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