Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

Deep Underground Science and Engineering, EarlyView.The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

Geophysical Research Progress On Tight Sandstone Reservoir In Sulige Gas Field
Improved Oil and Gas Recovery, 2020 The tight sandstone reservoir in the cooperation block of Sulige gas field is characterized by thin gas-bearing sand, large variation laterally, and strong heterogeneity. Due to the complex surface conditions, and particularly the thick weathered zone, the 3D seismic data presented limited frequency bandwidth.

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...
