分布函数曲线法是一种确定储集层物性参数下限的新方法。该方法从统计学角度出发，通过有效含气层与非有效含气层样本分布函数曲线之间的关系确定储集层物性参数下限值，在鄂尔多斯盆地中部气田的实际应用中，效果较好，与采用产能系数法、经验统计法及油田实验测试相比较，得到的结果基本一致，表明这一方法值得进一步推广使用。
Distribution function curve method is a new method to determine the lower limit of reservoir physical parameters. Based on the statistical analysis, the method determines the lower limit of physical property parameters through the relationship between the distribution curve of effective gas-bearing and non-effective gas-bearing samples. The method has a good effect in the practical application of the gas field in the central Ordos Basin Compared with the method of productivity coefficient, empirical statistics and field test, the obtained results are basically the same, which shows that this method is worth to be further popularized.
