摘要：

非常规与常规油气聚集体既有密切关联又存在本质区别。非常规油气区带具有4个基本特征，包括用邻井推测未钻井区域生产特征的非可靠性、各井估算最终可采量（EUR）的统计分布具有可重复性、连续油气系统的区域性及游离烃的动力学特征具非达西性。因此，非常规油气面临比常规油气更大的技术和商业挑战，其资源储量应在7个方面创新管理理念，包括储量资产价值化、经济可采储量为核心的分类体系、全生命周期一体化模式、缝控体积和井控储量、储层与生产特征的非均质性、风险定量评价和经济可采储量保守评估等。深化非常规油气区带特征研究与创新资源储量管理，有利于推进中国非常规油气的勘探开发及油气资源管理体系的完善。

Abstract: Unconventional oil and gas reservoirs are closely related but fundamentally different from conventional oil and gas reservoirs. There are four basic characteristics of unconventional oil and gas play, i.e., unreliability of predicting production performance by offset wells in area without well drilling, repeatability of the statistical distribution of the estimated ultimate recoveries (EURs) from wells, regionality of continuous petroleum system, and non-Darcy dynamics of free hydrocarbons. Therefore, the development of unconventional oil and gas faces greater technical and commercial challenges than that of conventional oil and gas, and the concept of resource and reserve management should be innovated in seven aspects, i.e., value management of reserve assets, classification system with economically recoverable reserves as the core, integrated model in the whole life cycle, fracture-controlled volume and well-controlled reserves, heterogeneity of reservoir physical property and production performance, quantitative risk evaluation, and conservative estimation of economically recoverable reserves. An in-depth study on the characteristics of unconventional oil and gas plays and innovative management of resource and reserve will support to promote the exploration and development of unconventional oil and gas resource and improve resource management system in China.
