Design Of The Analysis Platform Of The Induced Polarization Tool

Induced polarization logging as a specific method of Electrochemical Logging is an important means of obtaining physical parameters such as polarizability. In the logging operation, how to control downhole logging tool through the ground work platform, while receiving the data collected by logging tool real time, analyze the data and display, which is of great practical significance in Logging artThis thesis describes the status of the current domestic oil well logging geology, combining the advantages of induced polarization logging proposed logging tool significance of induced polarization analysis platform. Discussion on design method based on LabVIEW environment PC platform analysis and implementation process. Through analysis of the actual needs of the project, given the overall platform architecture based on modular thinking, and then were on the CAN communication module, data analysis and processing, document management and other modules of analysis and design. This article will call Lab VIEW multithreading technology, dynamic link libraries, and MATLAB script flexibly together to achieve the process of logging in the logging instrument control commands to send, receive, polarization data strata attenuation spectrum inversion relaxation time spectrum, and so save and playback display of graphics and data files. To meet the logging data process real-time, data processing capabilities, and user-friendly software program, simple operation, while this platform has a scalable, easy to modify and add modular functionality of the program, easy to post function improve.Finally, after verification, the analysis platform capable of accurately and reliably through the CAN bus to communicate with the tool, can meet the needs of real-time logging, but also has a save and view data, post-processing data analysis functions, to the platform design purpose.
