特低渗透油藏 CO2 驱注采参数优化设计
Injection-production parameters optimization of CO2 flooding in extra-low permeability reservoir
摘要
Abstract
According to the geological characteristics of the reservoir and the actual problems of water injection ,CO2 flooding has been studied for a special peripheral extra-low permeabil-ity reservoir of Daqing Oilfield by using numerical simulation methods .Research shows that cyclic gas injection is the reasonable gas injection manner of CO2 flooding .On the basis of the principle of orthogonal experimental design ,the importance order of the influence of injec-tion-production parameters on oil increment and oil drainage rate is as follow s :injection rate , the injection cycle ,production pressure and oil extraction manner ;meanwhile the best combi-nation of injection-production parameters has been optimized :gas injection rate of 500 m3/d , opening two months off a month ,production pressure of 4 MPa ,continuous oil extraction , thus providing theoretical instruction and technical support for mine program development of CO2 flooding .关键词
