Designing And Implementing Of MRIL-P NMR Logging Data Process&Interpretation Software

At present,the MRIL-P nuclear magnetic resonance logging tool is more and more used in the domestic application,the effect is also relatively good nuclear magnetic resonance logging tool,the main use of Petrosite software for data processing and interpretation.The price of the software is more expensive,and due to the lack of software source code,it is difficult to carry out targeted two development.Developed a with independent intellectual property rights of the nuclear magnetic resonance logging data processing and interpretation software,on the one hand can be as foreign nuclear magnetic resonance logging data processing and interpretation method and system for part of alternatives to reduce costs;on the other hand,in production and scientific research can be carried out for the secondary development,is conducive to the promotion and improvement of nuclear magnetic resonance logging data processing and interpretation techniques,of oilfield exploration and development to the positive role.From the MRIL-P NMR logging data processing perspective of development data format solution encoding and observation mode analysis and automatic identification,the original measurement data pre processing,T2 spectrum inversion and interval pore separation,calculation of reservoir parameters,magnetic product development and chain at the physical process and software module.In the time domain m.cls data decoding,through the analysis of the characteristics of data,the successful extraction of original data information,and the introduction of software comparison is consistent;in the pre-processing of the original data,through the analysis of 80 kinds of observation modes,the mode of automatic identification,to determine the 5 steps of echo data extraction;the truncated singular value decomposition method of T2 spectrum inversion method is developed based on using three spline interpolation to achieve the T2 spectrum smoothing and splicing,total porosity and effective porosity curves obtained were consistent with the introduction of basic software,the average absolute error is less than 0.3%;according to a variety of methods to complete the permeability parameter calculation,and routine curve combined with dual water model for water saturation calculation,the results are two curves with the introduction of software processing results in the development of software,communication;A chain processing technology and processes,drawing technology,greatly increases the efficiency of the whole software processing,than that of imported software to improve more than 3 times.Through the selection of NMR logging some wells of the verification and evaluation of software processing results,this software can meet the actual needs of the NMR logging.At last,the development of log processing software are analyzed and discussed.
