变流量非稳定井流问题的线性系统模型

Linear system model of variable discharge non-steady well-flow problem

本文用线性系统方法研究了变流量非稳定流抽水试验资料。在理论上对其井流问题的非稳定流线性系统模型进行了数学分析。这种用系统辨识的方法不同于传统的解析法,也不同于数值法,是抽水试验分析法的一种验证和补充。

In this paper, a study on the variable discharge unsteady flow pumping test data is made using a linear system method. A mathematical analysis is made theoretically on this model for the well flow problem. This method of systematic identification is different from either the traditional analytical method or the numerical method. It is an examination and supplementation to the pumping test anglysis.
