以总结断裂控制特征为目的,采用盆地构造解析法,分析了柴达木盆地北缘断裂特征及油气圈闭成因类型.结果表明:柴达木盆地北缘断裂平面展布具有南北成带,东西分块的特征;纵向上分为发育深层和浅层两大断裂系统;断裂控制褶皱形成和演化;油气分布严格受断裂控制;具有断裂反转型、地层反转型、同生隆起型和挤压褶皱型四大成因类型油气圈闭类型.其中断裂反转型、同生隆起型最有利于油气聚集.
In order to summarize the characteristics of fault control, the basin tectonic resolution method was used to analyze the fault characteristics and hydrocarbon genesis types in the northern margin of Qaidam Basin.The results show that the fault plane in the northern margin of Qaidam Basin has north-south belt, Sub-block features; longitudinally divided into deep and shallow development of the two major fault systems; fracture control fold formation and evolution; oil and gas distribution strictly controlled by the fracture; with fault reversal, stratigraphic inversion type, protuberance uplift and crowded There are four major types of oil and gas trap types, including reverse-fracture type and protuberance-type, which are most conducive to hydrocarbon accumulation.
