fracture system裂隙系统
1.The purpose of this research is to investigate the properties of pore-fracture system and to reveal the relationship between the physical properties of coal reservoirs and recovery of coalbed methane in Huainan and Huaibei coal-fields.借助于光学显微镜显微裂隙分析、压汞孔隙分析及低温氮吸附试验等手段,研究了两淮煤田煤储层孔、裂隙系统发育情况。
2.There exist lots of factors influencing the differencial distribution of permeability,from such aspects as the development of fracture system,the effective stress of coal-bed reservoirs,coal-bed tectonic evolution and coal-bearing rock metamorphic degree,the relationship among them and spacial distribution of highly permeable areas and the research progress are illustrated.煤储层渗透性是制约煤层气勘探选区的重要参数,影响渗透率差异分布的因素有很多,从裂隙系统的发育、煤储层有效应力、煤层构造演化、煤岩变质程度几个方面阐述了它们与高渗区空间分布的关系及其研究进展。
3)joint system裂隙系统
1.Based on the analysis of nonlinear dynamics to time series of strain and stress which are tested by MTS to lots of joint systems of sandstone specimens,a new rule to find the largest Lyapunov exponent is established by introducing LE1-m mathematical model and unit-step function.基于对大量砂岩试样裂隙系统的MTS全应力–应变时间序列的非线性动力学分析,构造单位阶跃函数并引入到最大Lyapunov指数LE1的判别模型中,建立了确定LE1的新准则。
4)the pore-fracture system孔裂隙系统
1.The pore-fracture system, permeability of the coal reservoir and the heterogeneity of the pore-fracture system and permeability are very important aspects of the coal reservoir evaluation .煤储层研究的重要内容是孔裂隙系统发育特征、渗透性及其空间不均一性特征。
5)pore-fracture system孔隙、裂隙系统
1.The pore-fracture system consists of pore,microfracture,cleat and joint.煤储层孔隙、裂隙系统由孔隙、微裂隙、内生裂隙和外生节理组成。
6)coal reservoir fracture system煤储层裂隙系统
