Continuous trip drill rig pipe treatment system

Abstract

The invention discloses a continuous trip drill rig pipe treatment system. The continuous trip drill rig pipe treatment system comprises a pulley rail and a pulley which are installed on a derrick, a sliding jacking hydraulic cylinder and a sliding beam are installed on a pulley rack, the top end of the pulley rack is hinged to the top end of a lifting rack, and the bottom end of the lifting rack is hinged to the top end of a front stand column a supporting sliding frame. A continuous rotating iron roughneck and a front opening power slip are installed in the supporting sliding frame, and a supporting rod is hinged between the front stand column and a sliding beam of the supporting sliding frame. A lifting cable head is installed in the middle of the lifting rack. According to the continuous trip drill rig pipe treatment system, in the continuous tripping operation process, the continuous rotating iron roughneck and the front opening power slip can alternately enter and exit from the center line position of a well mouth with a top drive system according to the pipe operation requirement; a dynamic pipe column can be suspended, a dynamic pipe connector can be subjected to continuous screwing-on and screwing-off, and efficient treatment of the operation process such as mud recycling can be achieved, and the operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of drilling and production equipment, in particular to a pipe tool processing system for a continuous tripping drilling rig. Background technique [0002] The tripping operation is a very important operation link in the drilling process of oil and gas development. It refers to connecting a single drill pipe or a vertical root to the top of the drill string in the well during the drilling process for the next stage of drilling operations, or at the end of drilling. The operation process of taking the drilling tool out of the wellbore. The tripping process of the traditional drilling method is as follows: the top drive holds the drill pipe collar at the top of the drill string through the elevator connected under its lifting ring, and the drilling rig hoist system lifts the top drive to lift the drill string in the well by a single or vertical drill string. height, the hoisting system stops to continue hoisti...

Problems solved by technology

[0003] In the tripping operation in the traditional drilling process, when switching between various operating links, the operating device in the previous operating link needs to release the operating object and reset to release the occupation of the operating position after the operating device in the previous operating link completes the task. The operating device in one operation link needs to carry out necessary work preparations and positioning actions. Each link is operated in series, and the entire operation process is intermittent and discontinuous. The operation takes a long time and the operation procedures are complicated, which is prone to misuse and other disadvantages.
