| 摘 要： | 潍北盆地煤、油、天然气共生。根据天然气组分与碳同位素特征并结合烃源岩有机质类型及热演化阶段等资料,将天然气分为细菌气、细菌-成熟油型气、低熟煤型-油型气、成熟油型-煤型气、煤型气等6种成因类型。不同类型天然气在平面上的分布总体上呈东西向带状展布的格局是明显的,由北而南依次为高成熟煤型气、成熟油型-煤型气、低熟煤型-油型气和细菌气。各种类型天然气分布规律的揭示为该区天然气勘探开发提供了重要依据。

| Abstract: | Coal,oil and natural gas are coexisting in the Weibei Basin.According to the component and carbon isotope characteristics of natural gas and combining with organic matter types,thermal evolutionary stages and other data of hydrocarbon source rocks,natural gas was classified into bacteriogenetic gas,bacterial-mature oil-typed gas,low mature coal-oil-typed gas,mature oil-coal-typed gas,coal typed gas and other six genetic types.It is clear that different types of natural gas take WE zonal distribution planarly on the whole,that is,high-mature coal-typed gas,mature oil-coal-typed gas,low mature coal-oil-typed gas and bacteriogenetic gas from north to south in turn.The revealment of distribution rules for various types of natural gas provides an important basis for the exploration and development of natural gas in the area. |
