摘要:

基于中国页岩气形成、成藏与富集地质条件研究、勘探开发进展与发展前景分析,通过中国与北美页岩气地质特征、勘探开发阶段对比,充分剖析北美页岩气资源评价方法与技术,基本明确了中国页岩气资源评价的原则与评价流程,初步建立了中国页岩气资源评价方法体系,包括体积法、类比法、容积法、含气量法和单井EUR法5种资源量估算方法和特尔菲法一种资源评价结果汇总法,形成了有效厚度、含气量、含气饱和度、孔隙度等关键参数体系、参数取值方法和参数取值标准,估算了中国3类页岩气资源量,指出了有利页岩气勘探领域。

Abstract:

Based on the research of the geological conditions of the shale gas formation,accumulation and enrichment in China,the analysis of exploration and development progress and development prospect,and the comparison between the Chinese and north American shale gas on geological characteristics,the exploration and development stages,the paper has dissected fully the north American shale gas resources evaluation methods and technologies,and has demonstrated the basic Chinese shale gas resource evaluation principles and evaluation procedure,preliminary established five resource estimation methods of China’s shale gas resources evaluation system,including volume method,analogy method,volumetric method,gas content method and single well EUR method and one resource evaluation results summary method such as Delphi method.It formed effective parameters such as thickness,gas content,gas saturation and porosity, selection of key parameters,and method of obtaining parameter value and parameter standard.It calculated the three types of shale gas resources in China,and pointed out the favorable shale gas exploration areas.

Key words: Shale gas, Geological characteristics, Resource evaluation, Method and technology, Parameter standard, Marine, Transitional, Continental, China
