非常规油气资源是指在成藏机理、赋存状态、分布规律以及勘探开发方式等方面有别于常规油气藏的油气资源。现在非常规油气资源的开发利用日益受到重视,且已成为常规油气资源的战略性补充。目前,国内对于非常规油气资源的评价,还未形成一个较为明确和有针对性的评价体系。基于非常规油气聚集的成藏机制和分布特征,本文详细介绍了国内外5种非常规油气资源的评价方法：美国地质勘探局的主流方法——类比法和新推出的随机模拟法,以单井储量估算法为代表的典型统计法,以油气资源空间分布预测法为代表的特殊统计法,以连续型致密砂岩气藏预测法为代表的特殊成因法。上述方法为我国非常规油气资源评价及新一轮的全国油气资源评价提供了理论基础。

The unconventional hydrocarbon resources are different from the conventional hydrocarbon resources in the aspects ofaccumulation mechanism,occurrence,distribution,exploration and development method,etc.As the strategic supplements of conventional resources,the unconventional hydrocarbon resources are becoming highly valued.But now,an effective evaluation system is not yet built up for the evaluation of unconventional hydrocarbon resources in our country.Based on the accumulation mechanism and distribution characteristics of the unconventional hydrocarbon resources,five evaluation methods for unconventional hydrocarbon resources are introduced,including：analogy method,the major method of USGS;stochastic simulation method,the new developed method of USGS;reserve estimation method for single well,the typical statistical method;prediction method of hydrocarbon spatial distribution,the special statistical method;prediction method of continuous tight sandstone gas reservoirs,the special genetic method.These evaluation methods provide theoretical basis for the evaluation of the unconventional hydrocarbon resources and the newnational hydrocarbon resource.
