METHOD AND APPARATUS FOR TELEMETRY

摘要

A mechanism to speed the effective transmission rate of information in a mud pulse telemetry system. Embodiments of the invention may transmit data gathered by downhole tools to surface devices by inducing pressure pulses into the drilling fluid. The mud pulse communication system gathers data from the devices and transmits the data to the surface by creating mud pulses in the drilling fluid within the drill string. In particular, the methods and related apparatus may send a first datum of a first parameter in an uncompressed form, and send a second datum of the first parameter in compressed form.
