Design of data acquisition control software of far detection azimuthal acoustic logging tool

The acoustic logging technology of azimuthal far detection has developed rapidly in recent years. The data acquisition and control software is an important functional module of the logging tool system. Its main function is to complete the real-time command control and data transmission between the surface acquisition and control platform and the downhole tools. The data acquisition and control software module of the far detection azimuthal acoustic logging tool is connected to the imaging logging system in the form of a tool library. The software is mainly composed of tool initialization, data acquisition, data analysis and processing, tool parameter setting, command issuing encapsulation, file operation, real-time waveform drawing display, real-time waveform processing, data playback, help system, etc. Multi-thread programming technology is adopted in the program design to improve the timeliness of interaction with the logging master control platform and the response speed of the program. Laboratory and field tests show that the overall and each functional module of the data acquisition and control software of the far detection azimuthal acoustic logging tool operates stably, and can meet the requirements of the tool control, data reading, data analysis and processing, file recording and data interface with the field logging acquisition and control platform in the field application process. The data acquisition and control software module provides the basis for further function optimization and field application of the tool.
