摘要
以柴达木盆地昆北断阶带为例,应用地震成藏学理论,对地震资料揭示出来的信息,即精细构造解释开展的断裂构造特征、断裂活动演化及不整合面识别等进行分析研究,认为昆北地区具有古构造背景、储盖组合良好、圈闭类型多样特征,尽管昆北断阶带处于主力生烃洼陷之外,在深大断裂-不整合沟通输导下,成藏条件优越,发育多类型、大面积复合油气藏。从而对于指导源外低勘探区油气勘探,发展油气成藏理论具有重要的意义。
Taking Kunbei fault-terrace belt of Qaidam Basin as an example, based on seismic-petroleum accumulation science theory, the information revealed from seismic data, fault structure, evolution of fault activity and unconformity recognition and so on, was researched. The results indicate that Kunbei has the characters of ancient tectonic background, fine reservoir-cap combination and trap type diversity.Though Kunbei fault-terrace belt is outside the main hydrocarbon generation sag, under communication and transportation of the deep fault unconformity, accumulation conditions is favorable and multi-type, large area composite reservoirs were developed. This conclusion is of great significance for guiding source outside the low exploration area of oil-gas exploration and developing oil-gas accumulation theory.
