【摘要】 通过对豫西地区野外地质调查和二维地震资料的精细解释,结合差异构造变形分析及成藏动力学研究,综合分析了研究区的构造变形特征及其与油气成藏模式之间的关系。根据构造样式的基本概念、分类原则,结合研究区的构造特征,将构造样式分为基底卷入型、盖层滑脱型、构造样式叠加3大类。基底卷入型分为压扭性断块与基底逆冲、扭动构造、基底翘曲共3种次级构造样式;盖层滑脱型主要为滑脱正断层的构造组合;构造样式叠加包括压性断裂组合和反转构造。构造对油气成藏的主控因素为断裂与古地貌,而区内主要成藏模式为自生自储型和次生型。更多还原

【Abstract】 Through outcrop investigation and a detailed interpretation of 2Dseismic data from the western Henan Area,combined with the analysis of differential tectonic deformation and the study of hydrocarbon accumulation dynamics,the relationship between structural deformation characteristics and hydrocarbon accumulation pattern was comprehensively analyzed.According to the basic concept of the structural style,principles of its classification,and combined with the structural characteristics in the studied area,the structural styles were divided into three categories of basement involved type,caprock sliding type and superposition of tectonic style.Basement involved type was divided into transpressional fault block and basement thrust,wrench structure and basement warp;the structural sliding was mainly the tectonic combination of normal sliding fault,while the superposition of tectonic style included included a compressional fault combination and reversed structures.The major control factors of structure to the hydrocarbon accumulation are fault and palaeogeomorphology,while the main hydrocarbon accumulation patterns in the area are self generation and self storage secondary mode.更多还原
