摘　　要：运用模糊统计法,以木里地区的物化探资料为例,对木里地区的天然气水合物资源分布情况进行预测,结果表明,应用这种方法进行水合物预测是可行的,预测区域与已知钻遇到水合物的钻孔有很好的对应,且圈定了6个水合物有利区,这不仅对物化探方法技术优选、异常特征分析和评价指标确立等工作具有指导意义,而且对加速推进我国陆域冻土区天然气水合物资源勘查与潜力评价工作具有十分重要的意义。In this paper, the fuzzy statistic method was used to forecast the distribution of natural gas hydrate resources in Mull area, with the geochemical exploration data obtained from Mull area as the study object. The results show that it is feasible to use this method to predict hydrate. The prediction area is well correlated with the drilling of the known hydrate, and the six hydrate favorable regions were delineated. The result obtained by the authors is of great significance not only for the optimization of material and geochemical exploration methods, the analysis of abnormal characteristics and the establishment of evaluation indexes, but also for the acceleration of the exploration and potential evaluation of natural gas hydrate resources in China＇s landfill regions.
