Abstract
The utility model relates to a kind of waterpower driven rotary scraping drifting device used in oil well repairing operation.Main purpose, in order to thoroughly remove the dirt in eccentric injection mandrel passage, shortens the drifting time.This water conservancy rotates scraping drifting device and mainly comprises and rotate top connection and connected main shaft, and wherein, described main shaft fixed light cage type scraper and rhombus scraper successively from top to bottom, the lower end of main shaft connects turbine.This waterpower driven rotary scraping drifting device effectively can remove the dirt in eccentric injection mandrel passage, improves efficiency of removing contamination, and reduces cost of production.
Description
Technical field
The utility model relates to a kind of waterpower driven rotary scraping drifting device used in oil well repairing operation.
Background technology
Along with the oil-field flooding time limit increases, down-hole string scale formation is more and more serious, and eccentric injection mandrel passage internal cause dirt, dead oil are more, cause internal diameter to diminish, and after the instruments such as test, pulling are gone into the well, meets card phenomenon herein and increases.And water injection well scraping drifting device conventional is at present due to structure, injection well downhole flow regulator channel interior dirt thoroughly cannot be removed.
Utility model content
In order to thoroughly remove the dirt in eccentric injection mandrel passage, shorten the drifting time, the utility model provides a kind of waterpower driven rotary scraping drifting device.This waterpower driven rotary scraping drifting device effectively can remove the dirt in eccentric injection mandrel passage, improves efficiency of removing contamination, and reduces cost of production.
The technical solution of the utility model is: a kind of water conservancy rotates scraping drifting device, mainly comprise and rotate top connection and connected main shaft, wherein, described main shaft fixed light cage type scraper and rhombus scraper successively from top to bottom, the lower end of main shaft main shaft connects turbine.
Above-mentioned bird-caging scraper external diameter and rhombus scraper external diameter difference are greater than zero; Above-mentioned bird-caging scraper, rhombus scraper and all adopt screw fastening between turbine and main shaft; The fin of above-mentioned lantern scraper adopts spring steel to make.
The utility model has following beneficial effect: pass through the rotation just scraping of rhombus scraper and the dark scraping of secondary of lantern scraper in such scheme, thoroughly remove the dirt in injection well downhole flow regulator.Instrument is gone into the well in process, under the percussion of the inner waterpower of tubing string, worm gear is rotated and drives main axis, thus drive rhombus scraper and lantern scraper to rotate, static scraping is become dynamic rotary scraping, thoroughly removes the dirt in injection well downhole flow regulator, improve efficiency of removing contamination, reduce cost of production.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1-rotates top connection, 2-main shaft, 3-bird-caging scraper, 4-rhombus scraper, 5-turbine, 6-screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this water conservancy rotates scraping drifting device and mainly comprises the main shaft 2 rotating top connection 1 and be threaded with it, and wherein, described main shaft 2 fixed light cage type scraper 3 and rhombus scraper 4 successively from top to bottom, the lower end of main shaft 2 connects turbine 5.
The external diameter of above-mentioned bird-caging scraper 3 and the external diameter difference of rhombus scraper 4 are greater than zero, this optimization scraper structure, make it form secondary scraping mode, thoroughly remove the dirt in injection well downhole flow regulator.
Above-mentioned bird-caging scraper 3, rhombus scraper 4 and all adopt screw 6 fastening between turbine 5 and main shaft 2, ensure that bird-caging scraper 3, rhombus scraper 4 and turbine 5 and main shaft rotate simultaneously.
When going into the well, the upper end of waterpower driven rotary scraping drifting device is connected to the lower end of weighted lever or oscillator by rotating top connection, transfer to injection well downhole flow regulator by steel wire, rotated by the inner sluicing worm gear of tubing string, drive rhombus scraper and lantern scraper to rotate with main shaft further.In practical application, injection well downhole flow regulator internal diameter 46mm, rhombus scraper external diameter 44mm, and lantern scraper maximum outside diameter is 45mm, by the first scraping of rhombus scraper, and the dark scraping of the secondary of lantern scraper, thoroughly remove the dirt in injection well downhole flow regulator.And lantern scraper adopts spring steel to make, if be hampered, certain elastic deformation can occur, by the concussion of oscillator, can unfreezing smoothly.This waterpower driven rotary scraping drifting device effectively can remove the dirt in eccentric injection mandrel passage, improves efficiency of construction, reduces cost of production.
