摘要
碳酸盐岩地层的测井流体识别是石油测井数据处理与解释的重要内容和难点.本文基于Gassmann等效介质理论和流体替换基本原理,详细研究了基于测井数据和评价结果的流体替换方法,实现步骤和流程.针对塔河油田奥陶系地层,利用测井资料和试油资料,应用该流体替换方法和流程分别进行了饱含水、饱含气和饱含油的流体替换,根据流体替换前后的密度、速度以及体积模量等岩石物理参数的变化,实现了碳酸盐岩地层的流体识别.
Fluid identification from well logging in carbonate formation is an important and difficult problem in logging data processing and interpretation. The basic principle of fluid substitution based on Gassmann effective media theory is studied in detail,and the method and procedure of fluid substitution based on logging data and log evaluation parameters are also formed.Pointing to Ordovician formation of the Tahe Oilfield,the fluid substitution theory is applied to fluid typing with logging data and testing data,in which the fluid substitutions tests are carried out by saturated water,saturated oil and saturated gas.According to difference of some rock physical parameters between before and after substitution,the fluid typing is achieved successfully in the carbonate formation.
