Problems solved by technology

Problems inherent with these pipe guides include the space and weight of the pipe guide system and the height they add to the snubbing unit
Additionally, approximately half the effective travel of the snubbing device is lost, so snubbing operations become much less efficient than if the full snubbing travel could be performed

Abstract

A pipe guide apparatus for guiding a pipe during snubbing of the pipe includes a pair of hydraulic cylinders and cylinder rods; a stationary guide affixed between a bottom jack plate and a top jack plate, comprising a stationary pipe guide; a travelling jack plate affixed to the cylinder rods; a travelling pipe guide in sliding engagement with the cylinder rods and connected to the travelling jack plate by a lift rod. The stationary pipe guide and the travelling pipe guide each define a pipe opening and has a flexibly resilient guide member having an opening with a diameter closely matching the outside diameter of the pipe being snubbed.

Description

technical field [0001] The present invention relates to pipe guides for use in snubbing units for forcing pipe into and out of oil and gas wells And forced out of the gas well. Background technique [0002] Snubbing devices are used to feed and trip tubulars into and out of subterranean wells. Common snubbing devices include stationary snubbing slips or clamps for snubbing, and traveling snubbing slips for snubbing, so as to follow The traveling snubbing slips move toward and away from the stationary snubbing slips to alternately grip and release the pipe. [0003] Traditional pipe guides used on snubbing units today typically employ two interlocking and movable Telescoping tube. Problems inherent with these pipe guides include the space and weight of the pipe guide systems and the height they add to the snubbing rig. Additionally, about half of the effective travel of the snubbing device is lost, so snubbing operations become much less efficient than if the full snubbi...
