Abstract
The utility model relates to an oil pipe scraper in pit, the utility model discloses comprise rope socket, main part and direction head, the rope socket lower extreme is threaded connection main part and direction head in proper order, and wherein the main part is the cylinder, is equipped with the heliciform slot scraping on its surface, on the surface of main part, is equipped with vertical spout, the scraper is the ring bodies, be equipped with on its ring bodies with the main part surface on the guide vane that each other corresponds of vertical spout, clamp the vertical spout on the main part surface through the guide vane with the scraper in. The overhead end that leads is the female cylinder, and the middle part is less than the cylinder of upper portion diameter for the diameter, and the lower extreme is the inside rhombus bluff body that has the through -hole. The beneficial effects of the utility model are that, it is movable from top to bottom to hinder the position through the oil pipe scraper in the chance, and to the scale deposit position carrying out preliminary treatment, when the card was met to the major diameter scraper, the accessible lifts transferred the operation greatly, made the scraper and the relative slip of main part implement the jarring unfreezing, avoided the instrument to be blocked and died, can continue to implement the siphunculus after the unfreezing and operate.
Description
Technical field
The utility model relates to the aid of oil field well oil pipe cleaning inside, the down-hole oil tube scraper especially in water injection well.
Background technology
Latter period of oilfield development, separate water injection well progressively increases, due to producing well need under enter the instrument such as throw in catcher, flow meter and instrument carries out the work such as test allotment.Because there is local scaling phenomenon in oil pipe or downhole tool, its internal diameter is reduced, or local crude oil condenses into block, the situation causing tester to be hampered in the process of going into the well often occurs.Processing method conventional is at present mainly by entering to lead to the mode of scraping instrument process under steel wire for logging, because structure design is unreasonable, when tool external diameter is larger, handling capacity is poor, and instrument is met when blocking without unfreezing function, cause the accident complicated, and adopt small diameter tools process, in tubing string after process in latus rectum be difficult to meet instrument and go into the well requirement.
ZL201420202420.3 discloses a kind of link type injection well testing drifting device, comprise rope socket, main body, ring-shaped step and cone guide head composition, although possess the function of process oil pipe or downhole tool internal incrustation, but because instrument adopts global design, without relative movement part, local is stuck then overall stuck, cannot carry out jarring releasing, therefore do not possess unfreezing function by active tool.
Utility model content
The purpose of this utility model is to provide a kind of down-hole oil tube scraper, not only can remove the incrustation scale of pipe string internal wall attachment and stick thing, simultaneously when logical curette, realizing unfreezing function by upper and lower handling tubing string, improving siphunculus success rate.
The technical scheme that the utility model adopts is: the utility model is made up of rope socket, main body and guide head, and rope socket lower end is threaded main body and guide head successively, and wherein main body is cylinder, and its external surface is provided with helical form slot scraping.
On the external surface of described main body, be provided with longitudinal chute; Scraper is ring bodies, and its ring bodies is provided with the guide vane mutually corresponding with the longitudinal chute on body outer surface, to be installed on by scraper in the longitudinal chute on body outer surface by guide vane.
The chute of described body outer wall is preferably 3 or 4, matches with the guide vane of scraper.
The longitudinal section of the guide vane lateral surface of described scraper is isosceles trapezoid shape.
Described guide head upper end is female cylinder, and middle part is the cylinder that diameter is less than upper diameter, and lower end is the rhombus bluff body that there is through hole inside.
The beneficial effects of the utility model are, up and down in the position that is hampered by oil pipe scraper, chute in main body carries out preliminary treatment to fouling position, large diameter scraper can continue to expand passage, when card met by major diameter scraper, by raising and decentralizing operation, the relative sliding of scraper and main body is made to implement jarring releasing, avoid instrument to be stuck, can continue after unfreezing to implement siphunculus operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the half sectional view of scraper 2 of the present utility model.
Fig. 3 is the top view of scraper 2 of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to accompanying drawing, the utility model is made up of rope socket 1, main body 3 and guide head 4, and rope socket 1 lower end is threaded main body 3 and guide head 4 successively, and wherein main body 3 is cylinder, and its external surface is provided with helical form slot scraping 31.
On the external surface of described main body 3, be provided with longitudinal chute 32; Scraper 2 is ring bodies, and its ring bodies is provided with the guide vane 21 mutually corresponding with the longitudinal chute on main body 3 external surface, to be installed on by scraper 2 in the longitudinal chute 32 on main body 3 external surface by guide vane 21.
The chute 32 of described main body 3 outer wall is preferably 3 or 4, matches with the guide vane 21 of scraper 2.
The longitudinal section of guide vane 21 lateral surface of described scraper 2 is isosceles trapezoid shape.
Described guide head 4 upper end is female cylinder, and middle part is the cylinder that diameter is less than upper diameter, and lower end is the rhombus bluff body that there is through hole 41 inside.
When separate layer water injection string test be hampered need carry out siphunculus process time, to be connected with rope socket 1 by steel wire for logging and in oil pipe behind the position that is hampered, carry on the ground and drive down-hole scraper to move up and down with lowering operation, the dirt of the slot scraping 31 pairs of pipe string internal walls in the less main body of main body 3 lower diameter or oil clot is utilized to carry out progressively scraping, expand passage gradually, the larger scraper 2 of diameter processes, further until scraper is smoothly by the position that is hampered simultaneously.When card met by the scraper 2 that diameter is larger, because main body 3 and scraper 2 can relative motions, by lowering operation is carried on ground, the energy utilizing the weight of main body 3 and speed to produce can carry out jarring releasing to scraper 2, then continue to process the position that is hampered, when scraper can smoothly by be hampered position time, instrument can be met by requiring.
