Abstract

Maintaining good conditions for petroleum exploitation is an important basis for achieving better exploitation results. At present, the main reservoir conditions of our main oil fields are relatively good, and have entered high water cut, middle and late development. Due to long-term exploitation, the reservoir has suffered a certain degree of destruction, resulting in the rapid rise of aquifers and sharp reduction of production. It has certain influence on the output of oil and well and the final recovery efficiency of oil field. In order to alleviate the contradiction of rapid reduction of oil production pressure and output in high water cut stage of medium and low permeability reservoir, the development efficiency of reservoir can be improved. By analyzing the high water cut stage of medium and low permeability reservoir, this paper puts forward the comprehensive treatment measures, which provides the idea for realizing the increase of production.
