Abstract
A downhole valve is described. The downhole valve has a pilot valve section and a tool section. The pilot valve section has a first tube. The tool section has a second tube slidably coupled to the first tube of the pilot valve section so as to provide fluid communication between the pilot valve section and the tool section. The tool section can be in the form of a signal valve section of a mud pulse telemetry valve, a reamer, a vertical steerable tool, a rotary steerable tool, a by-pass valve, a packer, a whipstock, or stabilizer.
Claims9
An assembly, comprising:
- a first tubular member having a first bore and a first end;
- a second tubular member having a second bore and a second end, the first end of the first tubular member connected to the second end of the second tubular member to form a tool joint;
- and
- a downhole valve disposed within the first bore and the second bore so as to span the tool joint, the downhole valve having a pilot valve section secured to the first tubular member and a tool section secured to the second tubular member, the pilot valve section and the tool section fluidly communicating through a slip joint formed when the first tubular member is coupled to the second tubular member, the slip joint configured to form a fluid tight connection allowing for rotational and longitudinal movement between the pilot valve section and the tool section, the pilot valve section including a pilot valve having a pilot valve member configured to be connected to an actuator to selectively move the pilot valve member into a closed or open position;
- wherein the downhole valve is a mud pulse telemetry valve, and the tool section is a signal valve section of the mud pulse telemetry valve.

A downhole valve, comprising:
- a pilot valve section having a first tube in fluid communication with a pilot valve, the pilot valve provided with a pilot valve member configured to be connected to an actuator to selectively move the pilot valve member into a closed or open position for providing a differential pressure or fluid flow through the first tube;
- a tool section having a tool and a second tube, the second tube slidably coupled to the first tube of the pilot valve section to form a slip joint separate from the tool so as to provide fluid communication between the pilot valve section and the tool section, the tool operable by differential pressure or fluid flow ported through the first and second tubes;
- wherein the pilot valve section is secured within a first bore of a first tubular member and the tool section is secured within a second bore of a second tubular member, wherein the slip joint is formed by coupling the first tubular member to the second tubular member, the slip joint being disposed within one of the first tubular member and the second tubular member and configured to form a fluid tight connection allowing for rotational and longitudinal movement between the pilot valve section and the tool section;
- wherein the downhole valve is a mud pulse telemetry valve, and the tool section is a signal valve section of the mud pulse telemetry valve.

A method for assembling a downhole valve, comprising:
- connecting a first tubular member having a first bore and a first end to a second end of a second tubular member having a second bore thereby fluidly connecting, via a slip joint, a pilot valve section of the downhole valve secured within the first tubular member to a tool section of the downhole valve secured within the second tubular member, the slip joint being disposed within one of the first tubular member and the second tubular member and configured to form a fluid tight connection allowing for rotational and longitudinal movement between the pilot valve section and the tool section, the pilot valve section provided with a pilot valve having a pilot valve member configured to be connected to an actuator to selectively move the pilot valve member into a closed or open position for providing a differential pressure or fluid flow through the slip joint, wherein a tool of the tool section is operable by the differential pressure or fluid flow from the pilot valve section through the slip joint;
- wherein the downhole valve is a mud pulse telemetry valve, and the tool section is a signal valve section of the mud pulse telemetry valve.
A method, comprising:
- securing a pilot valve section of a downhole valve in a first bore of a first tubular member adjacent to a first end of the first tubular member, the pilot valve section provided with a pilot valve having a pilot valve member configured to be connected to an actuator to selectively move the pilot valve member into a closed or open position for providing a differential pressure or fluid flow;
- and
- securing a tool section of the downhole valve in a second bore of a second tubular member adjacent to a second end of the second tubular member, at least one of the pilot valve section and the tool section having a tube extending beyond confines of the respective first tubular member and the second tubular member, the tube fluidly connecting the pilot valve section and the tool section such that the tool section is operable by differential pressure or fluid flow ported through the tube,
- wherein the tube is a first tube, and the other one of the pilot valve section and the tool section has a second tube, and further comprising connecting the first end of the first tubular member to the second end of the second tubular member to form a tool joint disposed within one of the first tubular member and the second tubular member, thereby also fluidly connecting the pilot valve section of the downhole valve disposed within the first tubular member to the tool section of the downhole valve with the first tube and the second tube;
- wherein the downhole valve is a mud pulse telemetry valve, and the tool section is a signal valve section of the mud pulse telemetry valve.
