Description
Technical Field
The utility model relates to a technical equipment that uses during pumping well maintenance in the oil development field, specifically speaking relate to an oil pipe inner wall washs scraping means.
Background
In the prior art, the oil pipe inner wall cleaning scraping tool is provided with a scraping body, a scraper is fixedly arranged on the scraping body, the upper part of the scraping body is in threaded connection with an anchor body, the lower part of the scraping body is in threaded connection with a spray head, a spray channel communicated with the spray head is formed in the scraping body, and a water injection hole communicated with the spray channel is formed in the anchor body.
When the inner wall of the oil pipe is cleaned and scraped by using the cleaning and scraping tool for the inner wall of the oil pipe, the sucker rod and the plunger are lifted to the outside of a well head, then the cleaning and scraping tool for the inner wall of the oil pipe is put into the oil pipe, the plunger pump is started, the cleaning and scraping tool is pushed to the bottom of the oil pipe at a certain speed from a pipe opening by using 80-DEG clean water at a displacement of 200 liters/minute, the cleaning and scraping tool is in a descending process, on one hand, the 80-DEG clean water is sprayed out from a spray head to clean the inner wall of the oil pipe, meanwhile, a scraper on the cleaning and scraping tool is in contact with the inner wall of the oil pipe to scrape and clean the inner wall of the oil pipe, and the cleaning and scraping tool enters the.
The main problems of the cleaning and scraping tool for the inner wall of the oil pipe in the prior art are as follows: the scraping body is of an integrated structure, the scraper on the scraping body is worn after the oil pipe is cleaned once and cannot be reused, and the scraping body needs to be replaced integrally again at the moment, so that waste is caused, and the maintenance cost is high; in addition, the spray head is connected with the lower part of the scraping body through threads, and the phenomenon that the spray head loosens or falls off sometimes occurs when the cleaning scraping tool descends, so that the cleaning failure of the inner wall of the oil pipe is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an oil pipe inner wall washs scraping tool, the utility model discloses the cost of replacement is lower after the scraper wearing and tearing on the well scraping body.
For solving the technical problem, the utility model discloses an oil pipe inner wall washs scraping tool has the scraper body, scrapes and is equipped with the scraper on the body, and the upper portion threaded connection who scrapes the body has the anchor body, and the lower part threaded connection who scrapes the body has the shower nozzle, scrape internal being formed with the shower nozzle is linked together sprays the passageway, sets up the water filling hole that is linked together with spraying the passageway on the anchor body, the body of scraping comprises the tubulose scraper body that is located upper portion and the tube-shape connector that is located the lower part, and threaded connection between body and the tube-shape connector is scraped to the tubulose, the tubulose scraper body with its upper portion with anchor body threaded connection, the tube-shape connector with its lower part with shower nozzle threaded connection, scraper suit on the tubulose scraper body.
As an improvement of the utility model, be located the cover is equipped with the backing ring on the tubulose scraping body between scraper and the tube-shape connector, and the cover is equipped with the clamping ring on the tubulose scraping body that is located between scraper and the anchor.
As a further improvement of the utility model, the outer wall of the spray head is provided with an inner hexagonal cone end fastening screw for preventing the relative rotation of the spray head and the tubular connector.
By adopting the oil pipe inner wall cleaning and scraping tool with the structure, the scraping body consists of the tubular scraping body positioned at the upper part and the tubular connecting body positioned at the lower part, the tubular scraping body and the tubular connecting body are in threaded connection, the upper part of the tubular scraping body is in threaded connection with the anchor body, the lower part of the tubular connecting body is in threaded connection with the spray head, and the scraper is sleeved on the tubular scraping body, so that the scraper can be taken down from the tubular scraping body to be independently replaced when the scraper is worn, the scraper does not need to be integrally replaced together with the scraping body, and the maintenance cost is reduced; after the technical characteristics that the tubular scraping body positioned between the scraper and the tubular connecting body is sleeved with the supporting ring and the tubular scraping body positioned between the scraper and the anchor body is sleeved with the pressing ring are further adopted, the scraper can be prevented from moving up and down and being abraded on the end faces of the tubular connecting body and the anchor body; after the inner hexagonal cone end fastening screw for preventing the nozzle and the cylindrical connecting body from rotating relatively is arranged on the outer wall of the nozzle, the relative rotation of the nozzle and the cylindrical connecting body can be effectively prevented, and the nozzle is prevented from loosening and falling off.
