Abstract

The utility model relates to a descaling device for the inner wall of an oil pipe, belonging to the oil field equipment technical field. The descaling device is characterized in that a drilling and scraping part, a striking part, a drill body of a rubbing part, a front baffle and a back baffle are three-wing shaped; a front cutter body is a fixed conical scraper; a T-shaped back cutter body is arranged in a T-shaped groove and capable of radially sliding; a plate spring drives the back cutter body to radially expand out; the striking part consists of a power driving body, a movable arm, a bits shaft and a bits cotter pin; the power driving body is three-wing shaped; bits and the movable arm are sleeved on the bits shaft and in movable fit; the cotter pin limits the bits sliding axially; and the rubbing part sleeves a baffle and a brush sheet on a brush rod, and screws a brush rod pressing cap on brush rod threads to press the brush sheet. The descaling device has the advantages of compact structure, suitability for application on the scene, low energy consumption, safety, environmental protection, cleanliness and no residual on the inner wall of the oil pipe.

Description

The tube inner wall apparatus for eliminating sludge

Technical field

The utility model belongs to the oil field equipment technical field.

Background technology

Oil, well tubing are because of using for a long time in the down-hole, and overflow section diminishes after the wall fouling within it, and liquid flowing resistance increases and causes that ground water filling and pumping unit power consumption also increase thereupon.In pumpingh well because tube inner wall dirt layer can not get periodic cleaning, be subjected to sucker rod to move back and forth collision and come off to be deposited in and cause holddown on the oil well pump, influence the oil well ordinary production, the shortening pump detection period, increase the well-repairing work amount, influence oil well output and increase cost of production.The tube inner wall layer of scale is blocked up to be caused using and wasting quantity is very big.

Oil pipe has caused each oil field attention because of the waste that dirt caused, and wishes to scrap oil pipe after scale removal because of fouling, can recover to use again.

Oil pipe stain eliminating uses the jetting scale removal more at present, and this method is the high-pressure spray that adopts the 30mPa-80mPa water under high pressure to form, and the powerful tube inner wall that impacts reaches the purpose of removing tube inner wall profit dirt.The shortcoming of this method: power consumption is high, generally more than 65KW; The water that sprays usefulness can't recycle and reclaim, thereby causes the waste of water resource and the pollution of environment; Poor stability, the pressure of water under high pressure reaches more than the 30mPa, and producers' safety is constituted a threat to; Shower nozzle rotates in oil pipe and advances, and after High-Pressure Water sprayed, whether the dirt of tube inner wall is removed totally can't be checked, has the residual problem of dirt.Also have a kind of in fixing place, being placed on the fixed mount with knife bar and oil pipe, adopt the scraping of fixing straight scraper machinery, low-pressure water is towards scale removal, this quadrat method will be transported to the scale removal scene to oil pipe, increase the transport amount, the dirt that the beam hanger rail grinds in the groove can't be scraped, and not thorough this part dirt of scale removal also can cause holddown if come off.

Summary of the invention

The purpose of this utility model is:

A kind of tube inner wall apparatus for eliminating sludge of using in oil, well field is provided.

The technical solution of the utility model is:

The tube inner wall apparatus for eliminating sludge is to be formed by unit constructions such as three wing brill curettes, three wing rams, three wing wire brushes, flexible axle, motor, air compressor machines.

Brill scrape parts, impact member, brushing parts drill main body, front apron, after when plate be three wing, preceding cutter hub is fixed cone scraper, back cutter hub can radially slide for ⊥ shape is contained in the drill main body T-slot, leaf spring makes radially expansion of cutter hub afterwards;

Impact member is combined by power drive body, swing arm, gear piece axle, gear piece cottor pin, and the power drive body is three wing, and gear piece, swing arm are enclosed within on the gear piece axle and are movingly, and cottor pin restriction gear piece endwisely slips;

The brushing parts are enclosed within baffle plate, brush sheet on the brush holder support, the brushing pressure cap are screwed on the brush holder support screw thread brush sheet is compressed.

Apparatus for eliminating sludge is drawn in the tubing coupling that tiltedly is screwed in scale removal, and tracheae line outlet connection is screwed on the air inlet connections of flexible axle sheath, and flexible axle sheath gas outlet is threaded nearby with brush sheet pressure cap at flexible axle.

The beneficial effects of the utility model are:

Compact conformation, suitable The field; Low (4KW is following) consumes energy; Owing to only use compressed air to clear up, dirty slag, dirty powder under the cleaning can reclaim, and have the advantage of safety, environmental protection; Have that the cleaning tube inner wall is clean, the advantage of noresidue.

Description of drawings

Fig. 1 is the utility model tube inner wall apparatus for eliminating sludge structure chart;

Fig. 2 is the utility model three wing brill curette structure sectional views;

Fig. 3 is the utility model three wing ram structure sectional views;

Fig. 4 is the utility model three wing wire brush structure sectional views;

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1,1 is that three wing brill curettes, 2 are that three wing rams, 3 are three wing wire brushes, the 4th, flexible axle, the 5th, tracheae line, 6 motor, 7 air compressors.

Fig. 2 is 1 three wing brill curettes among Fig. 1; Work as plate, k connector in a before hexagonal screw thread, b front apron, c key, the d behind cutter hub, e carbide cutter tool, the f behind cutter hub, g drill main body, h leaf spring, l key, the j.

B, g, the k spare of three wing brill curette Fig. 2 is uniform to be three wing bodies, seam gold bullion on d, f spare, and h spare keeps radial push to f spare.C, j spare are spacing to b, k spare, and a, l spare prevent that b, k spare from axially shifting to mobile.

Fig. 3 is 2 three wing rams among Fig. 1, m swing arm, n gear piece axle o gear piece p swing arm driving body, q cottor pin.

The n spare of three wing ram Fig. 3 o spare wear bunchiness with q spare be limited to m spare between, m spare is assembled with n spare, move with q spare restrictive axial.When p spare rotating speed reached certain revolution, m spare was radially upheld, and o spare is also thereupon to radially swing.

Fig. 4 is three wing wire brushes among Fig. 1; R spare brush holder support, s spare three wing metallic brush, y spare brush baffle plate u spare brush sheet pressure cap.

2 y spares and a plurality of s spare are enclosed within on the r spare, and with the screw thread screwing force on u spare and the r spare its s spare and r spare are rotated synchronously.

The Motor Drive flexible axle rotates the back and drives with the three wing brill curettes that are threaded togather, three wing rams and three wing wire brush parts rotations.

Three wing brill curette front ends are that three its rear portions of wing fixed cone shape drill bit are expandable three wing scrapers; Three wing arms are arranged on the swing arm driving body of three wing rams, and each arm passes eyelet with power arm with axle and is connected, and uses the fixing formation of opening pin hinges, and power arm other end eyelet penetrates axle and a plurality of gear pieces are enclosed within axle and upward fixes with cottor pin; Three wing wire brushes are fixed on the brush holder support with 2 baffle plates and a brush sheet pressure cap.

During use, the wing wire brush of the wing ram of three wing brill curettes 1, three 2, three 3 is each other with being threaded, introduce oil pipes and rotate synchronously and advance by drawing oblique 4 with flexible axle 5, make tube inner wall dirty drilled, scrape, clash under brush, mill, the air-blowing integrated treatment effect, remove whole tube inner wall dirt layer, the metal surface of exposing light.
