摘要: 本文针对两口井的实际情况,研制了-种就地交联、且初凝时间可调的调剖剂。并通过室内岩心实验对其性能进行了系统评价,提出了岩心中成胶时间的测定方法。现场调剖施工取得了良好结果,调割后对应油井产量增加,注水井的吸水剖面得到明显改善。

Abstract:

In the light of the practical conditions of the two wells, an injection profile medifier bas been developed, which has the properties of in situ gelation and adjustable gelation time. A system evaluation has been given to its properties in laboratory through core flooding experiment, and the measurement of gelation time in porous media has been proposed. A good result has been achieved in the in situ modification operation. Thus the oil production increased and the injectivity profiles of the injection wells greatly improved after the modification.

Key words: Water injection well, Injectivity profile, Injectivity index, Permeability, Profile control, Polymer
