Studying the impacts of varying unloading speeds on their strain energy (SE) density is highly significant for predicting rock stability. Through true triaxial unloading principal stress experiments and true triaxial stress equilibrium unloading experiments on sandstone, this paper proposes a method to ...

There are abundant tight sandstone gas resources in the Sichuan Basin, which are the important objects of reserve and production increase and large-scale development. Due to their discontinuous sandbody distribution, narrow channels, and strong horizontal and vertical heterogeneity, however, conventional ...
Based on the compaction model of sandstone mudstone alternating beds, we advance a new formula forformation grain density, which conforms to grain volume and mass balance law. 提出一种新的地层骨架密度计算公式。 5) catalyst skeleton density
If it is a regular shape, the volume can be directly measured; if it is in an irregular shape, the volume can be measured by the liquid drainage method after sealing pores with wax; the liquid drainage method can be directly used to measure the volume of sandstone aggregate utilized in ...

This method is designed for oddly shaped samples of at-least-somewhat-consolidated material—for example, glacial till, compacted loess, saprolite, cemented sand, sandstone, shale. The procedure is as follows: 1. From the top left drawer in the sediment lab, select a stainless-steel tin slightl...
Relation between crack density and acoustic nonlinearity in thermally damaged sandstone. Int. J. Rock Mech. Min. Sci. 125, 104171. https://doi.org/10.1016/j.ijrmms.2019.104171 [33] Kingma, D.P., Ba, J., 2014. Adam: A method for stochastic optimization. arXiv: 1412.6980v9. [34] ...
Particles more irregular in shape tend to have larger gaps between their nontouching surfaces, thus forming media of greater porosity. In porous rock such as sandstone, cementation or welding of particles not only creates pores that are different in shape from those of particulate media, but also...
