选择性支撑剂性能评价及在低渗透裂缝性油藏的应用

随着低渗透油田进入中高含水开发期,许多油田面临措施后高含水的问题,如何有效控制油井措施(压裂、防砂、堵水)后含水的上升,提高油井产量,成为油田开发的一个工作难点。该文介绍了一种多功能选择性支撑剂在低渗透储层的应用。这种支撑剂在充分研究分析目前支撑剂等产品性能基础上,结合界面张力理论,运用新的单分子膜强疏水界面处理技术开发出来。它既降低了油的流动阻力又可提高水的流动阻力,从而达到增油疏水的效果,进而实现压裂、防砂、堵水多功能化,真正做到了"一砂多能"。

Performance evaluation of selective proppant and its application in low-permeability fractured reservoir

When low-permeability reservoirs come into the stage of development with middle or high water cut,many of them have to face the problem of high water cut after operations.As a result,it is a great challenge for oilfield development to effectively control water cut after operations(such as fracturing,sand control,water plugging) and increase oil production.This paper introduced the application of a multifunctional proppant in low-permeability reservoir.Through research and analysis of the performance of curr...
