초록 ▼

A mud pulse telemetry system is presented for transmitting information from the bottom of a well hole to the surface. The mud pulse telemeter is a pilot operated valve which restricts the flow of mud in the drill string to set up pressure waves in the mud stream which can be detected at the surface. The pilot operated mud pulse telemeter uses a small input signal to operate the telemeter valve by pressure differentials created in the mud stream itself.

대표청구항 ▼

Telemetry apparatus for transmitting data to the surface during the drilling of a borehole by generating pressure pulses in a drilling fluid in a drill string, the apparatus comprising pilot operated valve means which includes: primary valve means adapted for mounting in a drill string segment in which the drilling fluid flows, said primary valve means being movable between a first position corresponding to maximum flow of the drilling fluid and a second position restricting the flow of the drilling fluid; an interior chamber in said primary valve; said primary valve defining a piston, one side of said piston forming one wall of said interior chamber; valve seat means for said primary valve means, said valve seat means and a face of said primary valve means cooperating to define a first variable flow orifice therebetween for flow of the drilling fluid from a drill string part upstream thereof to a drill string part downstream thereof; delivery passage means from said first flow orifice for delivering drilling fluid downstream of the pilot operated valve means; restriction means in said delivery passage means to establish a pressure drop in drilling fluid flowing past said restriction means; probe means extending from said primary valve means in the direction to project into the part of the drill string upstream of said first variable flow orifice; passage means in said probe means, said passage means being connected to said interior chamber and having inlet means for connecting to the upstream part of the drill string, whereby said interior chamber is in flow communication with the upstream part of the drill string; discharge passage means from said interior chamber for connecting said interior chamber to said delivery passage means downstream of said restriction means, the flow area of said discharge passage means being greater than the flow area of said passage means in the probe means; and second variable flow orifice means for varying the flow from said interior chamber to said delivery passage means downstream of said restriction means, said second variable flow orifice having pilot valve means variable between a first position corresponding to said first position of said position of said primary valve means and a second position corresponding to said second position on said primary valve means.
