东濮凹陷黄河南地区具有丰富的天然气资源。根据已有的地质资料 ,对马厂构造的天然气分布特征进行了描述 ,从气藏的地质特征、气藏的流体性质及气藏压力等多方面分析了天然气成藏条件。研究结果表明 ,东濮凹陷的马厂构造中天然气显示活跃 ,气藏类型多为反向屋脊断块型 ,其气藏流体性质以聚集煤层气为主 ,属于低压气藏。马厂地区天然气成藏条件优越 ,具有良好的天然气资源量和可观的勘探潜力
The Huanghe South area in Dongpu Depression is rich in natural gas resources. Based on the existing geological data, the distribution characteristics of natural gas in Machang plant are described. The gas accumulation conditions are analyzed from the aspects of the geological characteristics of the gas reservoir, the fluid properties of the gas reservoir and the pressure of the gas reservoir. The results show that natural gas is active in the horse factory structure in Dongpu Depression, and the gas reservoirs are mostly inverted roof block faulting. The fluid properties of the gas reservoirs are mainly concentrated coal bed gas and belong to low pressure gas reservoirs. Natural gas accumulation conditions in Machang area are excellent, with good natural gas resources and considerable exploration potential
