Abstract This paper introduces the structure and principle of the volumetric borehole strain meter. We analyze and calculate the thermal calibration of the instrument. We filter the data produced by the instrument with Perstev’s filtering to remove the low-frequency trend change, and obtain the M2 wave tide factor. We correct the instrument data by the tide factor.
Key words :
volumetric strain
borehole
calibration
tidal factor
