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。
The Chenjiazhuang bulge is located between Zhanhua Depression and Dongying Depression. The natural gas in the area has a double gas source, the northern natural gas mainly comes from the Bonan depression, and the southern natural gas mainly comes from the Lijin depression. Deep natural gas migrates up the fault to form Paleozoic gas reservoirs. The reservoirs are mainly composed of braided river sedimentary sand body of Guantao Formation and meandering stream sedimentary sand body of Minghua Town Formation. There are two sets of cap rocks of Guantao Formation and Minghuazhen Formation, which have favorable conditions for hydrocarbon accumulation and preservation. The plane distribution of shallow gas is mainly controlled by tectonic setting and sedimentary facies. The gas in the Guantao Formation is dominated by the gas cap and the gas in the Minghua Zhen Formation is dominated by gas. Longitudinal distribution of shallow gas is controlled by formation sand and mud ratio.
