江汉平原东部构造演化对局部构造形成及油气成藏的控制作用

摘要

The study area is located in the northeast of the Middle Yangtze plate, in a composite basin range system formed by two orogenic belts of East Qinling-Dabie and Jiangnan-Xuefeng mountains as well as their foreland thrust belts. The regional tectonic evolution is characterized by multiple tectonic stress field, multi -stage tectonic movement, and multiple level of tectonic deformation, showing regional geologic structure of "two mountains holding one basin" , generally presented as ramp interference, north -south zonation and vertical superposition. The control action of tectonic evolution on local structure distribution and hydrocarbon accumulation has been analyzed based on 2D seismic interpretation and research for the study area and using balanced section technique to deepen the research on structural evolution and deformation characteristics.%研究区位于中扬子板块东北部,处于东秦岭—大别山和江南—雪峰2个造山带及其前陆冲断带联合而成的复合盆山体系中,区域构造演化具有构造应力场的多重性、构造活动的多期性、构造变形的多层次性等特点,具有“两山夹一盆”的区域地质结构,整体具有对冲干涉、南北分带、纵向叠置的结构特征.通过对工区二维地震资料解释与研究,通过平衡剖面技术深入构造演化及变形特征的研究,分析构造演化对区内局部构造分布规律及油气成藏的控制作用.
