Influence of tight sandstone gas in roof on gas production in deep coalbed methane wells: A case study of Shenfu block in Ordos Basin [PDF]

Youqicang pingjia yu kaifa
In the Shenfu block located on the eastern margin of the Ordos Basin, the deep coal seam is intimately interlayered with the tight sandstone layer. During the development of deep coalbed methane, a notable phenomenon has been observed whereby tight ...

Study on seepage characteristics of tight sandstone reservoir

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Seepage characteristics of reservoir rocks are important factors affecting the effect of tight oil and gas production. Therefore the pore structure of tight sandstone from Dong 6 well in 4 block of the central Dzungaria Basin were studied by mercury injection experiment, and the seepage characteristics of tight sandstone were ...

Tight sandstone reservoir sensitivity and damage mechanism analysis: A case study from Ordos Basin, China and implications for reservoir damage prevention

Energy Geoscience, 2022
Analysis of reservoir sensitivity to velocity, water, salt, acid, alkali and stress is critical for reservoir protection. To study the tight sandstone reservoir sensitivity at different formation depths (effective stress) and formation water conditions ...

Forced imbibition in tight sandstone cores

Shiyou shiyan dizhi, 2021
Spontaneous imbibition (SI) generally occurs under forced pressure (pressure difference between hydraulic fluid pressure and original pore pressure) during a shut-in period. However, the experimental study of SI is commonly performed at atmospheric pressure and the effect of forced pressure is often neglected.

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.
