Mud channel characterization over depth

摘要

A system for optimizing a mud-pulse telemetry system, the system including: a plurality of sensors distributed along a drill string adapted for being disposed in a borehole, each sensor configured to perform a measurement of a characteristic of at least one of mud in a column within the borehole and a mud-pulse telemetry signal propagating in the mud; and a processing unit for receiving the measurements, the processing unit comprising an algorithm to compile a data set from the measurements and to determine a parameter of the mud-pulse telemetry system using the data set to optimize the mud-pulse telemetry system. A method and a computer program product are also provided.

1. A system for optimizing a mud-pulse telemetry system, the system comprising:
a plurality of sensors distributed along a drill string adapted for being disposed in a borehole for obtaining measurements of a characteristic of mud along a mud column in the borehole from substantially a surface location to substantially a downhole pulse generator, wherein the measurements of the characteristic of the mud includes a measurement of noise in the mud column; and a processing unit configured to receive the measurements from the plurality of sensors, model the noise in the mud column to a white Gaussian noise, and subtract the noise from a mud pulse telemetry signal in the mud column.
