摘要
通过对塔里木盆地北部坳陷区中生界石油地质特征的分析 ,认为其源岩主要为寒武奥陶系 ,其次为二叠侏罗系。继承性隆起、不整合系统和断裂系统纵横交错 ,良好的储层是控制油气分布的主要因素 ,盖层的封闭能力是油气保存的关键。
Through analysis of geologic features of Mesozoic Erathem in the North Depression area of Tarim basin,it is considered that the main source rock is Cambrian Ordovician,and Permian Jurassic is at second place Vertical and horizontal arrangements of successive uplift, unconformable system, fault system and good reservoirs are the key factors for controlling the oil and gas distribution,the sealing capacity of cap rock is critical for oil and gas preservation Strengthening the study of geologic structure and lithology is beneficial to understand the law of Mesozoic oil and gas distribution in the area
