摘　　要：运用技术经济的基本原理,建立了低渗透气藏储量最优经济评价模型,为低渗透气藏储量经济评价提供一种简便的方法。首先,建立经济评价模型。模型建立的思路为:将收益和支出均折算为初始年份(气田产能建设完成,正式投产)的现值。然后,根据模型的数学方程推导出关于内部收益率与单井日产量和井深的方程式。根据油田实际情况及相关文献,确定已知的评价参数。利用SPSS软件对随机测得的数据进行回归,得到内部收益率与单井日产量和井深的具体数值方程。数值方程显示:内部收益率与井深成负相关关系,与单井日产量成正相关关系。通过该方程,即可根据已知井区的单井日产量、井深数据,求得相应的内部收益率。影响内部收益率的单因素敏感性分析显示:天然气价格为最敏感因素,其后依次是单井日产量、钻井成本和井深,最不敏感的因素为地面建设投资和操作成本。Basic principle of technology economy was applied for building optimizing economic evaluation model of low permeability gas reserves,and it is a simple method.The first step was to establish economic evaluation model.Profit and payment were converted as present value in initial year.Then,according to mathematics equation of the model ,an equation of internal returns ratio and daily production of single well and well depth was derived.Evaluation parameters were determined according to the actual situation and relevant references.Random measured data is regressed nal returns ratio and the daily production of using SPSS software,and the mathematical model among intersingle well and the well depth was obtained.h shows negative correlation between internal returns ratio and well depth ,and positive correlation between interval returns ratio and daily production of single well.The internal returns ratio can be solved through this equation.The influencing factors of it are the sensitive natural gas price ,and then daily output, drilling cost and well depth, and the less-sensitive surface construction investment and operation cost.
