泥质砂岩储集层岩心分析孔隙度与声波时差关系探讨

An Approach to the Relationship between Core Sample Porosity and Acoustic Log Time Interval in Shaly Sand Reservoirs

本文针对利用岩心分析孔隙度与声波时差建立经验关系时存在的问题,提出了改进方法。本文建议的方法,减少了由于岩心分析方法所造成的孔隙度误差,具有一定的实用价值。

This paper analyses the problems in establishment of the relationship be-tween core sample porosity and acoustic log time interval and proposes anim-proved core sample measuring method, which reduces core sample porositymeasurement errors. This method is useful and practical.
