摘　　要：南阳凹陷东部的魏岗和张店地区断层极为发育、构造破碎,处于多物源发育区,属典型的复杂小断块稀油油藏区域,经过40年的开发已处于高含水开发的后期阶段,面临的主要问题是无后备储量接替。根据储层沉积特征、主控断裂产状及二者匹配关系,预测构造和断层+岩性圈闭发育部位,利用丰富的钻井油气显示资料,结合构造演化及油气运移路径研究结果,提出了牛三门油源平面上油气显示具有“两贫、两富、两连片”的分布特点,油气运移距离在15km左右,在油气运移路径范围内新发现有利圈闭36个,已完钻4口均钻遇油层,并试获工业油流,滚动增储效果显著。Weigang and Zhangdian areas in the east of Nanyang depression have extremely developed faults and broken structures.They are in the development area of multiple sources.They are typical thin oil reservoirs with complex small fault blocks.After 40 years of development,they have been in the late stage of high water cut development.The main problem is that there is no reserve replacement.According to the sedimentary characteristics of the reservoir,the occurrence of main control faults and their matching relationship,the development positions of structures and faults+lithologic traps are predicted;Based on the abundant drilling oil and gas display data,combined with the results of structural evolution and oil and gas migration path research,it is proposed that the oil and gas display on the Niusanmen oil source plane has the distribution characteristics of"two poor,two rich and two connected",the oil and gas migration distance is about 15km,36 favorable traps are newly found within the oil and gas migration path,4 oil layers have been drilled,and industrial oil flow has been tested,and the rolling reservoir increase effect is remarkable.
