Zhong Zulan and Ling Shuopel. Study on Median Radius of Rocks Using Well Logs

在分析岩心孔隙结构参数特点的基础上,讨论了用测井方法研究岩石孔隙结构参数的必要性。建立了用测井资料计算孔喉中值半径的方程,该方程中的参数可用声波时差、自然伽玛及深侧向电阻率求得。还讨论了影响孔喉中值半径的因素。最后给出了实例。

Based on analysis of the parameters of core pore structure, this paper discusses necessity to study thepore structure parameters from well logs. The equations of computating the median radius of pore throatusing well logs are presented. The parameters in the equations can be obtained from acoustic, gamma-raylogs and deep laterolog. The factors of effect on the median radius of the pore throat are also desribedFinally, the examples are given.
