高含水老油田深度开发面临挑战及发展方向OA北大核心CSTPCD

High water-cut mature oilfields are the main body of oil reserves and production in China,with great sig-nificance for ensuring national energy security and supporting high-quality development of national economy.On the basis of fully affirming the important strategic position of high water-cut mature oilfields in China,current develop-ment situation of classified high water-cut reservoirs is deeply analyzed,pointing out 3 challenges faced in achiev-ing high-quality development,including oil recovery improving,low-cost and efficient development and green de-velopment throughout entire life cycle,and overall development direction and core key technologies of high water-cut mature oilfields are clarified.First is to develop precise development technology with the goal of"significantly increasing oil recovery".Second is to develop production engineering technology with the goal of"intelligent and ef-ficient".Third is to develop surface engineering technology with the goal of"efficient,green and intelligent".The research points out direction for long-term high-quality development of high water-cut mature oilfields in China in the future.
