基于中国特殊地质特性的页岩气储量评价方法研究

页岩气成藏模式及赋存特点都不同于常规天然气，目前国内已发展比较成熟的常规天然气资源储量预测方法并不能直接适用于页岩气资源储量的预测。文章根据页岩气发育条件及富集机理，结合油气资源评价方法的基本原则，系统归纳了国内外常用页岩气资源潜力定量计算方法，结合中国地质背景的复杂性和页岩气勘探开发程度较低的现状，建议在页岩气开发不同阶段采用不同的储量评价方法。根据国内天然气储量评价经验，文章建议将齐波夫定律引入页岩气储量评价方法体系。

Evaluation Methods Analysis About Resources and Reserves of Shale Gas Based on Chinese Special Geological Characteristic

The mature valuation methods of conventional gas reservoir cannot be adopted directly by shale gas reservoir because of its different accumulation model and occurrence characteristics. Based on its characteristic of existence, enrichment and principle of evaluation, the essay makes a systematic summing up of frequently-used methods of evaluating shale gas reservoir at home and abroad. And by realizing the complicated geology background and the current situation of low-degree development of Chinese shale gas, we make a suggestion of adopting corresponding methods at different periods of development. According to the native mature experience of evaluating reservoir of gas, we boldly table a proposal of introducing Zipfs Law into our evaluation system.
