用SEC标准进行储量评估应注意的主要问题

总结了SEC标准的基本要求,即储量的技术可操作性、经济条件和时间属性。提出了在按照SEC标准进行储量评估过程中,应用递减法时应重视可变成本和固定成本比例的确定,仔细进行递减类型的选取和递减率的合理确定;应用容积法时应注意准确掌握SEC标准与中国现行储量计算标准的差异,重点审查储量计算的主要参数如含油面积和有效厚度的确定方法。另外,还归纳了SEC标准和中国现行储量规范在确定含油面积和有效厚度方法上的异同,有利于掌握SEC标准并进行准确的储量评估。

Attentions should be paid in applying SEC criteria to reserve evaluation

Primary requirements of SEC criteria,such as technical operability of reserve, economic condition, and time property were summarized. In the process of reserve evaluation by SEC criteria,when successive subtraction method being applied, the major focuses are the determination of ratio of variable cost to fixed cost, the careful selection of successive decreasing model and reasonable determination of decline rate; when volumetric method being applied, the major focuses exactly grasp the differences between SEC criteria and Chinese active reserve calculation criteria, and especially examine the methods that are used to determine main parameters of reserve calculation including oilbearing area and net pay thickness. To Chinese active reserve calculation criteria and SEC criteria,the similarities and differences of the methods in determining oil-bearing area and net pay thickness were summerized. These will help to master SEC criteria and make precise reserve evaluation.
