ATOMIC CLOCK FOR DOWNHOLE APPLICATIONS

摘要

A system and method for acquiring seismic data are disclosed. The system comprises a controller (18) for causing the generation of a seismic signal, where the controller has a first clock used for time-stamping a record of th e generated seismic signal. A seismic receiver (158) is deployed in a wellbore so as to detect the generated seismic signal. An atomic clock (205) is disposed in or with the seismic receiver for time-stamping a record of the detected seismic signal. The atomic clock is synchronized with the first clo ck prior to being placed downhole.
