重新认识中国油气储量标准与国际通行标准的对应关系

Reinterpretation of Corresponding Relationship between Chinese and International Standards for Oil and Gas Reserves

美国油气储量评估师按照油气藏工程分析的基本做法,不能被视为SEC规则。SEC的"尺"没有变,但评估师的"度"却可能有不同的把握。实践中,专业的知识背景、有效的地区经验、客观的评估心态,再加上合理的规则运用,四方面结合才是油气储量评估"制胜的法宝"。经对比分析认为,中国的探明已开发剩余经济可采储量和探明未开发经济可采储量分别可对应于SPE/WPC/AAPG的证实已开发储量和证实未开发储量。然而,在建立储量的思维方式、立足点、阶段性、地质储量与可采储量的对应性、不同级别储量的依存性、经济内涵及其对储量的界定作用、管理的重心等方面还存在着比较明显的差异。

The basic method that American estimators use to evaluate oil and gas reserves based on reservoir engineering analysis can not be taken as SEC rule.SEC standard is objective,however,how estimators evaluate is objective.Only based on combining the background of professional knowledge, effective local experience,objective evaluation attitude,and reasonable application of evaluation rules,can we be successful to evaluate oil and gas reserves.Comparative analysis shows that the measured remaining commercial recoverable reserves that developed and measure remaining commercial recoverable reserves undeveloped in China are respectively corresponding to SPE/WPC/AAPG proved reserves developed and proved reserves undeveloped. However,there still exist remarkable differences in the thinking mode,standpoint,and phases in the establishment of reserves,the correspondence between geological reserves and recoverable reserves,the dependence of reserves of various grades,the economic connotation and its definition of reserves,and the center of management.
