SPE-PRMS标准油气储量分类体系与我国的差异性探讨及储量管理建议

The Difference between SPE-PRMS and China’s Oil/Gas Reserves Classification and Reserve Management Suggestions

目前中国石油公司应用的储量标准主要有3套,分别为国家标准、SPE-PRMS(Petroleum Resources Management System石油资源管理系统)标准和SEC标准。为了促进我国油气资源储量分类体系完善和推进储量管理国际化,通过详细解读最新的2018年SPE-PRMS的修订版,对比分析我国和SPE-PRMS标准下的油气储量分类体系的发展阶段和分类原则,明确了4个方面的差异性,主要体现在储量评估的服务目的和服务对象不同、储量定义的差异、不确定性的认识和储-产量的转化过程等。提出了石油公司储量管理4项建议,即建立SPE-PRMS标准下油公司内部的详细储量分类标准,用于储量管理和战略规划制定;深化储量的商业性和不确定性的研究,制定SPE-PRMS标准储量评估技术细则;建立SPE-PRMS标准下的储量价值评估体系,为项目优选和投资优化提供依据;完善勘探项目考核机制,建立SPE-PRMS标准下以储量价值为导向的考核指标体系。

Currently,there are three reserve standards applied by Chinese petroleum companies,namely national standard,SPE-PRMS standard and SEC standard.In order to revise China’s oil and gas reserves classification standard and promote the internationalization of reserves management,the development stage and reserve classification principles of oil and gas reserves classification system between China and SPE-PRMS standard are compared and analyzed through detailed interpretation of SPE-PRMS(revised version 2018).The differences between the two standards are clarified,which are mainly reflected in four aspects:service purpose and object of reserve evaluation,definition and standard of petroleum resources system,uncertainty recognition and conversion of reserve to production.Therefore,the paper presents some suggestions on reserves management in petroleum companies.Chinese oil companies should establish detail reserves classification for reserves management and strategic planning,further study on the commerciality and uncertainty of reserves and formulate SPE-PRMS standard reserves evaluation technical rules,set up reserves value evaluation system to provide a basis for selection and investment optimization,and also perfect the appraisal mechanism and reserve value-oriented assessment index system for exploration projects under the SPE-PRMS standard.
