ABSTRACT:
An improved emergency release tool is provided to releasably connect a coiled tubing to one or more downhole tools. The emergency release tool broadly includes a releasable slip for holding a coiled tubing, the releasable slip being secured to a first end of a slip case, the slip case being disposed within a slip housing and a lower housing, the slip housing being movable from a locked position to a released position; a piston slidably disposed about the slip case and being moveable from a locked position to a released position; a first end of the lower housing being releasably connected to a second end of the slip housing when the slip housing is in its locked position; and, a remotely activated means for moving the piston and the slip housing from their locked positions to their released positions to disengage the releasable slip from the coiled tubing and enable the coiled tubing to be removed from the tool. A quick disconnect coupler is also provided, and broadly includes a pin connector having a series of lugs; a box connector for receiving the pin connector and having a series of recesses to engage and hold the lugs inside the box connector; and, a load ring between the box connector and the pin connector for transmitting compressive loads through the connection.
