摘要
晚第三纪塔北隆起北部地区有规律地发育一套与区域挤压构造应力场不协调的中新生界张扭性断裂系统 ,且控制了中新生界 ,特别是白垩第三系油气聚集与分布。通过塔北隆起北部地区地震资料解释 ,结合区域地质资料 ,研究了这一特殊断裂系统的主要构造特征、成因机制以及对油聚集的控制作用 。
An extensional shear fault system,which is not accordant with regional compression tectonic stress field,regularly developed during later Neogene in Mesozoic Cenozoic formations in the northern area of Tabei uplift,Tarim Basin. It has controlled oil and gas accumulations and distributions in Cretaceous Tertiary System in this area. On the basis of interpreted seismic data and regional geologic characteristics, this paper presents tectonic characteristics and the genetic mechanism of this fault system and its controlling on oil and gas accumulations in this area. The purposes of this paper are to make a better understand of this special fault system in Tarim Basin and direct petroleum exploration in the northern area of Tabei uplift
