摘　　要：春光油田排2单元具有"埋藏浅、油品好、采油指数高、边水能量强"的特点,以油藏数值模拟技术为主,结合油藏工程方法的综合研究,重点分析了排2单元油井见水后含水率变化特征和上升原因,以及水淹井措施治理后含水变化情况,明确了强边水稀油油藏的含水变化规律,为油田的高效开发提供技术支持。Pai-2 unit of Chunguang oil field is characterized by'shallow buried depth,good oil properties,high productivity index and strong edge water energy'.Focused on reservoir numerical simulation technology,combined with the comprehensive research method of reservoir engineering,water cut change characteristics and rising reasons after water breakthrough of oil wells of Pai-2 unit have been analyzed.Through water cut change after control measures of water flooding wells,the water cut change regularities of thin oil reservoir with strong edge water have been made clear,and it provides technical support for the efficient development of oilfield.
