MRIL_Prime logging T2 spectrum inversion algorithms and software improvements

本文提出了基于奇异值分解算法的改进方法,着重对增强解谱稳定性和非负约束条件处理两个方面对算法进行了改进。基于MATLAB平台开发了一套核磁共振测井数据解谱软件,通过多口井的实际应用表明,该软件的解谱结果与DPP软件结果基本一致,证实了其解谱方法的可靠性和稳定性,取得了较好的实际应用效果。

In this paper, an improved methods based on singular value decomposition algorithm is proposed, which focusing on enhancing the stability of the solution spectrum and non-negative constraints. Based on MATLAB platform, a set of spectrum disintegration software was developed. Through the practical application of several wells indicate that the results of the software solution is consistent with the DPP software results,which confirmed the reliability and stability of the solution spectrum method , and achieved good practical application.
