New Progress in the Study of Siliceous Rock Oil and Gas in Nadanha Single Terrain

Abstract

The siliceous shale oil and gas in Nadanhada terrane has been studied through field geological survey, geochemistry and sedimentary petrology. The results show that the area belongs to a good shale reservoir, and the siliceous rock is brittle and suitable for exploitation. The abundance of organic matter is relatively high. From west to east and from south to north, the abundance of organic matter increases and the maturity of organic matter decreases. From west to east and from south to north, the dynamic metamorphism and thermal contact metamorphism of the siliceous rocks in the Nadanhada terrane are gradually weakened, and the folds and magmatic intrusion of the strata are alleviated.
