摘要
采用Arps递减分析和模型预测2种方法对塔河油田缝洞单元的可采储量进行计算。由于模型预测不存在递减段选取的问题,因此可以把模型预测计算出的结果作为参考,与Arps递减分析计算出的结果进行比较,然后再调整递减段,从而得到比较可靠的结果。因此建议2种方法结合起来对塔河油田缝洞单元的可采储量进行计算。同时对塔河油田动态储量的递减分析还提出了关于其递减段选取的标准。
Arps decline analysis and model prediction were used to calculate recoverable reserves of fracture - cave unit in Tahe oilfield. Due to no need for choosing decline fraction in model prediction, the result of this method can be compared with the result of Arps decline curve analysis, then regulating the decline fraction in Arps, it is accurate to calculate recoverable reserves. So the two methods should be combined with for calculating recoverable reserves of fracture - cave unit.
