一种新的声波孔隙度计算方法——声波孔隙度同态解释系统已经研制出来。它仅通过几块岩芯样品的孔隙度分析值,就能求准整个井的孔隙度。非取芯井的孔隙度能使用邻近井的反褶积因子确定,精度不低于数理统计方法的结果。本文讨论了该系统的原理和结构,给出了取芯井和非取芯井的应用实例。

A new method of determining acoustic porosity, which is termed the Acoustic Porosity Homomorphic Interpretation System has been successfully developed. The correct porosity could be ensured throughout a well just by merely setting the porosity analytic value of few core samples. The porosity of non -coring well can be determined using the deconvolu-tion factors of its adjacent coring wells. And its accuracy turned out does come up to that done through the mathematical statistics method. The concept and configuration of the system are discussed. And examples from both coring well and non -coring well are given.
