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 %.

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 ...

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.

Geochemical characteristics of natural gases in the Sichuan basin
Chinese Journal of Geochemistry, 1985The Sichuan basin is one of the largest gas-oil-bearing basins in China. Ool and. gas pools occur in Mesozoic, Paleozoic and Proterozoic strata in this basin, with natural gases being dominant.

The application of prestack inversion in Guang'an area, Sichuan Basin
SEG Technical Program Expanded Abstracts 2007, 2007In recent years, the Xujiahe formation of the Upper Triassic in the Sichuan Basin has become an important objective for gas exploration. This is especially true in the Xu6 Section where sandstone has developed, but not all sandstones are effective reservoirs.

Characteristics and origins of carbonaceous aerosol in the Sichuan Basin, China
Atmospheric Environment, 2014Abstract The Sichuan Basin is a low visibility area in southwest China, where the hilly and basin topography, plus humid and stagnant weather, lead to unique pollution patterns. To identify the characteristics and sources of carbonaceous aerosols, one-year record of 24-h PM2.5 samples were analyzed for organic carbon (OC) and elemental carbon (EC ...

Implications of ozone transport on air quality in the Sichuan Basin, China
Environmental Science and Pollution ResearchOzone pollution is formed through complex chemical and physical processes closely associated with emissions, photochemical reactions, and meteorological conditions. The objective of this study is to quantify the contributions of meteorological chemical formation, vertical transport, and horizontal transport to air quality during spring and summer in ...

Lower Cretaceous paleosols and paleoclimate in Sichuan Basin, China
Cretaceous Research, 2016Abstract Abundant Lower Cretaceous (Berriasian–Hauterivian) paleosols have been recognized in the Sichuan Basin, along with the preserved pedogenetic features, e.g., soil horizons, soil structure, root traces and pedogenic nodules. Chemical, geochemical and mineralogical analyses were used to examine the paleosols.

The Deep Structure Feature of the Sichuan Basin and Adjacent Orogens
Acta Geologica Sinica - English Edition, 2015AbstractThe basin‐mountain system in the Sichuan Basin (SCB) reflects the main tectonic activity and the orogenic denudation in this region. The seismic probing work reveals the deep structure of the basin‐mountain system. The seismic work was re‐sampled to the Moho depth and the sedimentary thickness as well as the P‐wave velocity‐depth function to ...
