摘要

通过分析方法(体积法、物质平衡方程和递减曲线分析)确定煤层气储层的储量估算。然而,储量估算方法的采用取决于勘探阶段和所需参数的可用性。本研究通过分析技术对参与煤层气储层储量估算的参数进行分析评估。由于测量时存在局限性,参与常规和非常规储层储量估算的参数始终存在精确测量的挑战。因此,必须评估这一衡量挑战的影响。该研究规定了参数变化对煤层气储层储量估算的影响,从而分析了参数有效性的程度。在评估每种方法的输入参数时,采用了不确定值,以确定对煤层气储量潜力的总体影响。结果表明,考虑每种方法的特定参数的变化对储量估计的影响相对较大。因此,必须准确测量参数,以便根据现有方法评估煤层气储层的储量。

Assessment of parameters effectiveness in the reserve estimation methods applicable to coal bed methane reservoirs

The reserve estimation of coal bed methane (CBM) reservoirs is ascertained through the analytical methods (volumetric method, material balance equation and decline curve analysis). However, the adoption of reserve estimation methods depends on exploration stage and availability of the required parameters. This study deals with the analytical assessment of parameters that participate in effecting the reserve estimation of CBM reservoirs through the analytical techniques. The accurate measurement challenges always exist for the parameters which participate in the reserve estimation of the conventional and unconventional reservoirs because of the inclusion of limitations while measurement. Therefore, the impact of that measurement challenge must be assessed. The study specifies the impact of parametric change on the reserve estimation of CBM reservoirs so that the degree of parametric effectiveness is analyzed. Uncertain values are adopted which are associated during the evaluation of input parameters for each method to determine the overall impact on potential of CBM reserves. Results reveal that change in specific parameters considering each method provide relatively more effect on estimation of reserves. Thus, the measurement of parameters must be done accurately for assessing reserves of CBM reservoirs based on available methods.
