摘要
首先运用技术经济学的有关原理,结合油藏工程原理的基本知识,建立了气藏储量初始经济产量的评价模型,得到了在不同天然气产量递减方式和不同内部收益率情况下的单井日产量,然后利用这些数据,运用SPSS软件进行了方差分析,得到了调和递减方式下的单井日产量与直线递减和凸型递减方式下的单井日产量有显著性差异的结论。最后通过SPSS软件对内部收益率、单井日产量、产量递减方式的回归,得到调和递减的效益好于指数递减;指数递减好于直线递减;直线递减好于凸型递减;并且单井日产量为气田效益影响的敏感因素的结论,为油气田经济评价方法提供一种思路。
The economic evaluation model of initial produc-tion of reservoir reserves was established by using economic princi-ple and combining the reservoir engineering knowledge,and the single well daily production was obtained under the condition of different production decline manner and different internal rate of return.Based on these data,the variance analysis was carried out by applied SPSS software,and the conclusion which single well daily production under harmonic decline manner and convexity de-cline manner has obvious difference was obtained.Through the re-gression of internal rate of return,single well daily production and production decline manner by using SPSS software,the conclu-sions which the benefit of harmonic decline is better than exponen-tial decline,exponential decline is better than straight - line de-cline,straight -line decline is better than convexity decline,were obtained.
