SYSTEM FOR SPATIALLY MONITORING A BOREHOLE IN REAL-TIME

摘要

There is provided a monitoring system (300) for monitoring within a borehole (10). The system (300) comprises a probe assembly (100) operable to be moved within the borehole (10) for sensing one or more physical parameters therein, a data processing arrangement (110) located outside the borehole (10), and a data communication link (120) operable to convey sensor data indicative of the one or more physical parameters from the probe assembly (100) to the data processing arrangement (110) for subsequent processing and display and/or recording in data memory (140). The probe assembly (100) includes one or more sensors (320) for spatially monitoring within the borehole (10) and generating corresponding sensor signals (360). Moreover, the probe assembly (100) includes a digital signal processor (310) for executing preliminary processing of the sensor signals (360) to generate corresponding intermediately processed signals (370) for communication via the data communication link (120) to the data processing arrangement (110). Furthermore, the data processing arrangement (110) is operable to receive the intermediately processed signals (370) and to perform further processing on the intermediately processed signals (370) to generate output data for presentation (130) and/or for recording in a data memory arrangement (140). The system (300) is of benefit in that it enables real-time spatial monitoring of the borehole (10) to be achieved.
