摘要: 考虑了高压和储集层岩石应力敏感性对超高压气藏产能的影响,推导了新的产能方程,基于该方程研究了产能方程系数及绝对无阻流量的确定方法。结合几口超高压气井的实际产能测试数据,进行了实例应用并对产能评价结果进行了分析。研究表明:考虑应力敏感性时所获得的气井绝对无阻流量要比不考虑应力敏感性时减小10%~25%,并与不考虑应力敏感性时压力平方方法所获得的绝对无阻流量相当。

Abstract: The effects of high pressure and reservoir rock stress sensitivity on super-high gas reservoir productivity are considered, the new productivity equations are deduced and the method for determination of the coefficient and the absolute open flow potential or deliverability are presented. Field application and appraisal result show that the deliverability given by this new method is 10%~25% lower than that by the conventional method, but comparable with that by pressure-squared method without regard to the stress sensitivity. This paper suggests that when making productivity appraisal of super-high pressure and stress sensitivity gas reservoir during early phase of exploration or development, the pressure-squared method can be used to approximately determine the absolute open flow potentials of gas reservoirs.

Key words: high pressure gas reservoir, stress sensitivity, productivity prediction, open flow potential, deliverability, appraisal, evaluation
