辽河坳陷西部凹陷鸳鸯沟地区层序地层划分与岩性圈闭预测
|
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。
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,the distribution of lithological traps in this area were predicted. High production oil flow in the target horizons in well Jin310 was discovered, which proved that the favorable developed belt of lithological hydrocarbon reservoirs distributed under the break slope of well Jin1.
