摘要

储层物性一般服从正态分布。以往对储层物性分布的评价普遍采用对数正态概率纸或正态概率纸方法进行。该方法存在着两点不足:一是受物理条件限制较大,当缺少正态概率纸时,难以应用此法;二是该方法仅能手工读数,难以计算机处理,计算的精度较差。通过对正态分布函数的研究,提出了一种新的统计方法,在计算机上用Excel办公软件就可完成对储层物性参数分布的统计分析。实例应用证明,新方法使用方便,结果可靠。

Abstract

The distribution of reservoir properties is commonly subjected to normal probability. There are two disadvantages in the traditional method to study reservoir properties distribution by logarithm normal probability sheet or normal probability sheet: one is, when normal probability sheet is unavailable the method will not work; the other is, reading by handcraft leads to poor accuracy. In using of normal distribution function, this paper puts forward a new method to study the distribution of rock properties by using the Microsoft Office Excel software on computer. The study in case proves that the new method is convenient and the result is credible.
