摘要
本文利用J.J.Arps 的产量递减方程,推导出累积产量与递减时间的非线性拟合模型,为产量递减分析提供了一种新的方法。该方法可以判断油气藏递减类型,预测开发动态指标以及计算某个经济极限下的可采储量。实践表明:对于相同的产量递减数据,该方法具有更高的历史拟合精度和预测精度,在实际产量数据较离散时更显出它的优点。
This paper gives a new model describing the mathematical relationship between cumulation production and time by means of Arps'production decline equations,Thus a new method for production decline prediction,this methed can be used to determine the type of decline,to predict indices of reservoir performance and to determine the recoverable reserve under certain economic limit.Practices show that this method has a high accuracy in historical matclr as well as in decline predection with a same set of production data,and is more favorable in case of a set departured production data.This is-an effective production declining method.
