本文利用矩阵和快速付里叶变换进一步深化井下功图的吉布斯(Gibbs)解,从而形成了一种快速有效的井下功图计算方法,并提供了实时计算井下功图的可能性。本方法不仅适用于高采样率的野外数据采集处理系统,也适用于批量处理示功图的计算机系统。
In this paper, we use the matrix and fast Fourier transform to further deepen the Gibbs solution of downhole work diagrams, thus forming a fast and effective calculation method of downhole work diagrams and providing the possibility of calculating downhole work diagrams in real time. The method is not only suitable for field data acquisition and processing system with high sampling rate, but also suitable for computer system for batch processing of dynamometer.
