研究了不同使用形式粘土堵剂的封堵能力(包括粘土分散体系,活化体系,和固化体系),得出适用的地层渗透率范围;针对胜坨油田矿场堵水调剖的实际,得出不同形式粘土堵剂适用的PI经验值范围,对今后的注水井调剖选用粘土类堵剂有指导作用。
The plugging capacity (including clay dispersion system, activation system, and curing system) of different types of clay plugging agents was studied, and the suitable range of formation permeability was obtained. According to the actual situation of water plugging and profile control in Shengtuo Oilfield, The application of different forms of clay plug PI empirical range of values for the future injection well profile control clay agent has a guiding role.
