摘　　要：对江苏油区复杂小断块油田采收率标定方法的应用效果进行了评价,认为在用经验公式法计算采收率时,要考虑注采井网的完善程度;用水驱曲线法时,要考虑油藏调整工作量的大小及液量的变化情况;用递减法时,要考虑递减时机及工作量。研究分析后,找出了各种方法的应用条件及影响计算结果的主要因素,为合理选用复杂小断块油田采收率的标定方法及取值提供了依据。In this paper, the application effect of different methods on recovery calibration in complex minor fault block oilfields of Jiangsu petroliferous province is evaluated. It is proposed that the perfect degree of the injection - production well pattern must be considered while using the empirical formula method to calculate the recovery efficiency. And if the waterflood curve method is used, the workload of adjustment and the variety of liquid quantity must be considered. Also the decline timing and workload must be considered if the decline curve method is used. Based on the research and analysis, application conditions of different methods and main reasons affecting the calculating results are found out. This provides a reasonable base for choosing the recovery calibration method and recovery calculation for complex minor fault block oilfields.
