GAS RESOURCE OF BOHAI BAY AND ITS SURROUNDING AREAS

摘要: 渤海湾盆地环海3大坳陷及海域天然气资源各具特色,特别是海域,其演化、发育是周边3大坳陷的延伸与交汇,有独特的地质特性,再加之郯庐断裂贯穿整个海域,对其油气成藏有重大影响。天然气的形成受控于母质类型及演化程度。大港、辽河油区有广阔天然气勘探前景。胜利油区的腐泥型优质源岩在低熟—成熟及其过渡阶段已大量生成石油。海域有众多富生烃凹陷,烃类可演化到过成熟阶段,加之快速沉积和烃类生成产生的超压等条件,油气资源可与周边3大坳陷媲美。Abstract: Gas resource in offshore part and its surrounding Huanghua, Liaohe and Jiyang depressions in Bohai Bay Basin showed their own characteristics.The offshore is an important part of the basin with special geological character, which is extension of the three depressions.Tanlu fault belt passing through the offshore part played a very important part in hydrocarbon formation and accumulation.Gas generation was controlled by kerogen types and their evolution level.Onshores Dagang and Liaohe oil gas provinces showed favourable gas potential, but Shengli oil province is dominated by oil as a result of tremendous type I kerogen and low maturity.The offshore is a favourable area for gas generation and preservation due to rich source rocks, high maturity and overpressure.Gas resource in offshore is enormous.
