庙西北凸起不整合面结构及其与油气成藏关系
The Architecture of Unconformity in the Miaoxibei Uplift and Its Effect on Hydrocarbon Accumulation
【摘要】 不整合面在油气成藏中具有重要的作用。根据已钻井岩心、测井等资料,结合三维地震资料对庙西北凸起地区不整合结构独特性以及在油气成藏中的作用进行了详尽的分析。不整合面为油气运移提供运移通道、为油气成藏提供储集空间,在潜山形成大规模油气成藏,同时为浅层新近系油气成藏起到"中转站"的作用,形成油气的二次运移。
【Abstract】 Unconformity plays an important role in oil and gas accumulation.Based on drilling core and logging data from the drilled wells,combined with 3D seismic data,an detailed analysis of the unconformity architecture and its effect on hydrocarbon accumulation, unconformity provides migration pathways and accumulation reservoir space for oil and gas migration,forms large-scale oil and gas accumulation in burial hill,at the same time,unconformity plays a "transit station" role in the shallow Neogene hydrocarbon accumulation,forms secondary migration of oil and gas.This paper has a good reference value for other parts unconformity study of Bohai Sea with similar structures.
