Water sealing performance is important for underground water-sealed oil storage (UWSOS).
The key issues concerning water sealing performance mainly include the permeability of …

As the underground water-sealed storage is one of the important ways of oil and other
energy storage in China, the development and innovation of basic theory and key …

Modeling saturated-unsaturated flow in fractured rock formations remains a challenging
issue due to the difficulties in properly calibrating the unsaturated flow properties for …

A systematic approach has been developed to estimate the relationship between the
permeability and connectivity of two‐dimensional fracture networks, in which the network …

We present a numerical analysis on injection-induced crack propagation and coalescence
in brittle rock. The DEM network coupling model in PFC is modified to capture the evolution …

Modeling unsaturated flow in fractured rocks is essential in various subsurface engineering
applications, but it remains a great challenge due to the difficulties in determining the …

The impacts of rheological properties of cementitious grouts on the quality of curtain and
consolidation grouting cannot be ignored. A series of experiments are carried out to …

Soil enzyme activities and microbial communities have a good response to the remediation
effect of heavy metal-contaminated soils. To evaluate the effect of three commonly used …

The normal stress-dependent hydraulic properties of single fractures are fundamental in
hydro-mechanical coupling for the fractured reservoirs. With increasing normal stress, fluid …

This work adopts the ISPH method for handling the impact flow of a circular cylinder over a
free surface flow saturated by the porous media. The novelty of this work is simulating the …
