Numerically investigating the crushing of sandstone by a tooth hob

Frontiers of Structural and Civil Engineering Pages 964-979 doi: 10.1007/s11709-023-0978-6

Abstract: To investigate the mechanical process that occurs between rocks and tooth hobs, the crushing of sandstonewas simulated using reconstructed multi-mineral mesoscopic numerical models of various grain-sized sandstoneWhen a piece of sandstone is crushed by the tooth of a hob rolling at a constant speed, the resultantreaction forces of the sandstone on the tooth first hinder and then contribute to the rolling of theBecause the tooth was subjected to reaction forces from the sandstone, forces and moments were applied

Resource evaluation，position and distribution of tight sandstone gas in China

Zhang Guosheng ,Deng Songtao

Strategic Study of CAE 2012, Volume 14, Issue 6, Pages 87-93

Abstract:

Based on the reservoir forming condition research of tight sandstonegas in Ordos Basin, Sichuan Basin and Tarim Basin, the authors give two types of tight sandstone gasreservoirs,sloped lithologic type and structural type which are the main of tight sandstone gas reservoirAnd based on the existed tight sandstone gas reservoir analysis, the authors get the main parametersThe tight sandstone gas is the most realistic source in present.

The exploration of global tight sandstone gas and forecast of the development tendency in China

Yang Tao,Zhang Guosheng,Liang Kun,Zheng Min,Guo Bincheng

Strategic Study of CAE 2012, Volume 14, Issue 6, Pages 64-68

Abstract: Especially the large-scale exploration and utilization of American tight sandstone gas promotes the exploration& development in other countries.Based on a brief overview of global tight sandstone gas explorationhistory, the exploration effect as well as the development tendency and proposals of China's tight sandstonethree stages and is entering the fast-developing stage recently.In recent years, several large tight sandstonenature gas production in 2011, and it is predicted to reach 1/3 in 2020, and at that time the tight sandstone

Comparison study on accumulation & distribution of tight sandstone gas between China and the United States

Tong Xiaoguang,Guo Bincheng,Li Jianzhong,Huang Fuxi

Strategic Study of CAE 2012, Volume 14, Issue 6, Pages 9-15

Abstract:

The tight gas has already been the important field of the global unconventional resource exploration. The distribution of tight gas in China is very wide; for example, the scale development of Ordos Basin and Sichuan Basin have been achieved. The Rokey Mountain in the United States is the area where the tight gas is well developed. Comparative study on the generation condition and reservoir characters of American tight gas is the useful way to accelerate the development of tight gas and open up the thought of exploration. The result of comparative analysis of tight gas reservoir between China and the United States shows: tight gas of China and the United States havs many common characters, for example, most source rock being coal measure strata, tight reservoir, abnormal formation pressure, resource and reservoir intimate contract and gas reservoir gross distribution and so on; otherness is mainly reflected in tight gas source depositional environment,thermal evolution extent, reservoir heterogeneity, densifying factor, the longitudinal and plane distribution characteristics of gas reservoir. The main factors of are the character of depositional basin, sedimentary environment and deuterogene tectonic feature. In allusion to the particularity of Chinese tight gas, the key points of tight gas exploration and development are intensifying reservoir heterogeneity, high grade reservoir forecast, and the study of gas reservoir distribution and striving to make technological breakthrough to increase well cumulative production.

Experimental investigation on strength of sandstone weathered and absorbed water heavily and its constitutive

Zou Chong,Lei Shengyou,Yue Xijun,Song Yan,Gao Pan

Strategic Study of CAE 2011, Volume 13, Issue 1, Pages 74-80

Abstract:

According to the feature of sandstone weathered and absorbed water heavily, the authors analyzed the physical and mechanical properties and chemical composition of the sandstonestress-strain strength characteristics through uniaxial and triaxial compression tests, and found that the sandstoneAfter the sandstone underwent blasting, its uniaxial compressive resistance and elastic modulus decreasedAs the sandstone has obvious bedding properties, the strengths of sample obtained from two different
