The relationship between helium-rich gas and regional shale in the Sichuan Basin, Southwest China

open access: yesFrontiers in Earth Science
Despite over 60 years of helium development in the Sichuan Basin, the mechanism of helium enrichment remains poorly understood. Helium-rich gas is primarily found as gas composition analysis in the fields.

Different desorption types and geological influencing factors of Silurian shale gas in southeastern Sichuan Basin

open access: yesShiyou shiyan dizhi
The southeastern Sichuan Basin is a key area for the exploration and development of Silurian shale gas in China. In recent years, a number of shale gas wells have achieved good exploration results in this area, providing important support for the ...

Accumulation and exploration enlightenment of shallow normal-pressure shale gas in southeastern Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2023
Based on the drilling, logging, experimental and testing data of Well PD1, a shallow normal-pressure shale gas well in the Laochangping anticline in southeastern Sichuan Basin, the shallow shale gas reservoirs of the Ordovician Wufeng Formation to Silurian Longmaxi Formation (Wufeng–Longmaxi) were investigated in terms of geological characteristics ...

Structural Heterogeneities in Southeast Tibet: Implications for Regional Flow in the Lower Crust and Upper Mantle

open access: yesInternational Journal of Geophysics, 2012
Our seismic study together with the MT analysis reveal a “R-shape” flow existing in both the lower crust and uppermost mantle, which suggests the crustal deformation along the deep, large sutures (such as the Longmen Shan fault and the Anninghe Fault ...

A comprehensive evaluation index for shale reservoirs and its application: A case study of the Ordovician Wufeng Formation to Silurian Longmaxi Formation in southeastern margin of Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2017
Aiming at the disadvantages of existing shale reservoir evaluation methods, a new comprehensive index was proposed to accurately predict the distribution of high quality shale reservoirs and favorable fracturing intervals.

Microstructure characteristics of Wufeng-Longmaxi shale gas reservoirs with different depth, southeastern Sichuan Basin

open access: yesShiyou shiyan dizhi, 2020
Thin section analysis, X-ray diffraction, conventional scanning electron microscopy (SEM), high-resolution Ar+ ion polishing SEM, mercury intrusion, nitrogen adsorption, total organic carbon (TOC) content and porosity analyses were used to determine the mineral composition, microstructure and micro-pore volume of shale reservoirs from different depths ...

Using Resistivity Structure to Study the Seismogenic Mechanism of the 2021 Luxian Ms6.0 Earthquakes

open access: yesRemote Sensing
Over the past few years, there has been a noticeable change in the occurrence of seismic disasters in Sichuan, China. The focus has shifted from Western Sichuan to the previously more stable Southeastern Sichuan.
