摘　　要：国内煤层气田上市储量评估多以区块为评估单元,采用动态法评估,历次评估结果之间相差较大。通过分析柿庄南区块煤层气生产特征及产能主控因素,总结典型井生产规律及关键参数,在此基础上,提出了以单井为评估单元,动态法与体积法相结合的精细评估思路与方法,实践应用表明该方法成功解决了开发中期煤层气田储层物性及生产特征差异大的问题,确保了评估结果的合理性。The listed reserves evaluation of coalbed methane fields normally takes blocks as the evaluation unit and adopts the dynamic evaluation method,while there are usually significant differences in multiple evaluations.By analyzing the production characteristics and main factors controlling the productivity of coalbed methane in Shizhuang South Block,summarizing the production rules and key parameters of typical wells,this Article proposes a detailed evaluation idea and method using a single well as an evaluation unit,combining dynamic method and volumetric method.Practical application shows that this method successfully solves the problem of huge differences in the reservoir physical properties and production characteristics of coalbed methane fields in the middle development period,ensuring the rationality of the evaluation results.
