Abstract
The invention relates to an oil-gas well pipe cleaning and well washing integral tool, which comprises a body and knife boards fixedly arranged on the body, wherein the upper end and the lower end of the body are respectively provided with an upper connecting head and a lower connecting head; the upper connecting head is provided with a screw hole; the lower connecting head is provided with external screw threads; knife board grooves in spiral distribution in the axial direction of the body and guide blocks distributed along the outer wall circumference of the body in a position near the lower connecting head are distributed on the outer wall of the body between the upper connecting head and the lower connecting head; the knife boards are embedded in the knife board grooves; and springs are arranged between the knife boards and the knife board grooves. With the adoption of the technical scheme, the oil-gas well pipe cleaning and well washing integral tool has the advantages that all of the knife boards are mutually independent; the maintenance is convenient; and the knife boards can obtain potential energy in the radial direction of the body under the effect of the springs, and extend and retract along with the inner diameter change of a pipe column, so the cleaning in the pipe column is thorough, and the operation efficiency is high.
Description
Technical field
The present invention relates to the Oil/gas Well pipe cleaning well-flushing integrated tool using in a kind of oil gas well completion operation.
Background technology
Pipe cleaning and clean-out service are the twice flow charts common in oil gas well completion operation, are all generally after pipe cleaning operation completes, to propose drilling tool to be again lowered to Flushing tubular column.Pipe cleaning and well-flushing two procedures need to complete respectively separately, and a whole set of operation is consuming time longer, and operation is numerous and diverse.Conventional tubing string cleaning method is divided into chemically cleaning and mechanical cleaning, adopts chemically cleaning often to have certain corrosiveness to down-hole string inwall, easily cause oil layer pollution, and cost is higher.And traditional mechanical cleaning often uses shell skin, iron filings, flood clod, sandy soil, paraffin, the greasy dirt of pipeline scraper to pipe string internal wall to carry out scraping cleaning, the scraping blade of pipeline scraper mostly is fixed structure, because different parts in tubing string exists the situation of different-thickness foreign material, therefore use this kind of pipeline scraper often to have clean halfway situation, easily cause that stratum is contaminated, yield reducation, have a strong impact on operating efficiency.Although the non-rotating pipeline scraper that the patent No. is 201220311767.2 preferably resolves pipe cleaning shop problem, but still there is following defect in it: 1, because the blade on unit cross section is more, make annular space area of passage lower, the foreign material under scraping easily stop up between blade, affect cleaning effect; 2, it is only suitable in pipe cleaning operation, and cannot by pipe cleaning and clean-out service is disposable completes.
Summary of the invention
The object of the invention is to propose one can once go into the well pipe cleaning and clean-out service and can complete, and easy to maintenance, to cleaning in tubing string thoroughly, avoids the Oil/gas Well pipe cleaning well-flushing integrated tool stopping up, operating efficiency is high.
The object of the present invention is achieved like this: Oil/gas Well pipe cleaning well-flushing integrated tool, comprise body and be fixed on the knife plate on body, the upper and lower two ends of body are respectively upper and lower connector, wherein upper binding head is offered screw, lower union joint is offered external screw thread, on the body outer wall between upper lower union joint, be distributed with along body shaft to spiral-distributed knife plate groove, and the guide pad of arranging along body outer wall circumference near lower union joint place, in knife plate groove, be inlaid with knife plate, between knife plate and knife plate groove, be equiped with spring.
Owing to carrying out technique scheme, the present invention can once complete pipe cleaning and clean-out service.Each knife plate in pipe cleaning step is separate, easy to maintenance, and knife plate can obtain along the potential energy of body radial direction under the effect of spring, stretches with the internal diameter varies of tubing string.In unit area, to maintain quantity few for knife plate, and annular space area of passage is large, is not easy to stop up, and in to tubing string, cleaning simultaneously thoroughly, ensures that operation carries out continuously, and operating efficiency is high.
Brief description of the drawings: technical scheme of the present invention is provided by following drawings and Examples:
Fig. 1 is Oil/gas Well pipe cleaning well-flushing integrated tool structural representation;
Fig. 2 is Oil/gas Well pipe cleaning well-flushing integrated tool knife plate fixed position structural representation.
Legend: 1, body, 2, set bolt, 3, fixed block, 4, bar holder, 5, knife plate, 6, spring, 7, guide pad.
Detailed description of the invention:
The present invention is not subject to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
Embodiment: as shown in Fig. 1-2, Oil/gas Well pipe cleaning well-flushing integrated tool comprises body 1 and is fixed on the knife plate 5 on body 1, and in body 1, offer vertically through hole, body is respectively upper and lower connector in two ends Shang Xia 1, wherein upper binding head is offered screw, and lower union joint is offered external screw thread.On body 1 outer wall between upper lower union joint, be distributed with the knife plate groove of arranging along body 1 axial screw, and the guide pad 7 of arranging along body 1 outer wall circumference near lower union joint place, in knife plate groove, be inlaid with knife plate 5.Be fixed with bar holder 4 in knife plate groove notch both sides by fixed block 3, bar holder 4 has the card rib inwardly stretching out.Knife plate 5 its external surfaces are the cutter bar blades that distribute by left-hand screw line bull, and the inner both sides of knife plate 5 are provided with the card rib of bar holder 4 thinks corresponding outward extending card rib.Between knife plate 5 and knife plate groove, be equiped with spring.
In order to ensure annular space area of passage, on the cross section of any one circumference of body 1, a knife plate 5 is only installed, knife plate 5 contains 360 ° in the projection of body 1 axial direction, Duplication is not less than 1.1, Duplication is calculated can be according to formula: (N*D)/(π * 120) calculate, wherein N is knife plate width, and D is knife plate 5 quantity.The wide 40mm of for example knife plate, on body 1, Spiral distribution has 12, and Duplication is (40*12)/(π * 120)=1.27.
When use, upper and lower connector is connected with drilling rod, along with whereabouts of the present invention, knife plate 5 scrapes foreign material on pipe string internal wall, completes pipe cleaning operation.Until body 1 fall to tubing string bottom after, by body 1 inner via hole input cleaning solution, after cleaning, solution is gushed out by circular passage between tubing string and body 1, completes clean-out service.
Above technical characterictic has formed most preferred embodiment of the present invention, and it has stronger compliance and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, meets the needs of different situations.
