摘　　要：基于柿庄南区块3~#煤层构造特征,结合测井资料和GSI多参数拟合,通过煤层构造曲率和渗透率的统计分析,定量研究煤储层构造对渗透率的控制关系。研究表明:煤储层构造曲率介于(0.3～2)×10^(-4)/m时,渗透率均大于0.2×10^(-3)μm^2;构造曲率低于0.3×10^(-4)/m或者高于2×10^(-4)/m时,煤储层渗透率均小于0.2×10^(-3)μm^2。煤储层构造曲率过高或过低都不利于渗透率的提高,以中等为好。Based on the structural characteristics of No. 3 coal seam in the southern Shizhuang area,combined with logging data and GSI multi parameter fitting, the relationship between coal reservoir structure and permeability is quantitatively studied through the statistical analysis of the curvature and permeability of the coal structure. The research shows that when the structural curvature of coal reservoir is(0.3~2)×10-4/m, the permeability is greater than 0.2×10-3μm2, and when the structural curvature is below 0.3×10-4/m or higher than 2×10-4/m, the permeability of coal reservoir is less than 0.2×10-3μm2.The high or low structural curvature of the coal reservoir is not conducive to the improvement of permeability, and the medium is good.
