摘要
提出了用来处理含有噪音的测试压力数据的光顺样条滤波算法。数据处理后可以得到连续、光滑的压力导数 ,然后用典型曲线拟合方法进行试井分析。该方法简单易用 ,计算精度高。实例证明该方法是有效的 。
An algorithm called smooth spline filter is presented to pre-processing a set of measured pressure data. It can be obtained smooth, continuous pressure derivative functions from processed well-test data. It can be used for type curve matching. This method reduces computing complexity and promotes identification efficiency. From experience with thousands of well tests, we have chosen several examples to illustrate the need for pre-processing the data. The examples show that smooth spline filter method is effective and practical.
