Research on Sedimentary Environment of the Wayaobao Formation in Ordos Basin

Applied Mechanics and Materials, 2013
Wayaobao Formation of late Triassic, in Ordos Basin is composed of clastic rocks, such as grey green thick-bedding medium-coarse-grained lithic arkose, lithic feldspathic sandstone, fine-medium-grained lithic feldspathic greywacke, quartzose feldspathic sandstone, et al.

Jurassic Deformation in and Around the Ordos Basin, North China

Earth Science Frontiers, 2007
Abstract The Jurassic era was an important period for tectonic development of the East Asia continent in general, and can be divided into two different deformation stages around the Ordos basin in particular. It was under weak extension during the Early to Middle Jurassic, with the stretching direction in N-S to NNE-SSW, and the stretching ...

Basement faults and volcanic rock distributions in the Ordos Basin

Science China Earth Sciences, 2010
Volcanic rocks in the Ordos Basin are of mainly two types: one in the basin and the other along the margin of the basin. Besides those along the margin, the marginal volcanic rocks also include the volcanic rocks in the Yinshanian orogenic belt north of the basin.

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 ...

A giant lacustrine flood‐related turbidite system in the Triassic Ordos Basin, China: Sedimentary processes and depositional architecture

Sedimentology, 2021
Turbidites have been regarded as an important sedimentary infilling component in both oceans and lakes, but limited studies have been performed on the mechanisms governing the initiation and development of lacustrine turbidite systems.

Upper Paleozoic petroleum system, Ordos Basin, China

Marine and Petroleum Geology, 2005
Abstract The Ordos Basin is a typical lapped basin, including three sequences of strata: early Paleozoic, late Paleozoic and Mesozoic, with a total thickness of 4000–6000 m. Impermeable sealing beds are well developed at the top and base of the upper Paleozoic sequence, separating it from the Mesozoic and the lower Paleozoic strata to form an ...

Climate forcing of terrestrial carbon sink during the Middle Jurassic greenhouse climate: Chronostratigraphic analysis of the Yan’an Formation, Ordos Basin, North China

GSA Bulletin, 2020
Exploring the relationship between coal deposits as an important terrestrial carbon sink and orbital forcing of climate is critical for understanding the global carbon cycle and climate change.

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

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.

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
