摘要: 在煤沼环境的沉积作用分析基础上,提出区域性分布的煤层具有可对比性和等时性,这种煤层可以作为成因层序边界.以吐哈盆地侏罗系为实例,研究了这种层序边界的特征,进行了层序和体系域的划分,从而为层序地层学研究奠定基础,为油气生储盖评价提供科学依据.

Abstract: Based on analysis of sedimentation in coal-swamp environment,it is concluded that regionally extended coal seams have the correlatability and isochronism,which recorded the termination of a depositional event or episode.So a coal seam can be used as a genetic stratigraphic sequence boundary(SB).With Jurassic formations of Tu Ha basin taked for an example the features of the SB were studied,then sequences and systems tract are divided,so that the study sets up a basis of sequence stratigraphy research and provides scientific proofs for oil and gas assessment of source rocks,reservoirs and seals.
