| 摘 要： | 运用层序地层学的理论与方法,综合分析岩心、测井以及地震等资料,将辽河坳陷西部凹陷鸳鸯沟地区古近系裂陷期的沉积充填划分为4个超层序和8个三级层序.该区主要发育同沉积断裂坡折型层序,坡折带之下是岩性油气藏发育的主要部位.结合该区层序格架中油气分布规律,对该区岩性圈闭进行了预测.通过钻探锦310井,在预测目的层段试油获高产油气流,证实了锦1断裂坡折带之下为西部凹陷有利的岩性油气藏发育区带.

| Abstract: | Based on sequence stratigraphy theory and method,and the comprehensive analysis of cores,seismic and logging data,the depo-sitional filling styles of Palaeogene rifting period in Yuanyanggou area of west Liaohe Depression were divided into 4 second-order sequences and 8 third-order sequences. The sequence with syn-depositional faulted slope-break belt is the main type in this are-a. Lithological hydrocarbon reservoir distributed mainly under the break slope. Combined oil and gas occurrence in sequence frame... |
