摘要
在探井岩心分析与测井解释资料基础上,结合波速机理分析,提出砂泥质岩波速的二级近似式;并将时间平均方程由二元推广到三元,可同时求取砂质岩的泥质分量和孔隙率。文中给出了在塔里木盆地储层研究中的应用实例。
Two-step approximate formula of seismic velocity in sand and shale formation is given on the basis of core analysis.logging data interpretation and wave velocity mechanism analysis.Time average equation in two element medium is extended into three element medium,so that both sand/shale ratio and porosity can be calculated successfully.A case study of reservoir in the Tarim basin is presented in the article.
