Mud pulse telemetry |
摘要 |
A method and related system for detecting mud pulse telemetry by measuring pressure fluctuations in drilling fluid by measuring mud pressure pulses at two locations. A first location is somewhat downstream of the mud pump and desurger and a second location is proximate to the mud pump and desurger. Given these two pressure signals they are subtracted to create a difference signal where the presence or absence of mud pressure pulses is determined by pressure spikes caused by the interaction of mud pressure pulses. A second method measures the mud pressure pulse at only one location.
