Control system of righting hand in oil field workover operation

Abstract

The invention discloses a righting hand control system for oil field workover operations, which solves the problem that the wellhead stabbing of the platform manipulator in the prior art cannot be accurately completed. The righting hand control system for oil field workover operations includes the following steps: 1) initialization of the righting hand; 2) manual signal detection; When the oil pipe is detected by the hand, the righting hand is closed, and a signal is sent to the platform manipulator to retract. The oil pipe is put into the box, and the driller gives the signal, and the righting hand is opened and retracted, and the main program ends; 6) The righting hand is opened and extended to the position of the lift, When the righting hand detects the retraction signal, the righting hand retracts, and the main program ends; 7) The righting hand opens and extends to the position of the lift, the righting hand detects the oil pipe, the righting hand retracts to a certain position, closes, and continues to retract When the wellhead is reached, the tubing is put into the box, the driller gives a signal, the righting hand is opened and retracted, and the main program ends.

Description

technical field [0001] The invention relates to the technical field of oilfield workover equipment, in particular to a righting hand control system capable of improving work efficiency and work safety. Background technique [0002] Well workover operation refers to a kind of operation of oil drilling and subsequent oil well maintenance, in order to ensure the smooth use of oil wells, maintenance and maintenance measures are taken. Workover operations are characterized by high engineering difficulty and high technical requirements. Large workover equipment must be equipped with special equipment and tools such as overhaul drill pipes and overhaul turntables to carry out work. In the workover operation in the prior art, the most common work content includes tripping out and tripping in. Drilling, as the name suggests, is to lift the downhole drilling tool (such as tubing) out of the wellbore; Drilling, as the name suggests, is to lower the drilling tool into the wellbore. ...
