Methods and Systems for Orienting a Tool in a Wellbore

摘要

Methods and assemblies that can be used to orient a second pipe with respect to a first pipe in a wellbore are disclosed. The first pipe may be a casing string that includes one or more recessed latch couplings, and the second pipe may be a tubing string that includes one more complementary radially extendable latch keys that may be received within the latch couplings. The tubing string may include one or more switches associated with the latch keys that are actuated when the latch keys are received within the latch couplings. The actuation of the switches is communicated to an operator at the surface via control lines within the tubing string.

主权项

1. A system capable of being disposed in a wellbore, the system comprising:
a first pipe having a wall a portion of which defines a target, the wall defining an inner region; a second pipe capable of being disposed in the inner region of the first pipe, a portion of the second pipe having a second pipe wall a portion of which defines a target; a device carried by at least one of the first pipe or second pipe and capable of preventing constraining relative movement of the two pipes at least rotationally or axially; a switch coupled to said device so as to actuate when the device is in a particular configuration; and a circuit operatively coupled between said switch and an indicator for notifying an operator of the configuration of said switch.
