SEC准则下基于R3软件的煤层气、致密气上市储量评估方法初探

Preliminary Study on Reserves Evaluation of Coalbed Methane and Tight Gas Based on R3 Software under SEC Rule

为合理评估煤层气、致密气资产价值,本文基于R3评估软件,以沁水盆地潘河、寿阳南燕竹煤层气区块、临兴中致密气区块为案例,对不同类型的煤层气藏、致密气藏上市储量评估提出了相应的评估思路和方法。研究结果表明:煤层气、致密气藏SEC储量评估主要包含三大步骤:一是确定储量级别,二是计算单井技术可采储量,三是经济评价。煤层气藏的评估主要采用动态法、静态法及概率法;致密气藏的评估主要采用动态法和概率法。

In order to evaluate the value of CBM and tight gas assets, using R3 and taking Panhe, Shouyang South Yanzhu and Linxing Middle Blocks as cases, this article puts forward corresponding evaluation ideas and methods for evaluating the listed reserves of different types of CBM and tight gas reservoirs. The results show that SEC reserves assessment of CBM and tight gas reservoirs mainly contained three steps: first, to determine the category of reserves;second, to calculatethe technically recoverable reserves per well;third, economicevaluation. The assessment of CBM reservoir mainly adopts dynamic method, static method and probabilistic method.
