摘要
基于LEAD平台研发了与MRT核磁共振测井仪器配套的测井数据处理解释软件,从MRT数据采集、数据处理、储层参数计算3个方面详细阐述了MRT数据预处理、T2谱反演、T2谱分析、时域分析、孔隙度渗透率饱和度参数计算的原理和方法。现场应用表明,该软件处理速度快、精度高,处理效果符合地层规律,经过和Petrosite软件测试对比,处理效果达到国外同类软件水平。
Since the popularization and application in 2014,MRT,the domestic self-developed multi frequency NMR logging tool has been used in more than 100 wells in many oilfields.In order to meet the urgent needs of the oilfield,this paper develops a MRT logging data processing and interpretation system,which is integrated in the LEAD logging interpretation platform.From three aspects as follows MRT data acquisition,data processing and reservoir parameters calculation,this paper discusses in detail the basic principles and processing methods of MRT data preprocessing,T2 spectrum inversion,T2 spectrum analysis,time domain analysis,as well as the calculation of porosity,permeability and saturation.Oilfield application shows that the software has high processing speed and high accuracy,and the results are in accordance with the law of strata.After being compared with the Petrosite results,the software can reach the level of similar foreign software.
