聚合物就地胶联调剖剂的研制及应用

The Development of Polymer In-Situ Gelling Modifier and Its Application

本文针对两口井的实际情况，研制了一种就地交联、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。

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.
