| 摘 要： | 根据研究区56口井,笔者对岩心、自然伽马、自然电位、声波时差、密度、中子等钻井、测井资料进行多种统计和交会分析,研究速度、密度、波阻抗、孔隙度与深度、岩性,波阻抗与孔隙度等的关系,分析储层物性特征,并作相关交会图,建立规律关系式。经比较得出利用波阻抗进行下一步的反演工作会比较合理。根据砂岩孔隙度与波阻抗之间的函数关系,可以利用砂岩波阻抗估算砂岩孔隙度。为下一步储层预测研究提供良好的基础资料。

| Abstract: | This paper collects various logging data of core,natural gamma,spontaneous potential,acoustic travel time,density,neutron etc.and tries to study the relationships of the speed,density,wave impedance and porosity with the depth,lithology,as well as the relationships between wave impedance and porosity.Then it analyzes the characteristics of the reservoir forecast.Through comparison,it is reasonable to go on with the next inversion task by using wave impedance.Based on the relationship between sand porosity and wave impedance,we can use the sand wave impedance to estimate the sand porosity.This study provides very good information for the reservoir predict research. |
