Abstract
The utility model relates to a septal-mining packer with no slip, which comprises a top joint (1) and a base joint (15); a center tube (8), a connection sleeve (13), and a cylinder sleeve (14) are fixed between the top joint (1) and the base joint (15); the center tube (8) is provided with a support sleeve (7), on which a short packer rubber (5) and a long packer rubber (6) are arranged in a line; the support sleeve is provided with a locking slips (11) and a locking sleeve (12) ensuring no springback of the short packer rubber (5) and the long packer rubber (6) after compression and is provided with an upper outburst prevention ring (3), a public outburst prevention ring (9), and a parent outburst prevention ring (10) to brace and fix the asquish packer rubbers on the casing pipe while preventing the packers from squashing and reversing; a guard ring (4) is arranged on the top joint (1) and the base joint (15) to protect the packer rubbers against scuffing while entering into the well. The utility model has the advantages of convenient operation, reliable connection, high packer setting performance, prevention of oil, acid and alkali, long service life, low cost, and good economic repayment.
Description
Technical field
The utility model relates to a kind of packer, and particularly a kind of no slips is used for the petroleum recovering field every adopting packer.
Background technology
In casing damaged well water proof oil recovery process, the packer that uses mostly is rail mounted packer and support type packer etc. at present.The packer set poor reliability of this structure, in the manufacturing process application life short, and in the deblocking process bit freezing easily, the accident rate height.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of no slips every adopting packer, and this utility model is removed packing element rigidity baffle ring by adopting many packing element combinations, reduces and goes into well rigidity part.Thereby overcome the seat envelope poor reliability that conventional packer exists, application life is short, easily the problem of bit freezing.
For this reason; the utility model provides a kind of no slips every adopting packer; wherein; comprise top connection 1 and lower contact 15; 15 of top connection 1 and lower contacts are provided with central tube 8; accept cover 13 and cylinder sleeve 14; central tube 8 is provided with support set 7; short rubber cylinder 5 and long packing element type 6 have been arranged side by side on the support set 7; support set 7 is provided with locking slips 11 and the lock sleeve 12 that is used to guarantee not resilience after short rubber cylinder 5 and long packing element type 6 compressions; support set 7 is provided with when being used to protect packing element not to be crushed counter-rotating; the packing element that flattens is supported and fixed on last protrusion-dispelling ring 3 on the sleeve pipe; public protrusion-dispelling ring 9 and female protrusion-dispelling ring 10, top connection 1 and lower contact 15 are provided with and are used for protecting packing element not hung the protection ring 4 of hindering in the process of going into well.
The multinomial combination of the utility model by short rubber cylinder 5 and long packing element type 6 solved as going into well seat envelope midway every adopting packer, solved every adopting packer to go into the well seat and seal insecure problem by last protrusion-dispelling ring 3, protection ring 4, public protrusion-dispelling ring 9 and female protrusion-dispelling ring 10.Simultaneously also solved the deblocking problem of bit freezing midway, increased to a great extent every validity of adopting tubing string and safety.Simultaneously, the utility model adopts many packing elements technology, solved the reliability that there is the situation lower packet seat envelope that heavy corrosion damages in the casing damaged well internal surface of sleeve pipe, can guarantee once seat envelope, solved in the past packer and gone into the low problem of well seat envelope success rate various corrosion and damage wells.The utility model seat seal pressure is lower than 12Mpa, and inner diameter of centerpipe is 62mm, can be used on the pump and pump under the water proof of various combination mode recover the oil.Therefore the utility model is easy to use, connect reliably, and seat sealing property height, the oil resistant acid and alkali-resistance, long service life, with low cost, benefit is obvious.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Fig. 1 is the utility model structural representation.As shown in Figure 1, the utility model comprises between top connection 1 and lower contact 15, top connection 1 and the lower contact 15 and is provided with central tube 8, accepts cover 13 and cylinder sleeve 14, central tube 8 is provided with support set 7, short rubber cylinder 5 and long packing element type 6 have been arranged side by side on the support set 7, short rubber cylinder 5 is three, and long packing element type 6 is two.Support set 7 is provided with locking slips 11 and lock sleeve 12, not resilience after locking slips 11 and lock sleeve 12 assurance short rubber cylinders 5 and long packing element type 6 compressions.Support set 7 is provided with protrusion-dispelling ring 3, public protrusion-dispelling ring 9 and female protrusion-dispelling ring 10; last protrusion-dispelling ring 3, public protrusion-dispelling ring 9 and female protrusion-dispelling ring 10 be not when the protection packing element is crushed counter-rotating; the packing element that flattens is supported and fixed on the sleeve pipe; hinder in order to protect packing element in going into the process of well, not hung simultaneously, be provided with protection ring 4.
The utility model is suppressed by pressure device short rubber cylinder 5 extruding is entered in the long packing element type 6, makes in the long packing element type 6 concave edges stick up Expansion sealing and realizes every the purpose of adopting.The utility model two ends connecting thread all can adopt the API standard thread, can easily be connected with any tubing string.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
