it’s common to run the permanent packer in the original well for production. As CNOOC take the operator, continue to run T95 permanent packer for production. With the production extension, some wells can’t produce naturally or the decline of production can’t meet the production requirement, which need workover operation and the processing of permanent packer become an essential operation step. According to this paper, comparing the treatment measures among the different material permanent packer, it’s concluded advanced technology method for retrieving the high strength material permanent packer, which provide the experience and method for similar permanent packer treatment in other oilfield. |
