由于国民经济发展对油气资源的需求量日益增加,对边际储量的评估就显得尤为重要。针对边际储量的特点及应用常规标准进行评估所遇到的问题,探讨了评价准则,提出了集"评价基础、评价单元、评价参数、评价方法"四位一体的评价思路。并在工业油流标准的基础上,提出了产能达标度的新概念,解决了边际储量评估中长期困扰的井间及单井产能可比性问题,而且实现了由定性到定量评价的转化。

With the development of national economy and increase in demend for petroleum resources, the evaluaion of marginal reserves has become more and more important. Based on the study of the characteristics of marginal reservesand problems encountered in evaluation by conventional criteria, new evaluation criteria are discussed. A new evaluationidea including the basis, the unit, the paramter and methods of evaluation are proposed. According to commercial oilflow standard, a new concept of productivity ratio(DBD) is also proposed. This thus solves the problems of comparabitity of produtivity between wells and of single well that puzzled people for a long time in the marginal reserves evaluation, and could realize the transformation from qualitative to quanitative evaluations.
