| 摘 要： | 库车油气系统中、新生界流体压力纵向结构可分为台阶式、中凸式、均斜式 3种类型。平面分布可分两个带 3个区 :北带主要是台阶式压力结构分布区 ,南带的大部分是中凸式压力结构分布区 ,南带的南缘为均斜式压力结构分布区 ,构成不同类型的封存箱。这种压力结构分异主要是喜玛拉雅晚期 ( 5Ma)天山向南强烈推挤造成的 ;喜玛拉雅早期 ,整个油气系统压力结构大体是一致的 ,深浅层基本为正常压力 ,也即均为均斜式压力结构分布区。喜玛拉雅早、晚期的流体压力封存箱规模不等 ,油气运聚的环境不同 ,因而不同时期、不同地带具有各不相同的油气成藏机制。初步可概括为 3种机制和 3种成藏模式 :早期封存箱内成藏机制———牙哈模式 ;晚期封存箱内成藏机制———克拉苏模式 ;封存箱外成藏机制———大宛齐模式

| Abstract: | There are three types of vertical structure of fluid pressure in the Kuqa petroleum system: staircase, drumlin and isocline. There are three fluid pressure regions in the system: the staircase fluid pressure region is distributed in the north zone, the drumlin fluid pressure region is the main part of the south zone, and the southern edge of the south zone is occupied by the isocline fluid pressure region.Various kinds of fluid pressure compartments were constructed.The differentiation of fluid pressure structure should be caused by compression toward south from the Tianshan fold belt in the late period of the Himalaya cycle (5Ma).In the early period of the Himalaya cycle there were isocline fluid pressure region in the whole petroleum system ,being normal pressure system. The early period compartment reservoir forming mechanism- Yaha Model,the late period compartment reservoir forming machine process-Kelasu Model and the reservoir forming machine process outside compartment-Dawanqi Model exist in each zone and each period of time respectively in the Kuqa petroleum system. |
