Using its probability statistical approach , this paper analyzes the uncertainty distribution of net pay thickness and permeability in the reservoir , researches the impart of geologic parameter uncertainty on gas well binomial productivity equation 应用概率统计法，分析了储集层有效厚度、渗透率的不确定性分布，研究了地质参数不确定性对气井二项式产能方程的影响。
Abstract : this paper introduces a method for determining average formation pressure in homogeneous gas wells and gas wells with boundary and formation heterogeneity , checked by actual measured pressure value , this method is proved to be simple and effective 文摘:本文介绍了均质及存在边界或地层非均质气井平均地层压力的确定方法，经实测压力值检验，证实方法是简易有效的。
Because the anisotropism of the reservoir is severeness , there are no nature gapping , the reserves abundance is low and the well has no nature off - take potentia , this gas pool is a low permeability , low abundance , deadly low production , low grade complex pool 因储层非均质性严重，无天然气裂缝，储量丰度低，气井无自然产能，又属于低渗低丰度，特低产、低品位复杂气藏。
