摘要
对火山岩储层应用三孔隙度模型计算随孔隙成分变化的胶结指数,与岩电实验结果对比,讨论了岩电实验胶结指数与三孔隙度模型计算的胶结指数之间存在误差的可能原因。研究表明,三孔隙模型计算的随孔隙成分变化的胶结指数能较好地反映地层孔隙结构的变化,与普通岩电实验数据对比有一致性,为三孔隙度模型在火山岩储层评价中的应用提供了依据。
The cementation exponent（m） is the measurement of formation＇s conducting channel curvature,which presents the formation pore space geometry.In this paper,calculated is m with the pore component changes by triple porosity model in volcanic reservoir,and then the results are compared with the petrophysical data.Discussed are the possible reasons for the errors between the model results and the petrophysical data.Results show that the cementation exponent calculated by triple porosity model can presents the changes of formation pore structures.Comparing with petrophysical experiment data,the two results have consistency.The results provide a reliable basis for the application of triple porosity model in volcanic reservoir.
