中国现阶段页岩气资源评价方法分析

为寻求现阶段我国页岩气资源评价合适、准确且易行的方法,文中通过系统分析国内外页岩气资源评价方法,阐述了国内外具有代表性的页岩气资源评价方法的原理、使用范围及其关键参数获取,分析了每种方法现阶段在我国进行页岩气资源评价时,因勘探程度、资料条件、地质条件各异而存在的问题和所受的限制(如动态法、静态法中的地质类比法、成因法、体积法和综合分析法)。认为基于体积法改进的条件概率体积法是现阶段我国进行页岩气资源评价易行且有效的方法,但仍需根据不同地区和不同层系页岩气的发育背景、富集机理等特征有针对性地改造和完善。

Analysis of shale gas resources assessment method in China

In order to find a suitable,accurate and feasible method for shale gas resource assessment in China at the present stage,shale gas assessment method were systematically analyzed,and the principle,application range and key parameter acquisition of some representative shale gas resources assessment methods were described;because of the differences of shale gas exploration degree,data and geological conditions in different areas,the existing problems and limitations of shale gas assessment in China of each method were analyzed in the paper.It is concluded that the probability volume method is considered as an easy and effective method for shale gas resources assessment in China at present stage,but this method still needs pertinence transform and improvement according to development and accumulation characteristics of different shale series in different areas and formations.
