长春油田双阳组经济可采储量评价

Evaluation on economic recoverable reserves of Shuangyang formation in Changchun oilfield

选用经济极限含水率法和现金流通法对长春油田双阳组经济可采储量进行评价。对于前者,在前人研究的基础上结合已有经济参数及水驱曲线推导出经济极限含水率公式;对于后者,除重点预测产量及注水量外,还充分考虑操作成本、相关税费、不同原油价格等经济参数影响。两种方法的结合能有效地计算出长春油田双阳组经济可采储量,正确指导后期开发。

Two methods are selected to evaluate economic re- coverable reserves of Shuangyang formation in Changchun oilfield:Economic Limit Water-cut Method and Cash- flow Method.Based on previous foundation,with the combination of available economic parameters and water- flooding curve,the former method can be developed; while for the second method,besides forecasting the pro- duction and waterflood injection,it also takes running cost,related tax expense,different crude oil prices and other economic parameters into consideration.Therefore, by using these two methods together,the economic recov- erable reserves of Shuangyang formation can he effectively worked out,which provides good guidance for later stage development.
