In-house experiment of GL oil displacement agent applicability in shuanghe oilfield
-
Abstract
GL displacement agent can keep oil - water interfacial tension at ultralow status with oil sulfonate, as well as improve the fluid flowability of formations at the same time. Making a good analysis on oil displacement agent applicability is very important to prolong development period and stabilize crude oil output The experiment result shows the agent not only has good interfacial tension, as well as lower oil viscosity, but also has good compatibility with fluid and lithology of formation, which can increase the recovery of remaining oil about 17. 87%.
