伸展盆地中的变换走滑构造及其油气地质意义
Transform strike-slip structures in extensional basins and their hydrocarbon significance
摘要
Abstract
Transform structures are commonly developed in extensional basins.The transform strike-slip struc-tures are passive strike-slip structures with significant horizontal displacement between different extensional fault domains to maintain regional or local strain conservation and transfer displacement between extensional faults,forming under non-strike-slip stress regimes.The transform strike-slip structures are commonly developed in the extensional basins in East China,and could be divided into two major types:transform strike-slip faults and trans-form strike-slip zones according to whether obvious strike-slip faults formed or not,and their structural styles are related to the difference in extension of faults on both sides.Furthermore,based on the tendency of the extension-al faults on both sides,each type could be divided into three subtypes:i.e.,opposite tendency,same tendency,and complex tendency.The transform strike-slip structures play an important role in controlling the hydrocarbon accu-mulation,and provide the base for the explanation and identification of structural traps in the extensional basin.The transform strike-slip structure causes the bending and deformation of local strata and controls the distribution of paleotopography or micro-paleotopography,and controls the development of sedimentary reservoirs.In addi-tion,transformation strike-slip structures can act as favorable zones for oil and gas accumulation,as well as separ-ators for oil and gas distribution.关键词
