Detailed description of the invention
As shown in Figure 2, novel dredging, scraping wall one operation drift size gauge tool, have the cylindrical shell 2 of a top with connecting thread, below opening, cylindrical shell 2 top is connected with fittings body 1 by connecting thread; It is characterized in that a hollow section being housed as guide shoe 3 in the middle of cylindrical shell 2, and cylindrical shell 2 bottom is enclosed within the step of guide shoe 3 bottom, cylindrical shell 2 top is connected with fittings body 1.The cavity empty place formed at body upper/lower terminal and the guide shoe 3 of cylindrical shell 2 is processed with duct that a circle circulates for liquid as bypass circulation port 4.Be connected as a single entity by the step on fittings body 1 and fittings body 1 on guide shoe 3 top.
As shown in Figure 3, the novel dredging, scraping wall one working string made with above-mentioned drift size gauge tool, it is connected with hydraulic pressure wall scraper by sliding sleeve switch and forms on the fittings body of described novel dredging, scraping wall one operation drift size gauge tool.
Novel drift size gauge tool adds a hollow guide shoe again in the middle of thin-wall barrel, and urceolus is enclosed within the step of guide shoe bottom, and top is connected with top connection again.The cavity empty place formed at the upper and lower two ends of body and guide shoe processes again the duct of a circle liquid-circulating, well compensate for the problem that between body and sleeve pipe, the cyclic space is little, effectively reduces the generation of lock of tool drilling.And, this novel drift size gauge tool and we research and develop successful novel All-in-One operation hydraulic pressure wall scraper with the use of, in the process of going into the well, drift size gauge tool does not verify downhole conditions, the scraper of wall scraper is not also opened, the foreign material preventing the scraper when downhole conditions is failed to understand to scrape cause the situation of bit freezing to drift size gauge tool, preferably resolve the problem of easy bit freezing common drift size gauge tool combines institutional operation during with wall scraper, thus reduce one trip operation, effectively improve operating efficiency, reduce operating cost.When after drifting operation completes and after verifying the situation of down-hole casing, now tubing string need not be tripped out, and only need drop into sealed steel ball to tubing string internal diameter, when seal drop to be positioned at suppressing on sliding sleeve below wall scraper, above drift size gauge tool time, during by being pressurized to a specific force value in tubing string, scraper is opened, now just by put and put tubing string and carry out scraping wall operation.
Cylindrical shell and the top sub of the novel drift size gauge tool of this novel All-in-One operation are screw connection structure, the below of top sub body relies on screw thread to be connected with guide shoe again, except the normal circulation passage between entire body external diameter and sleeve pipe, in cavity between cylindrical shell and guide shoe, dependence is processed the circulation port in side, cylindrical shell upper and lower two ends and defines the new circulation canal of another one, the cylindrical shell of this special construction and guide shoe structure design not only ensure that the connection reliability of several part, and the function of drifting is identical with drift size gauge tool conventional in the past.The hollow guide shoe structure increased, the connection of cylindrical shell is located more safe and reliable, and the taper structure design of guide shoe front end can also guide tubing string to be positioned at cannula center position, the situation preventing cylindrical shell premature harm He break; Cylindrical shell descends two ends oblique surface machining to have multiple circulation port thereon, to ensure in operation process, except from except the circulation canal between cylindrical shell external diameter and internal surface of sleeve pipe, to add second circulation canal, can well prevent the generation of lock of tool drilling.
