Abstract
The utility model provides a metal seal bridging plug of big latus rectum, is including cutting the sleeve and fixing metal seal sleeve, cone, single deck tape -recorder tile group and the soluble italic on cutting the sleeve from top to bottom in proper order. The utility model discloses no rubber part is at temperature toleration, crushing resistance and corrosion resistance all than the bridging plug is strong in the past, overall structure is compact, the part is workable, and not only the cost has been practiced thrift to the great whole length that has shortened the bridging plug, moreover control of product quality better in batch production, the latus rectum can be accomplished more than the phi 80mm above all, and after oil gas well staged fracturing, the bridging plug wholly can directly remain in the well, and big latus rectum can instead be arranged, need not to bore and mills and salvage, has reduced the well completion cost promptly, has reduced the well completion time again.
Description
Technical field
The utility model relates to bridging plug under a kind of oil well, especially a kind of metal sealing bridging plug of big orifice, belongs to bridge plug technology field under oil well.
Background technology
Along with increase day by day and the exploitation difficulty of consumption of petroleum, oil exploitation trend starts to be changed to horizontal well by Vertical Well, the pressure of underground increases along with the increase of mining depth, the sleeve of General Purpose Rubber encapsulant is more easily damaged, and along with the increase of mining depth, brill milling cost and completion time also increase thereupon.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides that a kind of entire length is short, metal sealing, big orifice can instead be arranged, without the need to boring the big orifice metal sealing bridging plug of milling and salvaging.
For achieving the above object, the technical solution adopted in the utility model is: a kind of metal sealing bridging plug of big orifice, comprises and cuts off sleeve and be fixed on the metal sealing sleeve cut off on sleeve, cone, single deck tape-recorder watt group and solvable italic from top to bottom successively.
Preferably, after down-hole sets, cut off sleeve and be drawn out outside well, non-stop layer pipe in the remaining structure of down-hole.
Preferably, described sleeve two ends of cutting off are evenly equipped with six through holes respectively.
Preferably, described metal sealing sleeve upper surface with cut off barrel contacts place and be provided with inner conical surface or Internal Spherical Surface, coordinate with solvable ball during pressure break.
Preferably, there is convex link slot described metal sealing sleeve lower surface, convex link slot and taper fit.
Preferably, there is recessed link slot described cone upper surface, and recessed link slot coordinates with metal sealing sleeve.
Preferably, described solvable italic is soluble material.
Preferably, described solvable italic there are uniform six screwed holes.
Advantage of the present utility model:
1. during solution Oil/gas Well staged fracturing, usual used bridging plug needs brill miller skill and adds the problem of cost and process time, and after realizing pressure break, bridging plug entirety can directly be retained in well, big orifice can instead be arranged, without the need to boring milling and salvaging, namely reducing completion cost, additionally reducing completion time.
2. the limitation that when solving Oil/gas Well staged fracturing, in usual used bridging plug, rubber packing material exists, adopts metallic sealing material, improves temperature tolerance, crushing resistance and corrosion resistance, be more suitable for mining environment in the future.
3. bridging plug entire length significantly shortens, and solve and transport bridging plug when going into the well curved by dog-leg, usual used bridging plug is longer, easily occurs the situation such as clamping stagnation, premature setting.The utility model compact conformation, and latus rectum can accomplish more than φ 80mm, when after Oil/gas Well staged fracturing, bridging plug entirety can directly be retained in well, and big orifice can instead be arranged, without the need to boring milling and salvaging, namely completion cost is reduced, decrease completion time, reduce the cost of manufacture of bridging plug simultaneously, and product quality can be controlled better in batch production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation before the utility model sets.
Fig. 3 is the structural representation after the utility model sets.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodiment carry out clear, intactly describe, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1: a kind of metal sealing bridging plug of big orifice, comprise and cut off sleeve 1 and be fixed on the metal sealing sleeve 2 cut off on sleeve 1, cone 3, single deck tape-recorder watt group 4 and solvable italic 5 from top to bottom successively.Described sleeve two ends of cutting off are evenly equipped with six through holes 6 respectively.Described metal sealing sleeve 2 end face with cut off barrel contacts place and be provided with the conical surface 7, coordinate with solvable ball during pressure break.There is convex link slot 8 described metal sealing sleeve 2 lower surface, and convex link slot 8 coordinates with cone 3.There is recessed link slot 10 described cone 3 upper surface, and recessed link slot 10 coordinates with metal sealing sleeve 2.Described solvable italic 5 there are uniform six screwed holes 9.
As shown in Figures 2 and 3: cut off sleeve 1 when setting and metal sealing sleeve 2 can be subject to setting force simultaneously, and direction is contrary.Cut off when sleeve 1 is subject to setting force and power can be delivered to solvable italic 5.Monodisplacement and distortion is understood when metal sealing sleeve 2 is subject to setting force, and cone 3 and single deck tape-recorder watt group 4 meeting monodisplacement thereupon.When after setting force certain time, metal sealing sleeve 2 can be deformed into the borehole wall 11 interference fit to realize sealing function, and single deck tape-recorder watt group 4 spreadings block the borehole wall 11 to realize fixing and supporting role.The pin cut off between sleeve 1 and solvable italic 5 is cut off, and cuts off sleeve 1 and is drawn out outside well, and solvable italic 5 comes off, and is dissolved in well voluntarily.
