Abstract: In this paper,Fast Fourier Transform and arrays are introduced into calculations of down-hole dynagrams(DHD)based on Gibbs algorithm so that a fast and efficient way to calculate DHD may be set up and the possibility of real-time data calculation for DHD is provided.This method could be appropriately used in field data acquisition system and computer system for batch processing of dynagrams.

摘要： 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。
