鄂尔多斯盆地下古生界含气系统及勘探方向

THE LOWER PALEOZOIC GAS BEARING SYSTEM OF THE ORDOS BASIN AND ITS EXPLORATION DIRECTION

含油气系统作为油气勘探过程中一种新的研究思路和方法 ,目前正受到越来越多学者的重视。文中依据油气源、油气赋存的层位及储盖组合 ,将鄂尔多斯盆地初步划分为中生界含油气系统、上古生界含气系统和下古生界含气系统。同时 ,重点描述了下古生界含气系统的特征 ,总结了下古生界天然气分布的规律 。

As a new thinking and method of research during hydrocarbon exploration, the petroliferous system has got attention from more and more scholars recently. In this paper, the Ordos Basin is preliminary divided into the Middle, the Upper and the Lower Paleozoic three gas bearing systems according to the source of hydrocarbon, the stratohorizon of hydrocarbon occurrence and the assemblage of reservoir and cover. At the same time, the characteristics of the Lower Paleozoic gas bearing system are described emphatically, the distributive rule of the Lower Paleozoic natural gas is summarized, and the favorable prospecting zones potential are pointed out.
