HRAS高分辨率声波测井仪典型故障分析与排除

Malfunction Analysis and Maintenance for the High Resolution Acoustic Logging Tool(HRAS)

声波通过岩石,其波的速度、幅度有时甚至频率都会发生变化,目前常用的是声波速度和幅度在不同介质中会有不同变化这两个特性。HRAS高分辨率声波,主要利用这二特性对地层进行测量。HRAS高分辨率声波测井仪的正常工作与地面系统、REC仪器、D4C井径等都有着密切关系,只有对仪器的原理框图和信号流程有非常全面的理解,才能在对故障进行系统的、全面的分析基础上,快速制定解决问题的方案。

When acoustic wave passes through rocks, its velocity , range and even frequency will change. The （HRAS） high resolution acoustic logging tool measures the stratum by using the vibrational features of acoustic velocity and range in different media. Surface system, REC circuits and D4C caliper are closed associated with the performance of HRAS. Comprehensive understanding of the system principle block diagram and signal process of the instrument will be helpful for a systematic and rounded malfunction analysis, and responding quickly with a ~ast solution.
