油田注聚合物驱井堵塞机理研究进展

Research Progress on Blockage Mechanism of Polymer Flooding Wells in Oilfield

聚合物驱油是提高原油采收率的主要手段并得到广泛应用,但注聚井堵塞现象严重。为解决注聚合物井堵塞问题,国内外专家对注聚井堵塞机理进行研究。本文从多角度对注聚井堵塞机理进行分析,以期丰富堵塞机理研究体系,提高聚合物驱油效果。

Polymer flooding is the main method to improve oil recovery which is widely used,but the blockage of polymer injection wells are obvious.In order to solve the blockage problem of polymer flooding,experts at home and abroad have studied the blockage mechanism of polymer flooding.In this paper,the causes of blockage in polymer injection wells are analyzed from various angles in order to enrich the system of blockage mechanism and improve polymer flooding effect.
