INSTRUMENTED CEMENTING PLUG AND SYSTEM

摘要

A system for cementing a tubular member (11) in a well bore includes a cementing plug (29). The cementing plug (29) includes at least one sensor (41,43,47,49). The system transmits a value measured by the sensor to a surface location. The system may transmit the value measured by the sensor through a cable (33) connected between the plug (29) and the surface location. Alternatively, the system may transmit the value measured by the sensor acoustically to the surface location.
