FORMING OF GAS POOLS IN THE CHENJIAZHUANG SALIENT, THE BOHAIWAN BASIN

摘要: 陈家庄凸起位于沾化凹陷和东营凹陷之间。该区天然气具有双气源,北部天然气主要来自渤南洼陷,南部天然气主要来自利津洼陷。深部天然气沿断层向上运移,形成古生新储型气藏。储集层主要由馆陶组辫状河沉积砂体和明化镇组曲流河沉积砂体组成;发育有馆陶组、明化镇组两套盖层,成藏和保存条件优越。浅层气的平面分布主要受构造背景和沉积相带控制,馆陶组气藏以气顶气为主,明化镇组气藏以气层气为主。浅层气纵向分布受地层砂泥比控制。Abstract: The Chenjiazhuang salient is located between Zhanhua sag and Dongying sag.Oil and gas exploration there started in the 1960s.Up to now,a lot of natual gas accumulations are found.The natual gas in this area has two sources.They are from the Bonan depression and the Lijin depression.The deep natual gas migrates upward along faults,forming palaeo-generated-newly-stored type of gas accumulation.The reservoir is mainly composed of the braided channel sedimentary sand in Guantao formation and meandering river sedimentary sand in Minghuazhen formation.Moreover,the capping beds over Guantao formation and Minghuazhen formation have developed.The conditions forming gas accumulation are excellent.The plane distribution of the shallow gas in this area is mainly controlled by structural setting and sedimentary facies.The longitudinal distribution of the gas is mainly controlled by the ratio of sandstone to mudstone in formations.Exploration of natual gas in Chenjiazhuang area has a widely promising future.
