本文从阳新统中天然气的硫化氢含量特征;阳新统地层压力低于龙潭组;东吴运动的古岩溶作用使阳新统溶洞、溶斗、溶孔等发育,致使该地层受到强烈割切,从而大大降低了其原可生油一些层段的实际生油能力,反而为上覆龙潭煤系的煤成气提供了良好的运移与聚集空间;和龙潭煤系中形成和存在大量煤成气等事实,说明阳新统气藏的气源主要来自龙潭煤系。
In this paper, the hydrogen sulphide content of natural gas in the Yangxun system is characterized by the Lower Paleoclimate pressure of the Yangsan Formation and the paleokarstification of the Soochow movement, which resulted in the development of the caves, dissolves and dissolved pores in the Yanggocene so that the strata were severely cut Greatly reducing the actual oil production capacity of some layers of the originally available oil and providing a good space for migration and accumulation of the coal-forming gas overlying the Longtan coal series; and the formation and presence of a large amount of coal-formed gas in the Longtan coal system The facts show that the source of the Yangxin gas reservoir is mainly from the Longtan coal system.
