A device for cleaning and blowing down oil sucker rods and its usage method

Abstract

The invention relates to a cleanout and blowdown device for oil pumping pipes and rods and a using method thereof. A slit clearing spiral conveyer is arranged at the bottom of a tank body, a pipe and rod pushing spiral conveyer is arranged on one side of the cavity of the tank body, a pipe and rod lifting spiral conveyer is arranged on the other side of the cavity of the tank body, and a pipe and rod feeding roller is arranged at the inlet in the top of the tank body. The pipes and rods are conveyed into the tank body through the pipe and rod feeding roller and arranged in grooves of the pipe and rod pushing spiral conveyer through a pipe and rod discharging tool extractor in sequence until the pipes and rods are arranged on a pipe and rod discharging roller at the top of the pipe and rod lifting spiral conveyer. Oil stains on the outside of the pipes and rods are washed away by high-temperature and high-pressure water through pipe and rod external washing spraying nozzles, and oil stains in the pipes and rods are washed away through pipe and rod internal washing spraying nozzles. The cleanout and blowdown device has the advantages that oil removal and blowdown can be achieved with no need to shut down devices, cleanout efficiency is increased, and cost is reduced. Furthermore, by means of the hot water soak cleaning technology, soaking time of the oil pumping pipes and rods is prolonged effectively, oil stains on the oil pumping pipes and rods can be softened fully, and cleaning quality and efficiency are increased.

Description

technical field [0001] The invention relates to a cleaning device and method for an oil sucking pipe rod, in particular to a cleaning and sewage discharge device for an oil sucking pipe rod and a use method. Background technique [0002] At present, in oil field production, oil pipes and sucker rods need to undergo pressure testing, flaw detection, straightening and repairing, heat treatment, etc. before they are put into use, and oil stains need to be cleaned before this. The waxy layer in the tubing generally ranges from 1 mm to all wax plugging, and wax removal requires cleaning all the wax on the inner and outer walls of the tubing. Most of the existing oil pipe and rod cleaning devices are composed of transmission mechanism, heating system flushing equipment, etc. These equipment are installed in a rectangular airtight container, and the transmission mechanism is fork rotation. The existing problems are: the transmission is not stable, and the pipe is easy to be stuck ...

AI Technical Summary

Problems solved by technology

Most of the existing oil pipe and rod cleaning devices are composed of transmission mechanism, heating system flushing equipment, etc. These equipment are installed in a rectangular airtight container, and the transmission mechanism is fork rotation. The existing problems are: the transmission is not stable, and the pipe is easy to be stuck , the cleaning efficiency is low, and maintenance is relatively difficult; the flushing equipment only has internal flushing, and the external cleaning of oil pipes and rods relies on the staff on duty to hold high-pressure spray guns. Not only the cleaning quality is poor, but also there are potential safety hazards and easy to cause environmental pollution
