摘　　要：辽河坳陷曙古潜山勘探至今已40余年,但自20世纪90年代以来,一直没有实现潜山勘探新突破,为此基于前人研究资料并结合潜山岩性的重新认识,对内幕地层时代进行重新厘定。通过内幕地层精细对比、构造特征梳理及试油试采等资料,对潜山油气成藏规律进行重新评价,并以此为基础部署实施探井,在潜山风化壳及内幕勘探中取得了重大发现,在明确潜山地层时代的同时,也为潜山分层系勘探提供了科学依据。Shugu buried hill exploration has been carried out for more than forty years in Liaohe depression,but there is no breakthrough since the 1990s.Therefore,based on the previous research data and combined with the new understanding of the buried hill lithology,the age of the inner strata need to be redefined.The law of hydrocarbon accumulation in buried hill is re⁃evaluated through the detailed correlation of the inside strata,the sorting of the structure characteristics and the data of oil test and production.On this basis,exploration wells are deployed and significant discoveries are made in weathering crust and inner exploration of buried hill,which not only defines the age of buried hill strata,but also provides a scientific basis for stratification exploration of buried hill.
