摘要：

摘要：通过分析目前人们对资源量含义的不同理解和认识，探讨了资源量的不同含义的差别。总结了两种不同资源评价思路，一是以生烃单元为出发点的成烃思路，它是根据油气生成、运移、聚集的基本原理，建立油气生、运、聚地质模型和数学模型，计算油气生成量，从而再计算出资源量；二是以聚集单元为出发点的成藏思路，它是在油气地质综合分析基础上，以聚集单元为目标划分出评价单元，评价出油气藏或油气储存单元规模和数量分布，然后计算出资源量。讨论了影响资源评价的主要因素。提出了加强我国油气资源评价工作的建议： 1) 加强资源评价方法研究，完善我国油气资源评价技术方法体系。2）完善我国油气资源分类体系及分类标准，推进我国资源分类与国际接轨。3）建立我国动态资源评价机制，建立国家层面的资源评价队伍、评价系统和数据库。

Abstract:

Abstract: By analyzing different understandings of petroleum resources，we discuss the differences in connotations of the various concepts of petroleum resources and put forward two different resource assessment approaches.One is hydrocarbongenerationbased approach which takes hydrocarbon generation units as basic appraisal units.Based on principles of hydrocarbon generation，migration and accumulation，it establishes geological models and mathematical models to calculate hydrocarbon generation amount and eventually total resources.The other is hydrocarbonaccumulationbased approach which takes hydrocarbon accumulation units as basic appraisal units.On the basis of comprehensive analysis of petroleum geology，it figures out the number and size distribution of oil/gas accumulations or cells and then calculates undiscovered resources.We also discuss main factors that influence resource assessment.At last，suggestions are made to improve petroleum resource assessment in China：1）to strengthen research on resource assessment methods and complete petroleum resource assessment system；2）to complete classification criteria and system for oil/gas resource in order to bring them in line with international standards；3）to set up a dynamic resource assessment mechanism and to establish the national team，system and database for petroleum assessment.
