Abstract

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
