Evolution of Pore Connectivity in the Fushun Oil Shale by Low-Field Nuclear Magnetic Resonance Spectroscopy

open access: yesChinese Journal of Magnetic Resonance, 2019
During in-situ exploitation of the oil shale, the connectivity of the pore structure of the reservoir directly affects not only the flow behavior and heat transfer efficiency of the heat-carrying medium, but also the diffusion and flow behaviors of the ...

The monotonic behaviour of a low- to medium-density chalk through in-situ and laboratory characterisation [PDF]

open access: yesE3S Web of Conferences
Chalk is a highly variable cemented biomicrite limestone that can show widely different rock strengths and patterns of micro to macro fissuring and jointing, due to variations in depositional environments and local geological histories.

Nonlinear soil spring model and parameters for calculating deformation of enclosure structure of foundation pits

open access: yesYantu gongcheng xuebao, 2020
At present, when calculating deformation of foundation pits, it is unreasonable to use linear elastic spring to simulate the soil in the passive area. In order to make the calculation of foundation pit deformation closer to the actual monitoring results,
