为有效区别和准确使用美国PRMS和SEC两种储量评估准则，通过对两种储量分类体系的分析对比，明确了两种准则的相同点和不同点，得到两种准则都要求具有“已发现、可开采、商业性和经济剩余量”的4个要素，SEC在PRMS的基础上不仅评估证实储量，也选择性披露概算储量和可能储量。通过8个方面的分析对比，二者在流体界面确定、断层上下盘储量级别定义、PUD的外推范围、类比油藏、可靠技术、5年PUD规划、经济性、油价及成本等8个方面的界定与要求存在差异与不同。在价值评估方面，SEC按目前的经济条件进行经济评估，强调储量的经济生产能力和公司的最低收益； PRMS则以预测经济条件为基础进行经济评估，强调储量的商业价值，侧重于公司的投资回报。

To effectively distinguish and accurately use America PRMS and SEC reserves evaluation rules, we compared and analyzed the two reserve classification systems. The two reserve rules have similarities and differences. The reserves must be found, recoverable, economical and with economic surplus to be confirmed by both PRMS and SEC. The SEC not only evaluates proved reserve as dose PRMS but also evaluates possible and probable reserve. The differences between the PRMS and the SEC include liquid contact, fault upthrow and down throw reserve definition, PUD offset, analogy reservoir, reliable technique, 5 year PUD plan,economic, oil price & cost. The SEC reserve evaluation is based on the present economic circumstance, because it emphasizes oil and gas economical production and the lowest income of the company. The PRMS reserve evaluation is bases on forecasting economic circumstance, as it concerns the commercial value of the reserve and the return of the company's investment.
