Abstract
The utility model relates to an underground paraffin cutting and sand washing drifting device used in the oil field oil extraction field. The drifting device mainly solves the problems of the present paraffin cutting drifting tool that the structure is complicated and the paraffin can not be thoroughly cut. The drifting device is characterized in that an upper scraping guide column and a lower scraping guide column are meshed in a ratchet way; the meshed part is sleeved with an encapsulated cylinder; a guide column is arranged in an upper scraping guide hole; grooves are uniformly distributed in the radial direction on the outer wall of the guide column; radial penetrating guide pins are arranged in the grooves and fixed on the side wall of the upper scraping guide column; the lower scraping guide column adopts a spinal column with a large upper part and small lower part; a spiral scraping descaling edge connected with the lower scraping guide column into a whole body is arranged on the surface of the spinal column; the lower end of the lower scraping guide column is an inclined plane; and the inner holes of the lower scraping guide column and the guide column are through holes. The drifting device can effectively clean various paraffin deposits and dirt on the inner walls of underground pipe columns, and can not wear the inner walls of the pipe columns.
Description
Technical field:
The utility model relates to the used downhole tool in oil recovery field, oil field, a kind of specifically paraffin cutting sand washing drifting device.
Background technology:
Prolongation along with the oil field development time, tubing string in the various oil-water well wells is because long-time the use, booty on the down-hole string inwall, hard wax and other crystallizable mineral, stifled dirty dirt are understood cumulative, make the tubing string aperture become more and more littler, have had a strong impact on ordinary production.In order to solve this situation, generally use drifting, wax removal instrument, reduce the fouling of tubing string inwall.But because some fouling complex chemical composition, quality is hard, and drifting instrument commonly used is difficult to once clean out, even can cause damage to production because drifting tool construction complexity can cause the tubing string inner wall abrasion serious when drifting.
The utility model content:
In order to overcome the deficiency that exists in the background technology, the utility model provides a kind of paraffin cutting sand washing drifting device, and this drifting device can be removed the various wax deposition dirts of down-hole string inwall effectively, and can not produce heavy wear to the tubing string inwall.
The technical solution of the utility model is: a kind of paraffin cutting sand washing drifting device, comprise scraping guide pillar, following scraping guide pillar and encapsulation tube, and described is the Retchet gear type engagement between the scraping guide pillar up and down, and meshes position overcoat encapsulation tube; Last scraping guide hole is built-in with the guide pillar body, and the outer wall radial equipartition groove of guide pillar body, groove are built-in with radially to be worn guide pin and be fixed on the sidewall that scraping leads; Described scraping guide pillar down is up big and down small vertebra cylinder, and at the spirality scraping scale removal sword that the vertebra damaged surface is provided with and following scraping guide pillar is an one, the lower end of following scraping guide pillar is a beveled; And the endoporus of described scraping guide pillar down and guide pillar body is a through hole.
The described guide pin of wearing is a radial equipartition; Be equipped with sealing ring between described encapsulation tube and following scraping guide pillar.
The beneficial effect that the utlity model has is: this paraffin cutting sand washing drifting device has guide effect preferably because following scraping guide pillar adopts up big and down small awl column construction in the tubing string endoporus, drifting effectively can not cause heavy wear to the tubing string endoporus again; The spirality scraping scale removal sword of boring cylindrical surface simultaneously by constantly be rotated down, scraping, can wipe hard wax on the tubing string inwall and other crystallizable mineral, stifled dirty dirt etc. effectively off, and take out of in the well by the through hole of inside; Be Retchet gear type engagement up and down between the scraping guide pillar, can prevent effectively that sucker rod from releasing or threading off, after logical scraping was finished, when instrument proposed, the bottom centrum can be with well liquid from boring, and guarantees that oil pipe can not take off, and guarantees carrying out smoothly of production
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-guide pillar body among the figure, the last scraping guide pillar of 2-, 3-wears guide pin, and 4-encapsulates tube, 5-sealing ring, scraping guide pillar under the 6-, 7-scraping scale removal sword, 8-groove.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Shown in accompanying drawing 1, this paraffin cutting sand washing drifting device mainly comprises scraping guide pillar 2, following scraping guide pillar 6, encapsulation tube 4 and guide pillar body 1, described scraping guide pillar (2 up and down, 6) be the Retchet gear type engagement between, prevent that effectively sucker rod from releasing or threading off, and engagement position overcoat encapsulates tube 4 and fixes for screw thread between scraping guide pillar (2,6) up and down, and encapsulation tube 4 and 6 of following scraping guide pillars are equipped with sealing ring 5; Last scraping is led 2 hole and is built-in with guide pillar body 1, its upper end is connected with oil pipe, radial equipartition groove 8 is arranged on the outer wall of guide pillar body 1, the axial dimension of groove 8 is slightly larger than the height of ratchet, guarantee that up and down guide pillar is thrown off fully, groove 8 is built-in with and radially wears guide pin 3, radially wears guide pin 3 and is fixed on scraping simultaneously and leads on 2 the sidewall, during 1 rotation of guide pillar body, drive scraping guide pillar 2 and scraping guide pillar 6 rotations down successively by wearing guide pin 3; Described scraping guide pillar 6 down is up big and down small vertebra cylinder, makes it that guide effect preferably be arranged in tubing string; And the vertebra damaged surface is provided with spirality scraping scale removal sword 7, and scraping scale removal sword 7 is an one with following scraping guide pillar 6, can wipe hard wax and other crystallizable mineral on the tubing string inwall effectively off, block up dirty dirt etc.; The lower end of following scraping guide pillar 6 is a beveled, is used for sufficient sub-sand and bath; And the endoporus of described scraping guide pillar 6 down and guide pillar body 1 is a through hole, and discharge opeing is smooth and easy in the time of can guaranteeing ordinary production.
During the paraffin cutting sand washing, the upper end of guide pillar body 1 is connected with oil pipe, under the rotation of oil pipe drives, guide pillar body 1 drives intermeshing go up scraping guide pillar 2 and scraping guide pillar 6 rotations down successively, the following scraping guide pillar 6 of awl cylindricality moves down gradually at the tubing string endoporus, get final product drifting effectively, can not cause wearing and tearing again the tubing string endoporus; The spirality scraping scale removal sword 7 of boring cylindrical surface simultaneously by constantly be rotated down, scraping, can wipe hard wax on the tubing string inwall and other crystallizable mineral, stifled dirty dirt etc. effectively off, and take out of in the well by the through hole of inside; And be between the scraping guide pillar up and down the Retchet gear type engagement can prevent effectively that sucker rod from releasing or threading off that after logical scraping was finished, when instrument proposed, the bottom centrum can be with well liquid from boring, and guarantees that oil pipe can not take off, and guarantees carrying out smoothly of production.
