摘要:

本文研究了试井中压力测试数据的预处理方法。通过信号编排,Kalman滤波,B样条函数拟合,可以获得测试时间内任一点的压力和压力导数值。两个实例显示了该方法的特性。

Abstract:

A pre-proceeding method of the pressure measuring data in well testing is presented in this paper. Using the pre-proceeding method of signal arrangement, adaptive Kalman filtering and B spline function fitting, we can obtain the pressure and pressure derivative at random point in testing time. Two examples illustrate the characteristics of the method.

Key words: Well testing, Pressure measuring, Pre-processing, B spline function, Filtering
