摘要
表征沉积岩所含有机质丰度的数据,特别是有机碳丰度实测数据和氯仿沥青丰度实测数据,是石油地质工作者经常用到的数据。目前人们对这些数据的统计和应用,主要采用个别值法、平均值法、数值区间法和正态分布法,这四种方法在不同程度上均不甚完善,现简述如下。
Abstract
It is shown by experience that the abundance of organic matter in inorganic rocks accords with the Γ-distribution,which is denoted as:where y is the probability density,x the organic matter abundance,6 the the minimum value of x,and a and β the parameters determining the patterns of the distribution curve,respectively.When the mean value of samples x and the standard deviation S are obtained,a and β can be defined by.
