摘要
为了精确地确定乌尔逊地区凝灰质砂岩的骨架值,运用岩心分析资料与测井资料,采用5种不同的方法分别求得中子、声波、密度骨架参数。再利用所求取的骨架值计算孔隙度,根据计算孔隙度值与岩心分析孔隙度之间的平均绝对误差与相对误差,选取最小值以确定最优的骨架参数值,从而找到适合研究区的确定骨架参数的最佳方法。这为凝灰质砂岩储集层的正确评价提供了较好的依据和参考。
The essay aiming at the tuffaceous sands reservoir of Wuerxun area defines framework parameter of neutron-density-sonic by five methods with the core analysis porosities data and logging data to explore better method of defining framework parameter.The essay calculates porosities with framework parameter that were defined by different methods,and defines the best framework parameter according to the meanabsolute and relative error of the core analysis porosities and calculated porosities.So it defined the best method of calculating framework parameter to offer the foundation and reference for evaluating the tuffaceous sands reservoir.
