Description
Technical field
The utility model belongs to the down-hole workover tool that petroleum industry uses, particularly a kind of underground work is logical scrapes integrated tool, being applicable to oil field to bring in a well in operation and various measure operation process to the drifting of oil, gas, well sleeve pipe and sleeve pipe scraping, is particularly useful for the workover treatment of oilfield horizontal well.
Background technology
Horizontal well because having exclusive advantage on raising Exploitation Level of Oilfield, and application is more and more.Run through casing size detects, sleeve pipe scraping is conventional operation in oil well repairing operation, and object is the intact degree of checking run through casing size, and the main tool completing this operation is drift size gauge tool and spring sleeve pipe pipeline scraper.To implement before pipe cleaning advanced person to work well, during scraping pipeline scraper blade under the action of the spring with internal surface of sleeve pipe close contact, the mud cake on scraping internal surface of sleeve pipe, salt-pepper noise, perforation burrs etc.
Due to the casing programme that horizontal well is special, there is very large construction risk during major diameter tool operation, drifting, pipe cleaning two procedures job execution cycle are long, and operating cost is high.At present in straight well operation, for improving drifting pipe cleaning operation timeliness, generally adopt a kind of leading to scrape integration tool, this instrument needs pitching to open scraping blade, but when horizontal well operation, ball can not set very well at net horizontal section
,cause scraping blade not opened, sleeve pipe scraping can not be completed.Therefore, be well workover treatment timeliness and the safety factor of improving the standard, need a kind ofly to exempt from the logical of ball-throwing type and scrape integration tool.
Summary of the invention
The purpose of this utility model is that providing a kind of underground work to lead to scrapes integrated tool, once go into the well during oilfield horizontal well well workover is constructed and can realize run through casing size detection and internal surface of sleeve pipe scraping two procedures, effectively to improve the standard the efficiency of construction of the special structure well such as well, high angle hole, reduce horizontal well operating risk.
The purpose of this utility model is achieved in that
A kind of underground work is logical scrapes integrated tool and comprises top connection and housing, top connection is threaded with housing, housing is built with choke valve, piston and scraping block, choke valve is contained in the top of piston, between piston and housing, spring is housed, scraping block is bolted in the shell wall of housing, and scraping block coordinates with the bottom of piston.
Described choke valve comprises valve body and needle, and needle is cylinder, is provided with the centre bore that internal diameter is below 20mm, is connected, between valve body and housing, sealing ring is housed by screw thread with valve body.
Described upper piston area is piston body, and piston body cylindrical is provided with sealing ring, and spring is located between piston rod below piston body and the inner circle shoulder of housing; The top inner circle of piston body coordinates with the bottom cylindrical of throttling pin, and the bottom cylindrical of piston rod is two connected lower inclined tapers, and being connected at two is provided with the inner arc respective outer side edges of limiting platform and scraping block between lower inclined taper.
Compared with the drifting of current oil field operation, scraper, remarkable result of the present utility model is: the utility model, by hydraulic control choke valve, makes the centre bore of the throttling pin shutoff piston of choke valve, promotes piston and moves down and released outside housing by scraping block.Needing the well section of carrying out scraping, just pressurizeing with pump truck just can spreading scraping block, and scraping is complete, scraping block automatic drawing back after pressure release.Housing outer diameter of the present utility model is identical with conventional drift size gauge tool, can be used for run through casing size, scraping block is used for the scraping of internal surface of sleeve pipe, do not need pitching setting, solve the problem of the setting difficulty of net horizontal section pitching, once go into the well and namely can complete drifting, scraping two procedures, operating efficiency is high, and operating risk is little.Its advantage is embodied in: 1, shorten operation and account for the well cycle, improve operating efficiency, once go into the well and can complete drifting, pipe cleaning two procedures.2, reduce horizontal well job execution risk, decrease the go into the well number of times of workover tool in horizontal well.3, reservoir protec-tion, avoids major diameter instrument and repeatedly to go into the well the formation sand production caused.4, this instrument can be recycled and saves production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in detail below in conjunction with accompanying drawing, and unrestricted protection domain of the present utility model.
See Fig. 1, a kind of underground work is logical scrapes integrated tool and comprises top connection 1 and housing 2, top connection 1 is threaded with housing 2, housing 2 is built with choke valve 3, piston 7 and scraping block 8, choke valve 3 is contained in the top of piston 7, spring 6 is housed between piston 7 and the inner circle shoulder of housing 2, and scraping block 8 is fixed in the shell wall of housing 2 by bolt 9, and scraping block 8 coordinates with the bottom of piston 7.Choke valve 3 comprises valve body and needle 4, and needle 4 is cylinders, is provided with the centre bore that internal diameter is below 20mm, is connected, sealing ring 5 is housed between valve body and housing 2 by screw thread with valve body.Piston 7 top is piston body, and piston body cylindrical is provided with sealing ring 5, and spring 6 is located between piston rod below piston body and the inner circle shoulder of housing 2; The top inner circle of piston body coordinates with the bottom cylindrical of throttling pin 4, and the bottom cylindrical of piston rod is two connected lower inclined tapers, and being connected at two is provided with the inner arc respective outer side edges of limiting platform and scraping block 8 between lower inclined taper.Housing 2 at least arranges three scraping blocks and ejects window on a horizontal plane, and the underpart of the piston rod of piston 7 at least arranges three scraping blocks 8 and forms one group of scraping mechanism on a horizontal plane.The underpart of the piston rod of piston 7 at least arranges one group of scraping mechanism, and the scraping block 8 of each group scraping mechanism is crisscross arranged in the axial direction.The middle part extrados of scraping block 8 is provided with scraping tooth.The bottom cylindrical of housing 2 is provided with drift size gauge tool junction button 10 and is connected with drift size gauge tool, can form lengthening drift size gauge tool, may be used for special lengthening drifting operation.
This instrument is connected to G.I.H on tubing string, completes and constructs to the drifting of well in operation.Needing the well section of scraping, add hydraulic pressure with pump truck in oil pipe, because the centre bore aperture of throttling pin 4 is little, under the effect of throttling pin 4, piston 7 moves down the radial spreading of promotion scraping block 8 and contacts with internal surface of sleeve pipe.Pump truck keeps hydraulic pressure constant, completes construct to the scraping of well in operation internal surface of sleeve pipe by raising and decentralizing tubing string.Scraping is complete lays down hydraulic coupling, piston 7 under the effect of spring 6 on move, scraping block 8 is recovered in housing 2 thereupon.If the long drift size gauge tool drifting of construction requirement, connects drift size gauge tool by drift size gauge tool junction button 10, form lengthening drift size gauge tool and can meet special operation requirement.
