Abstract
A downhole tool position adjustment assembly for locating a tool downhole comprising a mandrel coupled to a housing via an extend-retract mechanism. A controller communicatively connected to the extend-retract mechanism, wherein an application executing within the controller, is configured to control the extend-retract mechanism. A communication system, communicatively coupled to the controller, is configured to receive a command signal from an operator at a surface location. The extend-retract mechanism moves the mandrel relative to the housing in response to a control signal received from the controller in response to the command signal received by the communication system.
Claims28
A downhole tool position adjustment assembly, comprising:
- a mandrel 114 coupled to a housing 112 by an extend-retract mechanism, wherein actuation of the extend-retract mechanism moves the mandrel 114 relative to the housing 112;
- a perforating gun assembly coupled to the mandrel;
- a controller 138 communicatively connected to the extend-retract mechanism;
- and
- a communication system 140, communicatively connected to the controller 138 and configured to receive a command signal transmitted by an operator at a surface location,
- wherein the controller is configured to send a control signal to actuate the extend-retract mechanism in response to the command signal received by the communication system 140 and
- wherein the perforating gun assembly is moved to a target zone in response to the movement of the mandrel relative to the housing.
A method of positioning a downhole tool assembly, comprising:
- conveying a downhole tool coupled to an adjustment tool into a wellbore on a work string, wherein the adjustment tool comprises a mandrel, a housing, an extend-retract mechanism, wherein the extend-retract mechanism couples the mandrel to the housing, and wherein the downhole tool is coupled to the mandrel;
- measuring a distance from the downhole tool to a target zone;
- signaling the adjustment tool with a command signal;
- and
- moving the downhole tool from a first position to a second position located within the target zone in response to the mandrel moving relative to the housing, by the extend-retract mechanism, in response to the command signal;
- and
- unlocking a packer actuation assembly 180 on a service packer 170, wherein the packer actuation assembly 180 comprises a lug lock 158 in a first position retaining a lug in a run-in position within a j-slot, and wherein the mandrel moving relative to the housing moves the lug lock 158 to a second position, and wherein the lug is released to a second position within the j-slot in response to the lug lock 158 moving to the second position.
A downhole tool position adjustment assembly, comprising:
- a mandrel 114 coupled to a housing 112 by an extend-retract mechanism, wherein actuation of the extend-retract mechanism moves the mandrel 114 relative to the housing 112;
- a service packer 32 comprising a sealing element, a set of slips 42, a drag block assembly 44, and a packer actuation assembly comprising a lug and a i-track, wherein a first position of the lug in the i-track retains the service packer 32 in a run-in position and a second position of the lug in the i-track allows the service packer 32 to actuate, wherein the service packer 32 is coupled to the housing 112 and wherein the mandrel 114 is coupled to the housing 112 by the extend-retract mechanism;
- a controller 138 communicatively connected to the extend-retract mechanism;
- and
- a communication system 140, communicatively connected to the controller 138 and configured to receive a command signal transmitted by an operator at a surface location,
- wherein the controller is configured to send a control signal to actuate the extend-retract mechanism in response to the command signal received by the communication system 140.
