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.

When the Great Equalizer Shuts Down: Schools, Peers, and Parents in Pandemic Times [PDF]
SSRN Electronic Journal, 2020 What are the effects of school closures during the Covid-19 pandemic on children's education? Online education is an imperfect substitute for in-person learning, particularly for children from low-income families. Peer effects also change: schools allow children from different socio-economic backgrounds to mix together, and this effect is lost when ...

Design and Research of Mechanical Gas Timing Shut-off Device [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 Abstract With the generalization of the use of gas and natural gas, the design and research of the timing shut-off device for gas has become an indispensable factor to avoid gas poisoning incidents. In order to solve such problems, this paper proposes a mechanical gas timing shut-off device design, expounds the operation principle of the

Application of digital rock technology for formation damage evaluation in tight sandstone reservoir
Journal of Petroleum Exploration and Production Technology, 2022 Formation damage is a common phenomenon and is impaired to the reservoir by reducing the productivity. Formation damage is usually caused by solids plugging, clay swelling, saturation changes, etc., and fracturing fluids with a series of chemical ...
