声波测井数据采集系统的改进

The improvement of acoustic signal transmission system

声波数控采集技术实验教学是地球物理测井专业必修的实验课程,通过实验可以掌握采集系统的基本结构及测井数据采集原理。但由于用于教学的声波数据采集系统设备采用的是90年代的技术,所配套的软件系统采用Quick Basic,显然已经不能满足现代教学的要求。针对整套设备软件和硬件中存在的问题,采用Visual C++6.0对原数据采集系统进行了改写,改进了图形输出功能和操作界面,并对电路进行了改进。使得信号采集的过程更易于学生理解和操作,收到良好的教学效果。

Acoustic signal transmission and data acquisition system is a most important component to sonic logging technology,which can be applied into operation controlling,quality monitoring and large enhanced the well logging efficiency.The acquisition software was developed by QuickBasic language and the run environment was DOS,so this software is not available for the modern teaching.Just for this reason,we rewrite the software using Visual C＋＋ and,modify some component of data acquisition circuit and control panel.By doing these.The new program has better operation interface and the new system has higher signal resolution and more efficiency in data acquisition.
