Summary of the invention
The purpose of this utility model is that operation is loaded down with trivial details, a difficult problem for time-consuming length in order to solve under current drifting, pipe cleaning tubing string twice, and a kind of logical integrated underground tool of scraping is provided, and improves efficiency of construction, reduces worker's labour intensity, shortens and accounts for the well cycle.
Technical solution of the present utility model is: a kind of logical scrape integrated underground tool and comprise drift size gauge tool and spring scraper, the lower contact of drift size gauge tool is connected with spring scraper, bottom at spring scraper connects Anti-colliding joint, realizes lower one-trip string and completes drifting, two tasks of pipe cleaning.
Compared with prior art; remarkable advantage of the present utility model is: the utility model has been installed Anti-colliding joint in the bottom of instrument; the external diameter of this Anti-colliding joint is identical with drift size gauge tool; and on Anti-colliding joint and drift size gauge tool, be all provided with chute; can realize well-flushing function; spring scraper is arranged on to the middle part of instrument, provides the protection in the process of removing by Anti-colliding joint to it.The cutter hub bottom of spring scraper and the fitting face of cutter hub pressing plate are arc fitting faces, efficiently solve existing spring scraper first sleeve pipe place below wellhead casing pipe pipe nipple and are hampered, the difficult problem that instrument cannot be gone into the well.The utility model has selected pit shaft fouling, shallow-layer to shake out and inclined shaft with large displacement and horizontal well do field experiment, proves not occur in its implementation process engineering and security incident.Successfully realize that one-trip string reaches pit shaft check and borehole wall foreign material are processed comprehensive object.In use procedure, if sleeve pipe exists foul and cover change etc., problem is hampered midway, and its tubing string all can trip out safely, and safety factor is high.Provide downhole tool for leading to, scrape integrated construction, solved current drifting, scraped that tubing working procedure is loaded down with trivial details, a difficult problem for time-consuming length, reduced execute-in-place person's labour intensity, reduced accident Probability, improved efficiency of construction.This instrument is installed simple and fast, safe and reliable, has higher promotional value.
