Yanchang Group Tight Reservoir Study in Ordos Basin [PDF]

Advances in Intelligent Systems Research, 2015
Yanchang group of southeastern Ordos basin are tight oil accumulation conditions of the research degree is low, the tight oil exploration has not obtained the big breakthrough. To evaluate tight oil exploration prospect of southeastern basin Yanchang group, through to the sedimentary, reservoir, cap rock, oil and gas migration, such as research, in ...

Coupling Landscape Patterns and Ecosystem Services With Sustainable Development Goals for Regional Sustainability: Evidence From the Yellow River Basin

Land Degradation &Development, EarlyView.
ABSTRACT Human activities are accelerating ecosystem degradation, making regional sustainability transitions increasingly urgent. Although the United Nations Sustainable Development Goals (SDGs) provide a unified global framework for action, their implementation at the regional scale still lacks operational approaches for evaluating whether progress in

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Evolution of Hydrogeochemistry in the Haolebaojinao Watershed of the Ordos Basin, China

Sustainability, 2023
The exploitation of groundwater in arid and semi-arid areas, especially in basins where groundwater is intensively exploited, is likely to have adverse effects on the originally fragile ecological environment, which also greatly alter the hydrogeochemical evolution process.

Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Two Distinct Growth Styles of Riedel Shear Zones in Cratonic Strike‐Slip Fault System, Tarim Basin, NW China

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Palaeostructure, evolution and tight oil distribution of the Ordos Basin, China

Oil & Gas Science and Technology, 2019
Whether or not the tight oil in the Triassic Yanchang Formation of the Ordos Basin is controlled by structural factors is a controversial issue, the relationship between the structural factors of the strata and the distribution of tight oil is limited to

Spatially Heterogeneous Impacts of Urbanization in Reshaping the Dry and Hot Extremes Across Chinese Cities

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Escalating climatic hazards have posed considerable challenges to urban resilience and sustainable development. By integrating national‐scale meteorological data, this research elucidates how urbanization reshapes the dry and hot extremes across China at various temporal scales and within a regional framework.

Carbon and Hydrogen Isotopic Reversals in Highly Mature Coal-Derived Gases: A Case Study of Paleozoic Gases in the Southern Ordos Basin, China

Geofluids, 2019
The compositional carbon isotopic series δ13C-CH42.4%. Where 2.4%>Ro>2.0%, almost all gases display partial isotopic reversal, with δ13C-CH4>δ13C-C2H6 or δ13C-C2H6>δ13C-C3H8. Carbon isotopic reversal in coal-derived gases is not caused by abiotic origin,
