沁水盆地南部地区煤层气储层岩石物理实验
Rock Physical Parameters of Coal Reservoir in the South of Qinshui Basin
摘要
Abstract
It is the key to realize the efficient evaluation of coalbed methane reservoir that studied the petrophysical characteristics of coalbed gas,and serach for scientific calculation model of reservoir parameter.The coal in the south of Qinshui basin are taken as the object of study for the first time,the line cutting technique has been used to obtain the plunger core for rock physics experiment,and the physical properties and acoustic parameters of coalbed methane reservoir under different temperature and pressure are systematically studied:the southern Qinshui basin coalbed gas reservoir porosity and permeability have reached the class I reservoir evaluation standard,but strong heterogeneity leads to changes in the scope of coal reservoir permeability is larger,part of the region has the characteristics of low permeability and low permeability layer;the pore structure of reservoir in southern Qinshui basin area is complicated,mainly with micro pores and small pores;there is a good linear relationship between the shear wave velocity of coalbed gas reservoir layer,known in coalbed gas reservoir under the condition of P-wave velocity,S-wave velocity prediction of coalbed gas reservoir through the relationship between shear wave velocity,and the relationship between velocity and density and between the shear wave velocity relationship can study the changes of lithology and gas bearing forecast.关键词
