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
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
through sy...
Investigation on Coal Skeleton Deformation in CO2 Injection Enhanced CH4 Drainage From Underground Coal Seam
Frontiers in Earth Science - Tập 9
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.
Meanwhile, numerical simulations were carried out by implementing the
mathematical model in the...
Fractal characteristics and theirs influence on methane adsorption in high-rank coals with NMR
Frontiers in Earth Science - Tập 10
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 magnetic resonance (NMR), we obtained the
fractal ...

Mẫu Thông Tin Khí Hậu Cổ Chi Tiết Cho Lưu Vực Trung Danube Trong 430 ngàn Năm Qua: Nghiên Cứu Từ Tính Chất Đá-Magnesium Và Phân Tích Màu Của Chuỗi Loess-Paleosol Zemun Dịch bởi AI
Frontiers in Earth Science - Tập 9
Tại khu vực trung latitudes của Eurasia, các chuỗi loess-paleosol (LPS) cung cấp
các hồ sơ trầm tích phổ biến nhất về sự phát triển của môi trường khí hậu trong
thời kỳ Đệ Tứ. Tại lưu vực Trung Danube (MDB), các tài liệu này bao gồm ít nhất
một triệu năm lịch sử khí hậu, và đôi khi chứa các phát hiện khảo cổ. Chuỗi
Zemun LPS được nghiên cứu nằm ở bờ phải của sông Danube tại miền Bắc Serbia. Địa

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
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. Based on the data from molecular
components...
