This research is some contribution to advancing acoustic sensing, offering long-range monitoring of boreholes. High sensitive distributed acoustic sensor is required in oil and gas exploration, pipeline detection, and various practical applications. In this paper, a high sensitive quasi distributed acoustic sensor was tested in borehole. The waveforms are presented and distributed audio signal and spatial acoustic imaging are demonstrated. The field test results of the sound detection illustrate a good sensitivity within the flat frequency range up to 5 kHz up to 900 m depth. The partial results obtained further developments and applications in various fields.
