초록 ▼

An apparatus and method for snubbing tubing-conveyed perforating guns in and out of a well bore. The apparatus includes a string of perforating guns wherein adjacent perforating guns are attached using a connector having an upper mandrel which is attached to a lower mandrel by left-hand threaded connection. A ratchet positioned on the upper mandrel allows left-hand rotation of the upper mandrel and ratchet with respect to the lower mandrel while preventing right-hand rotation of the ratchet with respect to the lower mandrel. Shear screws interconnecting the upper mandrel and the ratchet may be sheared upon application of a predetermined torque to allow right-hand rotation of the upper mandrel with respect to the ratchet. The lower mandrel has a recess or reduced diameter portion which is adapted for sealing engagement by a pipe ram in a blowout preventer. The connector allows snubbing of a tubing-conveyed perforating gun string in and out of a well bore under pressure while utilizing existing and unmodified workover equipment and methods of snubbing the guns into the well bore and retrieving them are disclosed.

대표청구항 ▼

A method of snubbing perforating guns into a well under pressure, said method comprising the steps of: (a) closing a blind ram in a blowout preventer on said well; (b) connecting by left-hand rotation a slick joint to a perforating gun; (c) lowering said slick joint and said perforating gun into said blowout preventer; (d) closing a packoff around said slick joint; (e) opening said blind ram; (f) further lowering said slick joint and gun into said blowout preventer; (g) closing pipe rams on a connector between said slick joint and said perforating gun; (h) disconnecting by right-hand rotation said slick joint from said perforating gun; (i) raising said slick joint in said blowout preventer; (j) closing said blind ram below said slick joint; (k) opening said packoff and removing said slick from said blowout preventer; (l) connecting by left-hand rotation said slick joint to another gun; (m) lowering said slick joint and the other gun into said blowout preventer; (n) closing said packoff around said slick joint; (o) opening said blind ram; (p) further lowering said slick joint and said other perforating gun into said blowout preventer and connecting by left-hand rotation said other gun to the first-mentioned gun; (q) opening said pipe rams; (r) lowering said slick joint and said perforating guns into said blowout preventer; (s) closing said pipe rams on a connector between said slick joint and an uppermost one of said guns; and (t) repeating steps (h)-(s) as desired.
