%X 利用现今构造、成藏期古构造、砂体分布、油源断裂匹配关系分析等方法，探讨控制朝阳沟油田杨二段油藏分布的主控因素，指出油藏分布有利区。朝阳沟油田杨二段油藏经历了嫩江组末期早期成藏和后期油藏调整两个阶段，嫩江组末期杨二段古地貌高地与主砂体、油源断裂分布叠置区是原油初次运移的有利区，后期构造变动造成早期油藏向现今构造高部位分布的构造圈闭和岩性圈闭方向调整。调整路径为新、老油藏之间的断裂和连片分布的砂体。朝阳沟背斜区、翻身屯背斜南段及南部斜坡区是后期油气调整最有利地区。<br />
The main controlling factors of reservoir distribution in Yang 2 Member of Yangyanggou Oilfield are discussed and the favorable areas of reservoir distribution are pointed out by using the me-thods of present structure, paleostructure of reservoir forming period, sand body distribution and oil-source fracture matching. The reservoir of the second member of the Yang Formation in Chaoyanggou Oilfield has experienced two stages: early reservoir formation in the late Nenjiang Formation and late reservoir adjustment. The paleogeomorphic plateau of the second member of the late Nenjiang Formation, along with the main sand body and the overlapping area of oil source fault distribution, is a favorable area for the initial migration of crude oil. The late tectonic changes caused the adjustment of the early reservoir to the structural trap and lithology trap distributed in the high structural position. The adjustment path is the fracture and contiguous sand body between the old and new reservoirs. The Chaoyanggou anticlinal area, the south section of the Zhuantun anticlinal area and the southern slope area are the most favorable areas for oil and gas adjustment.
