Mechanisms of helium differential enrichment and helium‐nitrogen coupling: A case study from the Weiyuan and Anyue gas fields, Sichuan Basin, China

Geological Journal, Volume 59, Issue 1, Page 272-287, January 2024.
The uplift of the basement granite was crucial for the exsolution and enrichment of dissolved helium, and it was also the main reason for He–N2 coupling. The differential uplift that occurred in the Leshan–Longnvsi palaeo‐uplift during the Himalayan period further promoted the differential enrichment of He resources, thus also impacting the N2/He ratio

Comparative Analysis of Shale Gas Enrichment and High Yield Geological Conditions of Wufeng–Longmaxi Formation and Qiongzhusi Formation in Southern Sichuan Basin

Geofluids, Volume 2024, Issue 1, 2024.
Wufeng–Longmaxi Formation and Qiongzhusi Formation are the significant shale gas exploration strata in China. The former has made a major breakthrough, and the exploration of the latter is restricted. At present, it shows good exploration potential in the Qiongzhusi Formation.

A Case Study on Preservation Conditions and Influencing Factors of Shale Gas in the Lower Paleozoic Niutitang Formation, Western Hubei and Hunan, Middle Yangtze Region, China

Geofluids, Volume 2024, Issue 1, 2024.
The Niutitang Formation of the lower Cambrian (Є1n) is a target reservoir of shale gas widely developed in China’s Middle‐Upper Yangtze region, with the characteristics of being widely distributed, having a big thickness and highly organic carbon abundance. However, the exploration and research degree are relatively low. Based on extensive core sample,

The bitumen development effect on the pore structure and electrical resistivity of carbonate reservoirs in the Sinian Dengying Formation

Journal of Geophysics and Engineering
Abstract In the Sichuan Basin, bitumen widely distributes in the carbonate reservoir, and the bitumen occurrence morphology affects the pore structure and petrophysics. Two types of bitumen, boundary-filled and centre-filled, were reconstructed using a pore morphology-based method based on dolomite carbonate digital cores from X-ray ...

Application of New Techniques for Fracture-Vug Effictiveness Analysis Based on Micro Resistivity Imaging Logging in the Dengying Formation

, 2023
The secondary pores occurred in post-sediment deposition are very heterogeneous in the Sinian Dengying carbonate formation of Gaoshiti-Moxi area in Sichuan basin, which has caused significant test production differences.

History of hydrocarbon accumulations spanning important tectonic phases and its hydrocarbon differential accumulation of Sinian Dengying Formation in Sichuan Basin

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Sichuan Basin has undergone three stages of important tectonic events at the end of Early Paleozoic, Late Paleozoic-Early Mesozoic, and Late Cenozoic. These tectonic events have put strong influence on hydrocarbon generation, migration, accumulations of Sinian Dengying Formation.
