【摘要】：SEC储量评估结果是衡量油公司发展潜力的重要指标,为减少国内与国外新增探明储量评估差异,提高当年新增探明储量对总评估结果的贡献率,对胜利油田新增探明储量SEC评估现状以及历年SEC评估结果与国内评估结果的差异进行分析,认为SEC规则变化、储量品位降低、井控差是造成国内新增探明储量SEC评估结果呈台阶式下降的主要因素。根据SEC准则,可将储量评估分为静态参数(含油面积、有效厚度、采收率)评估和动态参数(初始产量、递减率、钻井计划)评估2类。结合历年评估实例详细说明了国内与国外对以上各参数的取值差异,提出了优化国内储量管理模式和规范资料等2项减少储量评估差异的对策,以期为今后国内储量任务的完成,实现国内与国外储量评价体系的接轨提供借鉴。
[Abstract]:The result of SEC reserves evaluation is an important index to measure the development potential of oil companies. In order to reduce the difference between domestic and foreign new proven reserves evaluation and to increase the contribution rate of new proven reserves to the total evaluation results in that year, This paper analyzes the present situation of SEC evaluation of newly proved reserves in Shengli Oilfield and the difference between the results of SEC evaluation and domestic evaluation over the years. It is concluded that the rules of SEC change and the grade of reserves decrease. Well control error is the main factor that causes the SEC evaluation result of new proven reserves to decline step by step. According to SEC criterion, reserve evaluation can be divided into two categories: static parameters (oil area, effective thickness, recovery factor) and dynamic parameters (initial production rate, decline rate, drilling plan). The difference of the above parameters between domestic and foreign countries is explained in detail, and the countermeasures of optimizing the domestic reserve management mode and standardizing the data are put forward to reduce the difference of reserve evaluation. The aim is to provide reference for the completion of domestic reserve task and the integration of domestic and foreign reserves evaluation system.
