多层次模糊综合判别法在煤层气资源丰度潜力评价中的应用

我国煤层气勘探开发尚处初级阶段,煤层气资源丰度潜力评价体系尚不健全.研究应用多层次模糊数学方法,通过对煤层气成藏条件分析探讨,建立多层次模糊判别模式,并根据国内外煤层气勘探开发经验,给出评价函数及函数拐点值.并将方法应用到选取的靶区盆地,定量计算煤层气资源丰度潜力,估算资源量,为靶区提供煤层气勘探决策依据.

Multilevel Fuzzy Comprehensive Assessment Method and Its Application in the Abundance of CBM Resources Potential

CBM exploration and development is still at primary stage in our country,the CBM resources potential abundance evaluation system is not sound.The study in the application of multilevel fuzzy mathematic method,through the analysis and discussion on coal-bed gas reservoir forming conditions,establishment of a multi-level fuzzy judgement model,and according to the experience of the coalbed methane exploration and development at home and abroad,gives the evaluation function and function point value.And the methods applied to selected targets basins,the quantitative calculation of coalbed methane resources abundance of potential and estimate resources,provides the coalbed methane exploration decision-making basis for the target.
