Description

Steam spray-washing device for underground oil pipe cleaning system

The technical field is as follows:

the utility model belongs to the technical field of oil field production facility, concretely relates to steam jetter for oil pipe cleaning system in pit.

Background art:

after the oil pipe of the oil production well is used for a long time, the oil pipe needs to be replaced or repaired, and a new oil pipe needs to be replaced for the oil pipe which is seriously corroded or damaged. And the oil pipe with low corrosion or damage degree can be continuously used after being repaired, such as corrosion prevention or thread-button repair. Compared with the replacement of a new oil pipe, the cost for repairing the oil pipe is low, and the method is economical and applicable. The oil pipe after the oil production well operation is pumped needs to be transported to a pipe repair factory for oil pipe repair. After the oil pipe of the oil production well is used for a long time, the inner wall of the oil pipe can be deposited with dirt substances such as silt dirt, wax dirt, oil sludge and the like to different degrees, and the outer wall of the oil pipe can be deposited with the oil sludge. Therefore, before the operation of repairing the oil pipe, the inner wall and the outer wall of the oil pipe need to be cleaned and descaled to remove the dirt and the oil sludge. At present, the inner wall and the outer wall of an oil pipe are repeatedly washed through hot washing, whether oil sludge or dirt on the inner wall and the outer wall of the oil pipe is completely removed or not is repeatedly observed in the repeated hot washing process, if the dirt such as the oil sludge is not completely washed, the oil pipe needs to be continuously and repeatedly washed until the inner wall and the outer wall of the oil pipe meet the repairing requirement, and then the hot washing is stopped. The dirt and scale cleaning mode for repeatedly and thermally cleaning the oil pipe has extremely low efficiency, and the cleaning effect and quality are poor, so that the production efficiency is greatly influenced. Therefore, it is particularly important to design a cleaning system which can clean and remove silt dirt, wax dirt and oil sludge on the inner wall of the underground oil pipe and oil dirt on the outer wall. Therefore, it is necessary to design a high-quality and high-efficiency steam spraying device for removing the outer wall sludge in the underground oil pipe cleaning system.

The utility model has the following contents:

the invention aims to provide a high-quality and high-efficiency steam spray washing device for removing the dirt on the outer wall in a downhole oil pipe cleaning system, the spray washing device can clean at least 6 oil pipes at a time, the dirt on the outer wall of the oil pipe can be effectively removed through steam, and the efficiency and the quality of cleaning and descaling the oil pipe are improved. The structure design is reasonable, the economy is suitable for, and the popularization and the use on a large scale are easy.

The technical scheme adopted by the novel method is as follows: a steam spray-washing device for a downhole oil pipe cleaning system comprises a steam boiler, a header, a steam spray pipe and a plurality of steam spray heads; the steam outlet pipe of the steam boiler is respectively welded with the main steam pipe and the steam dividing pipe through a tee joint, the steam dividing pipe and the main steam pipe are provided with valves, and the steam dividing pipe is welded with the header pipe; the steam injection pipes are positioned above the oil pipes, are communicated with the uniformly distributed steam injection heads through branch pipes, are welded and communicated with the header, and are at least 6 in number and positioned on the pipeline bracket; the oil pipe is placed on the pipe frame.

Further, the pipe frame comprises a support steel frame and at least 3 oil pipe placing plates which are welded into a whole, and the oil pipe placing plates are welded at the top end of the support steel frame; the oil pipe placing plate is provided with at least 6 arc-shaped grooves for placing oil pipes, and two ends of the oil pipe placing plate are welded with stop pins; the bottom of the supporting steel frame is welded with a base plate, the base plate is provided with foundation bolt mounting holes, and the supporting steel frame is fixed on the ground of a cleaning workshop through foundation bolts.

Further, the bottom of the pipeline bracket is welded with a base plate, the base plate is provided with foundation bolt mounting holes, and the pipeline bracket is fixed on the ground of a cleaning workshop through foundation bolts.

This neotype beneficial effect: the cleaning system can clean at least 6 oil pipes at one time, clean and descale the inner wall of the oil pipe through the cavity jet cleaning device, the steam cleaning device and the alkali cleaning device, and can effectively remove silt dirt, wax dirt and oil sludge on the inner wall; the dirty oil sludge on the outer wall of the oil pipe can be effectively removed through the steam spray washing device; the cleaning system can clean and descale the oil pipe before repairing the oil pipe at one time, so that the efficiency and the quality of cleaning and descaling the oil pipe are improved. The structure design is reasonable, the economy is suitable for, and the popularization and the use on a large scale are easy.
