Abstract

The utility model discloses a bidirectional anchoring hanger, which comprises a barrel-shaped main body of which the inside is sleeved with a catching rod, a hanging arm that extends or contracts under the driving of the catching rod is disposed on the main body, a pair of windows in mutual penetration are symmetrically disposed on the main body above the hanging arm, an upper hanging arm is respectively disposed in the two windows, bottom surfaces of the two windows are inclined planes which are high at the internal parts and low at the external parts, the lower end of the upper hanging arm is in contact with the inclined planes respectively, and the upper end of the upper hanging arm is respectively articulated with both sides of the catching rod.

Description

The bidirectionally anchoring hanger

Technical field

The utility model belongs to the improvement, particularly bidirectionally anchoring hanger of oilfield test with the hanger structure.

Background technology

Three grab that hanger (be symmetrically distributed in be respectively each other on the main body 120 degree) is specially adapted to inclined shaft, its advantage of horizontal well is: to designated depth release hanger is three to grab simultaneously and open (relative two grab hanger) and shortened distance of glide, has reduced depth error.Three grab three of hanger grabs to open and hangs on the oil pipe (relative two grab hanger) and can support heavier counterweight and do not glide.Three grab three of hanger grabs and can guarantee that hanger body places in the middle of the oil pipe after opening simultaneously, pounces on when being convenient to salvage to drag for device and catch hanger smoothly, has improved the success rate of salvaging instrument.But the three-jaw hanger also has with tangible limitation except its advantage is arranged.The three-jaw hanger has only solved the problem that can not fall and not have to realize upwards to slide downwards, and to some flowing wells, perhaps strict testing well is just powerless.

The utility model content

The purpose of this utility model is to provide a kind of bidirectionally anchoring hanger, and it is simple in structure, can prevent to fall under the hanger and can prevent that it from upwards sliding, and the location is reliable, and is easy to use.

The purpose of this utility model is achieved in that a kind of bidirectionally anchoring hanger, comprise that internal sleeve is equipped with the column casing shape main body of catching bar, the extension arm that is ordered about its stretching, extension or contraction by the seizure bar is being set on the main body, on the main body above the extension arm, be symmetrical arranged the window of a pair of mutual perforation, be provided with one in two windows respectively and going up the extension arm, the bottom surface of two windows is low inside and high outside inclined plane, the lower end of last extension arm contacts with said inclined plane respectively, on hang arm the upper end be hinged on respectively and catch the bar both sides.

The utility model adopts anti-sulphur stainless steel to make, and accurate positioning is not slided, and alternative steel wire test is subjected to tension strength can reach 3 tons, and the instrument that is suitable for all size connects.In application process, successively use, successfully reach 100% at the poorest well of oilfield conditions such as anteclise, Shi Xi.Prove by a large amount of uses, the utility model hanger hang arm and on hang under the synergy that arm all trails, can prevent to fall under the hanger and can prevent that it from upwards sliding, be that a kind of positioning performance is reliable, rational in infrastructure, safe testing tool easy to use, alternative steel wire test, especially be used in the high pressure flowing well, reduced economic loss, solved a great problem of oilfield test, for instrument is reliable, steady testing provides reliable guarantee, improve the test success rate, can obtain favorable economic benefit.Be one feasible, help the service aid of oilfield test, apply this testing tool and have a extensive future.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 looks cross-sectional view for master of the present utility model;

Fig. 2 is the extension arm extended state figure in the utility model.

The specific embodiment

A kind of bidirectionally anchoring hanger, as shown in Figure 1 and Figure 2, comprise that internal sleeve is equipped with the column casing shape main body 2 of catching bar 1, the extension arm 10 that is ordered about its stretching, extension or contraction by seizure bar 1 is being set on the main body 2, on the main body 2 above the extension arm 10, be symmetrical arranged the window 5 of a pair of mutual perforation, be provided with one in two windows 5 respectively and going up extension arm 4, the bottom surface of two windows 5 is low inside and high outside inclined plane 6, the lower end of last extension arm 4 contacts with said inclined plane 6 respectively, on hang arm 4 the upper end be hinged on the shoulder block 3 of catching the bar both sides respectively or directly be hinged on and catch the bar both sides.

Said extension arm 10 is two that arrange symmetrically.

Two planes that hang arm 10 places are gone up and are constituted 60 degree angles or 90 between the planes that hang arm 4 places and spend angles with two.

Hang arm 10 and on hang arm 4 free ends roller 9 be set respectively.
