TL;DR: In this article, the authors established an analytical model to study the influence mechanism of hydraulic fracturing around vertical wellbores under the unsteady seepage in hydrocarbon reservoirs, deduced the analytical solution of water pressure and hydraulic gradient of the model, and compared the law of hydraulic pressure and gradient changing with time with the results of numerical simulation.

TL;DR: In this paper, high-pressure fluid injection tests were used to investigate the variations in hydraulic properties of a fault zone at depth, and the analysis of experimental results showed that the injection rate and hydraulic conductivity increase as nonlinear functions of injection pressure.

TL;DR: In this paper, the variations in chromatic aberration, mass, P-wave velocity, porosity, thermal conductivity, and tensile strength of granite, sandstone, and marble induced by high temperature and chemical erosion are investigated from room temperature to 1000°C.

TL;DR: In this paper, in-situ strain tests were used to test the deformation and failure of the surrounding rocks and frequently associated with water-inrush through the mine floor.

TL;DR: In this paper, physical and thermophysical properties tests as well as Brazilian splitting test were conducted on red sandstone specimens after heating at a variety of different temperature and acidic solution erosion.
