Tectonic evolution of the Sichuan Basin, Southwest China
Earth-Science Reviews, 2021Abstract Surface deformation in continental interiors is typically coupled to processes at depth. However, in the Sichuan basin, east of the Tibetan Plateau, recent seismic data detect Neoproterozoic subduction and rifts, indicating long-term tectonic quiescence of the basement. The Sichuan basin is characterized by two episodes of weak extension and

Characteristics of air pollution in different zones of Sichuan Basin, China
Science of the Total Environment, 2018Sichuan Basin, located in southwest China, has been ranked as the fourth of heavily air polluted regions in China partly due to its deep mountain-basin topography. However, spatial-temporal distribution of air pollution over the basin is still unclear due to the lack of monitoring data and poor knowledge. Since January 2015, six criteria air pollutants

Origin of Subsurface Brines in the Sichuan Basin
Groundwater, 1997Abstract Subsurface brines in the Sichuan Basin occur within sedimentary rocks ranging in age from Sinian to Cretaceous, especially within rocks of Triassic age. The chemical and isotopic compositions of the brines and general geological considerations suggest that the Sichuan Basin brines are derived from waters of different origin ...

The water footprint of hydraulic fracturing in Sichuan Basin, China
Science of The Total Environment, 2018Shale gas is likely to play a major role in China's transition away from coal. In addition to technological and infrastructural constraints, the main challenges to China's sustainable shale gas development are sufficient shale gas production, water availability, and adequate wastewater management.

ACHIEVEMENTS IN THE DEVELOPMENT OF DEEP DRILLING TECHNIQUE IN SICHUAN BASIN
Proceedings of International Meeting on Petroleum Engineering, 1988ABSTRACT Sichuan basin is the primary carbonate deposition basin in China, which is rich in natural oil and gas resources and has a very long drilling history. The geological conditions in the basin are very complex, which causes a lot of difficulties in deep drilling.

Chemical characteristics of rainwater in Sichuan basin, a case study of Ya’an
Environmental Science and Pollution Research, 2016Rainwater chemistry was investigated at a semi-rural site in Ya'an, Sichuan basin with rain samples collected from May 2013 to July 2014. The rainwater pH values ranged from 3.25 to 6.86, with an annual volume-weighted mean (VWM) of 4.38, and the acid rain frequency was 74 %.

Origin of Flowback and Produced Waters from Sichuan Basin, China
Environmental Science & Technology, 2018Shale gas extraction through hydraulic fracturing and horizontal drilling is increasing in China, particularly in Sichuan Basin. Production of unconventional shale gas with minimal environmental effects requires adequate management of wastewater from flowback and produced water (FP water) that is coextracted with natural gas.

Northeastward propagation of nocturnal precipitation over the Sichuan Basin
International Journal of Climatology, 2020AbstractThe Sichuan Basin (SCB) is located to the east of the Tibetan Plateau (TP) and features nocturnal precipitation. This study explores spatial variation of nocturnal precipitation during the warm season over the SCB using high spatiotemporal resolution merged precipitation products from 2008 to 2017.

Modeling for the Burial and Subsidence History of the Sichuan Basin
Chinese Journal of Geophysics, 2003AbstractBased on data of stratigraphic thickness, ages, lithology, density, porosity and seismic sections, sedimentary and subsidence histories can be obtained by plotting subsidence curves and backstripping analysis. The study indicates that the difference between total subsidence and tectonic subsidence in the Sichuan basin decreases as the ...

Water Availability for Shale Gas Development in Sichuan Basin, China
Environmental Science & Technology, 2016Unconventional shale gas development holds promise for reducing the predominant consumption of coal and increasing the utilization of natural gas in China. While China possesses some of the most abundant technically recoverable shale gas resources in the world, water availability could still be a limiting factor for hydraulic fracturing operations, in ...
