Abstract
The utility model discloses a cleaning reamer in an oil pipe with scale in oil field for cleaning the inner wall of old oil pipe with scale in oil field. The cleaning reamer comprises reamers and a reamer body. The reamers are connected to a group through a spring. The front end of the reamer body is provided with a water outlet. Two groups of reamers are staggered in radial direction. The reamer body between the front water outlet of the reamer body and the reamers is also provided with a fixed guiding reamer which guides the cleaning reamer into the inner chamber of oil pipe with scale. According to the utility model, a cleaning mode of guiding the reamers into the oil pipe with scale through the fixed guiding reamer is adopted. Not only is cleaning operation for oil pipe with large-thickness scale facilitated, but also the fixed guiding reamer has a function of effectively protecting the reamers. The chips are flushed out of the pipe body through multiple chips on the reamer body. When the cleaning reamer is driven by a high-speed cleaning machine with large torque, the cleaning to the inner wall of the oil pipe can be completed through one-time reciprocating of the cleaning reamer. The operation efficiency is effectively improved.
Description
Technical field
The utility model relates to the cleaning means of oil field with old oil pipe, cleans reamer in particularly a kind of oil field fouling oil pipe, is used for the cleaning of fouling tube inner wall.
Background technology
In petroleum industry,, be the effective way that reduces production costs to utilizing again after the old oil pipe cleaning of reclaiming.But it is that each oil pipe of puzzlement oil field is repaired a great problem of producer that old oil pipe cleans always, also is the prime cost project of repairing oil pipe.How improving the oil pipe cleaning quality, reduce and clean cost, is each oil pipe reparation and relevant unit thereof the project of hammer away for a long time.For many years, domestic oil field mainly is to boil cleaning of bubble method and the cleaning of high-pressure water jet oil pipe by traditional chemistry from the old oil pipe that has greasy dirt of aboveground recovery.Clean for convenience, preliminary treatment for the fouling oil pipe is extremely important, 200610048464.5 oil passageway cleaning telescopic roll doctor and method of work, for tube inner wall cleaning telescopic roll doctor and principle thereof bigger breakthrough is being arranged aspect the oil pipe cleaning, and using in many ways, but still have the deficiency of the following aspects: 1, this scraper carries out scraping to oil pipe inside, when entering oil pipe, be difficult to realize centering, during especially to the bigger little internal diameter oil pipe of fouling thickness, can't enter in the oil pipe, consequently can't realize cleaning oil pipe; 2, the cutter block structure is single, adopts single alloy knife piece to carry out the tube inner wall scraping, and well fouling oil pipe dirt matter complexity, a kind of alloy knife is difficult to the cutting of realization to all dirty matter.
Summary of the invention
The purpose of this utility model is to clean reamer for addressing the above problem to make in a kind of oil field fouling oil pipe, improves the structure that cleans cutter, realizes that the inwall of fouling oil pipe cleans problem.
The present technique solution can reach above-mentioned purpose: clean reamer in a kind of oil field fouling oil pipe and comprise reamer and cutter hub, being connected by spring between the reamer is one group, the cutter hub front end is provided with weep hole, two groups of reamers are crisscross arranged diametrically, on the cutter hub between cutter hub front end weep hole and the reamer, fixed guiding cutter also is housed, the utility model is introduced the inner chamber of fouling oil pipe by fixed guiding cutter.
The utility model compared with prior art has following useful effect: the utility model has increased fixed guiding cutter; adopt fixed guiding cutter that reamer is introduced cleaning way in the fouling oil pipe; not only made things convenient for the cleaning of big thickness fouling oil pipe; because fixed guiding cutter has been done preliminary cleaning to the fouling tube inner wall, also has the effect of effective protection reamer again.The cutting edge of reamer adopts the alloy knife piece of two kinds of materials to be welded to form side by side, and reamer is under spring pressure, action of centrifugal force, and the cutting edge by two kinds of materials cuts the complicated dirty matter of tube inner wall, can cleaning treatment fall complicated scale forming matter.The external diameter of fixed guiding cutter on cutter hub conforms to the minimum size of internal diameter of using of cleaning oil pipe, when in the oil pipe that fixed guiding cutter is being cleaned during no drilling depth, promptly interrupt to clean, exempted do not have fixed guiding cutter cutter to scrapping the invalid cleaning that oil pipe is done.By having more the water hole body is gone out in smear metal, under the cleaning machine of high speed, high pulling torque drives, used the utility model round trip promptly can finish the cleaning of tube inner wall.Cleaning quality height, speed are fast, and operating efficiency effectively improves, and have also made contribution simultaneously to reducing cost.
Description of drawings
Fig. 1 is the front view of the utility model structural representation.
Fig. 2 is the left view of the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to Fig. 1, clean reamer in a kind of oil field fouling oil pipe, comprise reamer 3 and cutter hub 5, mounting spring 4 between the reamer 3, cutter hub 5 front ends are provided with weep hole 1, two groups of reamers 3 are crisscross arranged diametrically, on the cutter hub 5 between cutter hub 5 front end weep holes 1 and the reamer 3, fixed guiding cutter 2 are housed also.Referring to Fig. 2, fixed guiding cutter 2 is crisscross arranged diametrically with reamer 3.The external diameter of fixed guiding cutter 2 on cutter hub 5 conforms to the minimum size of internal diameter of using of cleaning oil pipe.The cutting edge of reamer 3 is welded side by side by the cutter piece of two kinds of materials, can handle complicated structural material.
Connecting thread by cutter hub 5 is connected the utility model with the rotation barral of a gun that oil pipe cleans, the moment of torsion of rotation barral of a gun is 800Nm, and rotating speed 0～400 changes adjustable.Fixed guiding cutter 2 is introduced reamer 3 oil pipe and is begun cutwork.Fixed guiding cutter 2 is finished the internal diameter size that reaming can import to reamer 3, and reamer 3 carries out cutwork, and washes to go out smear metal continuously by weep hole 1.When fixed guiding cutter 2 was hampered no drilling depth, illustrating that this oil pipe has been out of shape can not satisfy minimum instructions for use, no longer carried out inwall and cleaned next root oil pipe of promptly replaceable cleaning.
