Geochemical characteristics of Dongsheng sandstone-type uranium deposit, Ordos Basin

Chinese Journal of Geochemistry, 2007
Generally, sandstone-type uranium deposits can be divided into three zones according to their redox conditions: oxidized zone, ore zone and reduced zone. The Dongsheng uranium deposit belongs to this type. In order to study its geochemical characteristics, 11 samples were taken from the three zones of the Dongsheng uranium deposit. Five samples of them

AVO Research on Coalbed Methane Reservoirs in East Ordos Basin

International Petroleum Technology Conference, 2013
Abstract DESCRIPTION: In east Ordos basin, there are plenty of coalbed methane (CBM) resources. However, the coalbeds are of strong heterogeneity due to laterally variant thickness and gas contents. Consequently, the heterogeneity gives rise to the great challenges for fine

The Rock Mechanical Properties of Lacustrine Shales from Ordos Basin

International Petroleum Technology Conference, 2019
Abstract Abundant shale oil and gas resources have been discovered in the Zhangjiatan shale of the Yanchang formation in ordos basin in recent years. Zhangjiatan shale is a typical lacustrine shale, which is different from Marine shale in physical properties. Most previous research has focused on Marine shale.

Burial Metamorphism of the Ordos Basin in Northern Shaanxi

Acta Geologica Sinica - English Edition, 1993
Abstract Burial metamorphism has been found in the Ordos basin of northern Shaanxi. On the basis of a rather intensive study of burial metamorphism of sandstone, it has been shown that the evolution from diagenesis to metamorphism involves four stages: cementation of clay minerals, regrowth of pressolved quartz and feldspar, cementation of carbonates ...

Genesis of tight sand gas in the Ordos Basin, China

Organic Geochemistry, 2014
Abstract Based on molecular and stable carbon isotope composition of a large collection of gas samples and integrated with the geological context, this article discusses the genesis and migrational characteristics of natural gases from the giant tight sand gas fields of the Upper Paleozoic strata, Ordos Basin (UPOB).

Tectonic Response Characteristics of the Yanshan Movement in the Ordos Basin - Insights from the Yanshanian Unconsolidated Surface in the Ordos Basin

The Yanshan Movement period (Middle Jurassic-Late Cretaceous) represents a critical period of deformation and magmatic development in China, during which the tectono-sedimentary pattern of the North China Craton underwent a major transformation. A large stratigraphic record is preserved in the relatively stable Ordos Basin. It provides a possibility to

Fractal Distribution of Paleotrough and Exploration Potential in Ordos Basin

2019
In Ordos Basin, gas exploration practice indicated that the spatial distribution of Ordovician paleotrough played an important role in gas reservoirs quality. In order to optimize exploration target, the paleotrough distribution was studied by fractal theory. There are three procedures in practical operation. Firstly, the relationship between reservoir
