摘　　要：二维核磁共振测井观测模式是以获取特定地层信息为目标的数据采集方式,它直接决定着核磁共振谱仪对不同类型储层的适应性以及获取原始数据的可信度.本文从观测模式的组成元素以及工作机理出发,采用C#语言开发了一套具有可视化功能的二维核磁共振测井观测模式设计软件.该软件支持二维核磁共振测井以及核磁共振岩心分析仪的观测模式设计,同时提供了三种采集参数编辑方式、观测模式优化机制以及图形化显示等功能,实现了观测模式的灵活调整,解决了当前主流二维核磁共振测井观测模式中存在的采集参数固定、不宜灵活调整从而导致所采集的原始数据信噪比低下、储层中流体弛豫特性加载不完全等问题.此外,软件还提供了观测模式的采集参数信息以及采集时序信息的输出功能等.Two-dimensional(2D)NMR logging activation sets are acquisition means aiming at obtaining specific formation information,affecting the adaptability of NMR instruments to different types of reservoirs and the reliability of the original data.In this work,a software with the visualization function for designing 2D NMR logging activation sets was developed using the C#language,based on the component elements and working mechanism of activation.The software supported the design of activation sets for 2D NMR logging and NMR core analyzer.Meanwhile,the software provided three kinds of parameter editing methods,observation mode optimization and graphical display functions,and thus realized flexible adjustment of the activation sets.It solved the problems in the former mainstream 2D NMR logging activation sets,such as low signal-to-noise ratio of the raw data,incomplete loading of fluid relaxation characteristics due to inadequately fixed acquisition parameters and inflexible adjustment etc.In addition,the software also provided outputs for acquisition parameters and acquisition timing.
