胜利油田新增探明储量SEC评估现状与分析
|
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。
The SEC reserve evaluation results are important indicators to measure the development potential of oil companies. In order to decrease the difference between domestic new- added proved reserves and SEC reserves,and increase the proportion of new-added proved reserves to the total reserves,the status and difference between domestic reserves and SEC reserves in the past years in Shengli Oilfield were analyzed. It is considered that the SEC rules change,the low quality of reserves and unfavorable offset resulted the stepped down tendency of SEC results for domestic new-added proved reserves. The parameter differences were illustrated by using evaluation examples of past years,including static parameters(oil-bearing area,net pay and recovery factor)and dynamic parameters(initial rate,decline rate and drilling plan). Two countermeasures:management mode optimization for domestic reserves and normalization of evaluation data,were put forward to reduce the differences.This research has some reference significance for the reserves task completion of domestic oil companies and the integration of SEC reserves evaluation systems.
