Resistivity correction and water saturation evaluation for calcareous tight sandstone reservoir: A case study of G oil field in Sichuan Basin
Frontiers in Earth Science - Tập 10
Yukui Zhang, Jun Jia, Hua Hu, Yao Du, An Hongyi, Fang Shi
The calcareous tight sandstone reservoir of the Triassic Shaximiao Formation in the G oil field of the central Sichuan Basin has high calcium content and abnormally high resistivity, making it difficult to reveal the oil-bearing property, evaluate water saturation, and calculate geological reserves. In this work, a petrophysical volume model of calcareous tight sandstone was established th...... hiện toàn bộ
Investigation on Coal Skeleton Deformation in CO2 Injection Enhanced CH4 Drainage From Underground Coal Seam
Frontiers in Earth Science - Tập 9
Chaojun Fan, Lei Yang, Gang Wang, Qiming Huang, Xiang Fu, Haiou Wen
To reveal the evolution law of coal skeleton deformation during the process of CO2 flooding and displacing CH4 in coal seam, a fluid-solid coupling mathematical model of CO2 injection enhanced CH4 drainage was established based on Fick’s law, Darcy’s law, ideal gas state equation, and Langmuir equation.

Fractal characteristics and theirs influence on methane adsorption in high-rank coals with NMR
Frontiers in Earth Science - Tập 10
Wei Jiang, Ying Zhou, Caifang Wu, Mingyang Du
To further understand the pore structure characteristics and their effect on CH4 adsorption capacity for high-rank coals. Based on 11 fresh coal samples from the Zhina coalfield of South China. We analyzed the pore structure characteristics of coal samples by low-temperature liquid-nitrogen adsorption (LP-N2A) measurements. On the basis of nuclear ...... hiện toàn bộ

The Effect of Thermochemical Sulphate Reduction on the Carbon Isotope Ratio of Individual Light Hydrocarbons Associated With Natural Gas
Frontiers in Earth Science - Tập 10
Guoyi Hu, Jinhao Guo, Lianjie Tian, Xiaoqi Wu, Jin Su, Zhisheng Li, Chenchen Fang
To understand the effect of thermochemical sulphate reduction (TSR) on the stable carbon isotopes of light hydrocarbons (LHs) associated with natural gas, 15 gases with varying H2S content from Ordovician reservoir of the Tazhong gas field (TZ-I) in Tarim Basin and Triassic Leikoupo reservoir of the Zhongba gas field (ZB) in Sichuan Basin were collected.
