Abstract
A wax scraping device of the flowing well is used in the field of exploitation in oil field, comprising a paraffin scraper and a connecting rod. A locating ring is fixedly arranged on the middle part of the connecting rod, one end of which is connected with a connecting joint by a locating pin, with the connecting joint connected with a plumb bob, and the other end is connected with a steel wire connecting joint. The two ends of the paraffin scraper are connected with a localizing support respectively which is arranged on the connecting rod. When working, the paraffin scrape device is set apart in the oil well, and the paraffin scraper can slide through the connecting rod freely, thereby scraping the wax deposition in the oil tube, and supporting the unblocking of the oil tube and the normal production of flowing well. The utility model, each part of which is hardly and firmly connected, is easy to disassemble and to change the paraffin scraper.
Description
Technical field
The utility model relates to the employed wax scraping apparatus in oil recovery field, a kind of oil field, specifically a kind of flowing well paraffin scraper.
Background technology
During the flowing well ordinary production, owing to contain wax and colloidal bitumen in the crude oil, when oil temperature is lower than wax deposition point, wax in the crude oil will be separated out, and in the tube inner wall deposition, knot amasss into wax and colloidal bitumen, increase oil flow resistance, even can block oil flow channel, directly influence the ordinary production of oil well.Therefore, the wax removal of oil well is crucial technical measures that guarantee the waxy crude oil ordinary production.The method of wax removal adopts medicine wax removal and mechanical paraffin removal, mechanical paraffin removal at present mainly is to use the supporting plummet of figure of eight paraffin scraper, connect plummet with steel wire, deadweight is gone into the well by lubricator by plummet, the long-pending wax of figure of eight paraffin scraper scraping tube inner wall in the process of boring down, but because the wax on the tube wall is harder, the descending difficulty of figure of eight paraffin scraper, be difficult to the paraffin cutting degree of depth that reaches predetermined, must be by lifting up and down just repeatedly and can finishing, the wax removal time is long, working strength is big, the wax removal difficult quality guarantee.Described in addition plummet is to be connected with steel wire with paraffin scraper, very easily throws off to fall well.
Summary of the invention
The technical problems to be solved in the utility model be long at the prior art wax removal time, labour intensity is big, of poor quality and plummet of wax removal and paraffin scraper are flexible coupling and easily throw off to fall the deficiency of well, a kind of flowing well paraffin scraper is provided, each parts of this flowing well paraffin scraper connect all to adopt firmly and connect, it is good to have the wax removal quality, the paraffin cutting time is short, removes characteristics such as smooth in oil well.
Solve the problems of the technologies described above by the following technical solutions: a kind of flowing well paraffin scraper, comprise paraffin scraper 6, connecting rod 4, its structural feature is, the centre of connecting rod 4 is fixed with locating ring 7, connecting rod 4 one ends are connected with connector 2, and this connector 2 is connected with plummet 1, and the other end of connecting rod 4 is connected with connector 9.The two ends of paraffin scraper 6 are connected with locating support 5,8 respectively, and this locating support 5,8 is socketed on the connecting rod 4.
According to technique scheme, during work, by remove paraffin scraper in oil well, paraffin scraper is free to slide on connecting rod, the wax deposition material in the oil pipe can be wiped off, guarantees that the oil pipe passage is unimpeded, the flowing well ordinary production.Compared with prior art, this apparatus structure is simple, and working strength of workers is low.And, all adopt hard the connection between the each several part of the present utility model, as: connecting rod is connected with connector with plummet, the connector fastening locking of alignment pin, and this syndeton makes to be connected firmly between the parts that well does not fall.And take off alignment pin, with regard to replaceable paraffin scraper, dismounting easily.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described.
Referring to accompanying drawing 1, the utility model is by connecting rod 4, paraffin scraper 6, compositions such as connector 2,9.One end of connecting rod 4 is threaded with connector 2, and is fixing with alignment pin 3.The other end of connector 2 is threaded with plummet 1, and plummet 1 is used dowel fixes with connector 2.The other end of connecting rod 4 is threaded with connector 9.The locating ring 7 of the fixedly connected fibration together in the centre of connecting rod 4, paraffin scraper 6 one ends are connected with locating support 5, and the other end is connected with locating support 8, and locating support 5,8 is set on the connecting rod 4.
Before going into the well, the each several part screw thread is tightened, holding screw is connected firmly wax removal steel wire and paraffin scraper joint 9 at well head.Pulley, lubricator by well head are lowered into the utility model in the oil pipe, and during work, paraffin scraper 6 slides up and down at the wax deposition position of oil pipe, and the wax deposition on the tube wall is scraped broken, in the course of work, is limited the stroke of paraffin scraper 6 by locating ring 7.Wax removal is mentioned the utility model in the lubricator after finishing, and finishes wax removal work.
Technical data of the present utility model:
Paraffin scraper length: 2250mm (comprising weighted lever)
Paraffin scraper size: Φ 57.5 * 250mm
The displacement of paraffin scraper: 150mm
Paraffin scraper weight: 14.5kg
