Method of deploying and powering an electrically driven device in a well
A system for installing a powered device in a downhole tube, comprising a power line disposed along a production tube and terminating in a first power connector and an orientation profile disposed in the vicinity of the first power connector. An assembly includes a powered device having a second power connector and an extending orientation capable of radial outward movement from the assembly. The powered device being lowered down the production tube, causing the extending orientation to be urged radially outwards to engage with the orientation profile and orient the device, so that the first power connector and second power connector engage to connect the powered device to the power line in an automatic manner.
1. A system for installing a powered device in a downhole tube, comprising:
a power line disposed along a production tube, terminating in a first power connector;
an orientation profile disposed in the vicinity of the first power connector; and
an assembly including:
a powered device including a second power connector, and
an extending orientation means capable of radial engagement in the orientation profile;
the extending orientation means being configured to be urged radially outward from the assembly responsive to the powered device being longitudinally moved along the production tube to engage the extending orientation means with the orientation profile and to orient the powered device, so that the first power connector and second power connector are aligned circumferentially to connect the powered device to the power line in an automatic manner;
wherein when the extending orientation means engages with the orientation profile, the second power connector is activated; and
wherein the second power connector is configured to move independently of the longitudinal movement of the powered device, following activation of the second power connector, radially outward, following orientation of the powered device, to a position in alignment with the first power connector.
2. A system according to claim 1 , wherein the extending orientation means is prevented from extending radially by a first restraining means in the assembly, the first restraining means being released upon the assembly reaching a predetermined depth.
3. A system according to claim 2 , wherein the release of the extending orientation means by the first restraining means is activated by a particular well pressure.
4. A system according to claim 2 , wherein there is provided inlet slots for the flow of well fluid from outside the production tube to inside the production tube.
5. A system according to according to claim 4 , wherein the production tube includes a widened inner diameter above the inlets.
6. A system according to claim 1 ,
wherein the second power connector is capable of radial outward movement from the assembly, and whose radial outward movement is constrained by a second restraining means, the second restraining means being released upon the assembly reaching a predetermined depth.
7. A system according to claim 6 , wherein the release of the second power connector is constrained by the position of the extending orientation means.
8. A system according to claim 6 , wherein there is provided inlet slots for the flow of well fluid from outside the production tube to inside the production tube.
9. A system according to according to claim 8 , wherein the production tube includes a widened inner diameter above the inlets.
10. A system according to claim 6 , wherein the second power connector moves radially outward into a window in the production tube above the first power connector.
11. A system according to claim 1 , wherein the powered device is a submersible pump and an electric motor.
12. A system according to claim 11 , wherein there is provided inlet slots for the flow of well fluid from outside the production tube to inside the production tube.
13. A system according to according to claim 12 , wherein the production tube includes a widened inner diameter above the inlets.
14. A system according to claim 1 , comprising inlet slots for the flow of well fluid from outside the production tube to inside the production tube.
15. A system according to according to claim 14 , wherein the production tube includes a widened inner diameter above the inlets.
16. A system according to claim 1 , wherein the second power connector moves radially outward into a window in the production tube above the first power connector.
17. An assembly, comprising:
a powered device including a second power connector; and
an extending orientation means capable of radial outward movement from the assembly configured to be urged radially outward from the assembly responsive to the powered device being longitudinally moved along a production tube to engage the extending orientation means with an orientation profile disposed in the vicinity of a first power connector terminating a power line disposed on the production tube to orient the powered device, so that the second power connector and the first power connector are aligned circumferentially;
wherein the second power connector is activated in response to the extending orientation means engaging with the orientation profile; and
wherein the second power connector is configured to move radially outward, independently of the longitudinal movement of the powered device along the production tube, following activation of the second power connector, and following orientation of the powered device, to engage the first power connector to connect the powered device to the power line in an automatic manner.
18. An assembly according to claim 17 , wherein the second power connector moves radially outward into a window in the production tube above the first power connector.
