Downhole telemetry systems with voice coil actuator

摘要

Pulse telemetry systems and methods for communicating digital data from a wellbore to a surface unit are presented that include a valve fluidly coupled to drilling fluid. The valve adjusts pressure in a drillpipe to cause pressure transitions within the drilling fluid within the drillpipe to transmit data over the drilling fluid. The valve includes a voice coil actuator for developing the pressure transitions within the drilling fluid. Other systems and methods and are included.
