摘　　要：冀东南堡陆地油田经过二十多年的开发,整体进入高含水开发阶段,综合含水达到90%以上,但采出程度仅有10%,剩余油富集。为了改善老油田开发效果,针对复杂断块油藏的地质特点,在二次开发理念指导下,对南堡陆地油田Es32+3油藏开展了二次开发技术探索和实践。通过精细油藏描述重构地下认识体系,可以有效提高地质模型精度与剩余油分布认识;通过全面优化层系、井网及开发方式,可以有效提高油藏开发水平;通过改进钻采工程、地面工程配套技术,可以有效提升开发效率。After 20 years of development,Jidong Nanpu oilfield has entered into high water cut development stage,with comprehensive water cut of more than 90% and the recovery degree of only 10%,therefore,the remaining oil is abundant.In order to improve the old oilfield development effect,in view of the geological characteristics of complex fault block oil reservoir,with the secondary development under the guidance of the concept of 'triple',the secondary development technology exploration and practice in Nanpu oilfield land Es_32+3 reservoir has been carried out,and the multilayer complex fault block sandstone reservoir with secondary development pattern has been preliminary formed.Through fine reservoir description,the underground reconstruction system has been established,which can effectively improve the accuracy of geological model and residual oil distribution.Through more means to demonstrate development technical policies and optimize formation series,well patterns and development manners so as to effectively improve the level of reservoir development.By improving the techniques of drilling engineering and ground engineering,the work efficiency can be effectively improved,with reduced energy consumption.
