变产量测试资料的分析

Analysis of Changing Production Rate Testing Data

变产量引起地层压力波的重叠传播，对变产量进行叠加，能真实地反映地层压力由于产量变化所发生的动态效应。随着变产量计量数据的日趋准确，应用变产量叠加方法，输入变产量的真实值可使典型曲线的压力历史得到很好的拟合，取得可信的分析结果。文中给出了变产量叠加方法应用的示例，并与霍纳方法及典型曲线拟合方法进行了对比分析。

Changing production rate caused formation pressure wave propagation superposition. It can make the dynamic effect of the changing formation pressure clearly to superposite the production rate. With the value of changing production rate becoming accurate, using superposition method, the history matching will be better and the analyzing results will be more reliable. Examples of superposition analysis method for changing production rate test are given in the paper. The results are compared with the results getting from Horner method and type curve matching method.
