中国海相克拉通盆地古隆起的活动性与油气分布
The Activities of Paleo-uplifts and Distribution of Oil and Gas in Marine Craton Basins, China
摘要
Abstract
Marinecratonic basins of China are characterized by old ages,small scale,multiple activities and poor stability.However,the paleouplifts in marine basins are relatively small in sizes but strong in activity.On the basis of geological structures and tectonic activities,paleouplifts have been divided into stable,inversion,migrated,sinked and dismembered types.Combined with the latest progress in oil and gas exploration,this study analyzed controlling effect of each uplift on hydrocarbon accumulation.Results show that oil and gas is mainly concentrated in the core and the slope sections of stable paleo-uplifts,in the slope and the hub areas of inversion paleouplift,the slope of migrated paleo-uplift.The sinked and dismembered paleo-uplifts play a minor role in oil and gas accumulation.With the exploration towards deeper field,the characteristics of "near source and excellent reservoir" are more obvious.The early shortterm exposure of karst reservoir and multi period faulted belt on the slope of paleo-uplifts near source rocks is an important newly discovered area for oil and gas.The paleo-uplift and extensional trough superimposed parts have superior accumulation matching relationship,and become new hot spots for deep sequence oil and gas exploration.The Aman transition area of Tazhong and Tabei paleo-uplifts in the Tarim basin,the both sides of Proterozoic extensional groove under central paleo-uplift in the Ordos basin,and the both sides of Sinian-Cambrian extensional groove under central paleo-uplift in Sichuan basin are favorable areas for accumulation of superlarge or large oil and gas fields in deep marine strata.关键词
