摘要: 将蒙特卡罗(Monte-Carlo)法引入煤层气资源量计算,可弥补容积法视各参数为常数的不足。重点论述了蒙特卡罗法用于煤层气资源量计算的主要算法和函数实现,包括参数选择、分布函数确定、伪随机数的产生以及对应伪随机数参数值的确定。利用上述算法自主开发了蒙特卡罗法软件。研究实例表明,在数据样本较多的情况下,该算法与容积法能保持较小误差范围且有更高的可信度。

Abstract: The Monte-Carlo method can resolve the problem that every parameter is often regarded as a constant during the process of calculating coalbed gas resource.This paper mostly describes the main arithmetic and functions realization in calculating coalbed gas resource by Monte-Carlo method,which includes parameter choice,definition of distribution function,generation of false random number and evaluation of the parameter corresponding to false random number.The Monte-Carlo software is programmed by above arithmetic and the software example shows that there is small difference in results between two methods,and Monte-Carlo method has more reliability.
