测算稠油经济采收率的LB经验法

LB empirical method of estimating economic recovery of heavy oil

在分析影响油田经济采收率的流动系数、储量丰度、操作成本、单井投资、原油价格5大因素基础上,从技术角度和经济角度综合剖析,应用功能重要度评价法,以"参数易于采集、影响程度大、相关性高"为原则,研究提出一种测算稠油经济采收率的LB经验法。通过辽河油田16个稠油油藏的实例分析,平均相对误差为0.35%,证实该方法的实用性。

This paper analyzes the five main factors affecting oilfield economic recovery both technically and economically,which are flow coefficient,reserves abundance,operation cost,single well investment and crude oil price.On this basis,LB empirical method has been developed for estimating the economic recovery of heavy oil by applying functional importance method and following the principles of 'parameters easy to acquire,big impact,and high correlation'.Cases analysis of 16 heavy oil reservoirs in Liaohe oilfield indicates an average relative error of 0.35%,thus verified the practicability of this method.
