估算最终可采量（EUR）属性的讨论

doi:10.3969/j.issn.1002-302x.2022.06.005

摘要/Abstract

摘要： 估算最终可采量（EUR）是国外油藏工程师和储量评估师的主要研究对象，国内对EUR的内涵缺少研究，对其代表技术可采或是经济可采存在争议。深入分析国际权威机构对EUR及相关术语定义，结合储量评估工作实际，对EUR的属性进行系统讨论。文章通过实例分析得出4点结论：EUR概念内涵较宽泛，其基本属性应归为技术可采量；在资本市场和油公司生产经营等特定的应用背景下，需结合相应分类准则，赋予EUR具体含义；EUR与我国现行的CCPR中的技术可采储量有对应关系，国内对技术可采储量高度重视，实际是强化EUR管理的生动写照；国内应加强推广应用国际上EUR的研究成果。EUR属性的讨论对国内储量评估及分类体系的完善有积极作用，运用EUR评估方法和技术，在确定非常规油气资源储量最终可采量方面具有重要作用。

Abstract: Estimated ultimate recovery (EUR) is the main research area of foreign reservoir engineers and reserve estimators. However, the connotation of EUR has not been studied adequately at home. Whether EUR represents technical recoverable or economic recoverable reserves remains disputable. This paper makes an in-depth analysis of the definitions on EUR and the related terminologies made by the international authoritative organs and discusses systematically the EUR attributes in combination with the actual reserve estimation work. The paper draws four conclusions from analysis of cases. The conception of EUR has a wide range of connotation and its basic attributes can be defined as technical recoverable reserves. Against the particular application background of capital market and production business of oil companies, it is necessary to endow EUR with concrete connotations in combination with the related norms. EUR has a corresponding relation with the technical recoverable reserves defined in China’s applicable CCPR. China has attached great importance to technical recoverable reserves. This is a vivid reflection of intensified EUR management. China should step up extension and application of international EUR research achievements at home. Discussion of the EUR attributes has an active effect on perfection of the domestic reserve estimation and classification system. Application of EUR estimation method and technology plays an important role in determination of the ultimate recovery of unconventional oil and gas resources and reserves.
