提升孤东油田B区5-6单元聚驱效果研究

Study on improving the effect of 5-6 unit polymer flooding in B area of Gudong Oilfield

三次采油目前已经成为各大油田提高采收率的重要手段。孤东油田B区油藏地质条件发育较好,适合聚合物驱油,但是受制于各方面原因未能充分发挥潜力,总体见效不均衡,本文通过对影响注聚效果的原因进行分析,提出改善意见,促进该区高质量发展,同时为同类型油藏聚合物驱提供借鉴。

Tertiary oil recovery has become an importantmeans to enhance oil recovery inmajor oil fields.Reservoir geological conditions in Gudong Oilfield B area are well developed,which is suitable for polymerflooding.However,due to various reasons,the potential is not fully realized,and the overall effect is uneven.This paper analyzes the reasons affecting the injection polymerization effect,and puts forward suggestions for improvement,so as to promote the high-quality development of this area and provide reference for polymer flooding of similar reservoirs.
