采出液配制二元复合体系可行性实验研究
Experimental study on feasibility of preparing surfactant/polymer flooding system with produced fluid
摘要
Abstract
A huge amount of fluids is produced during surfactant/polymer flooding in the Jinl6 block of Liaohe oilfield; meanwhile it is required to inject water into the reservoir to maintain reservoir pressure. Bench scale displacement test has been carried out to simulate the produced fluids after surfactant/polymer flooding for this block, to measure the interfacial tension, viscosity stability and rheological property of surfactant/polymer system prepared with produced fluid, and to study the feasibility of the prepared system. The results indicate that the polymer amount used for preparing surfactant/polymer system with produced fluid is always less than that used for preparing the system of same viscosity with treated produced waste water. The surfactant/polymer system prepared with produced fluid has interfacial tension up to 10~3mN/m and has good viscosity stability and viscoelasticity, therefore it is feasible to prepare surfactant/polymer system with produced fluid.关键词
