声波信号数据采集是石油勘探中声波测井技术的重要组成部分，通过声波测井，可确定声波在地层中的传播速度，从而计算地层的孔隙度。目前教学实验采用的声波测井数据采集系统，软件界面单一，得不到实验数据，只能做定性理论分析。硬件方面也存在测试介质无法改变，数据采集速度及精度不够高等问题。因此，针对该系统存在的问题进行了改进．使其更易于学生理解测井流程及原理，取得了良好的实验教学效果。

Acoustic signal data collection is the most important part of sonic logging technology in oil exploration, through which, the sonic velocity of silder wave that propagated in the downhole formation can be determined, consequently can be used to calculate porosity of reservoir. Acoustic signal data collection teaching experiment is a required course in geophysical logging. The structure and theory of acoustic signal data system can be learned by experiments. But the teaching experimental system is based on technology of the 1990＇s andis not available for the current curriculum with such bad factors as poor system contact surface, impossibility to get data of experiment and fit experiment, single-function for qualitative analysis, single experimental material, lack of velocity and poor precision to acquire experiment data, etc. Therefore, the paper improves the teaching system and makes it easier for students to understand logging processes and principles and enhances the effects of the experiment teaching.
