A fully automatic oil well workover rod and pipe operation industrial robot

Abstract

The invention discloses a fully automatic oil workover rod and pipe operation industrial robot. The robot includes a main rod and pipe processing mechanism, a rod and pipe stacking mechanism, a rod and pipe conveying device, an auxiliary hydraulic oil pipe slip, a sucker rod slip, a rod Pipeline flaw detection device and GPS positioning device; the main rod and pipe processing mechanism includes the main chassis, guide rail device and mechanical arm device; the rod and pipe palletizing device is equipped with a palletizing base, a moving mechanism and a manipulator device; The cross arm of the oil pipe and sucker rod, the rod pipe delivery device includes delivery device 1 and delivery device 2; The length measuring device, the second conveying device is located at the front end of the rod and pipe stacking mechanism, and is on the same straight line as the conveying device one to realize the transmission of oil pipes and sucker rods.

Description

technical field [0001] The invention relates to the technical field of intelligent control of oil well workover equipment, in particular to an industrial robot for fully automatic oil well workover rod and pipe operations. Background technique [0002] In the process of oil field production, when the production is reduced or stopped due to oil well or equipment failure, or when the working conditions of the oil well change and the production process measures need to be changed according to the new situation, the workover operation must be carried out on the oil well. For example, when changing from a gushing well to a pumping well, changing the running depth and model of the oil well pump, or encountering oil pipe leakage, sucker rod fracture, etc., it is necessary to lift and lower the oil pipe for workover operations. These tasks usually need workover rig equipment to complete. The original wellhead workover rig in the prior art is composed of at least 4-6 people on site ...

AI Technical Summary

Problems solved by technology

Although the technology disclosed in this document reduces the labor intensity of manually draining oil and casing on site to a certain extent, the number of wellhead operators has not been reduced

Another example is the invention patent document with the application number of 201210370190.7 disclosing a semi-automatic tubing manipulator equipped with a tubing pick-up and delivery slideway, relying on the remote control method to realize the open-loop control workover operation automation production line, but it still does not fundamentally reduce the labor intensity of workers , improve operating efficiency, and the configuration of the number of well crews has not changed

Another example is the invention patent document with application number 201410584164.3, which discloses a workover operation auxiliary machine with a skid-mounted base and a transmission device, which improves the automation of workover operations, but its main body can only temporarily store a certain number of tubing pumps. The oil rod does not have the ability to handle all sucker rods and oil pipes, and the invention does not have special equipment for lifting and dismantling the sucker rods, and does not realize fully automatic workover operations for all oil pipes and sucker rods
