摘要： 气井产能评价是确定无阻流量和工作制度、预测生产动态及其它气藏工程研究的重要手段。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。实例计算表明,考虑地质参数的不确定性能够使气井产能评价更准确,并能降低气藏开发存在的风险。

Abstract: Gas well productivity estimation is an important method for determination of open flow potential and working system, prediction of production performance and study of related gas reservoir engineering. Using its probability statistical approach, this paper analyzes the uncertainty distribution of net pay thickness and permeability in the reservoir, researches the impact of geologic parameter uncertainty on gas well binomial productivity equation. Case study shows that considering the geologic parameter uncertainty allows the gas well productivity estimation to be more precise, thus decreasing the possible risks in gas pool development.
