Abstract
The utility model discloses a compression packer rubber tube which comprises a metal framework and a fluororubber rubber tube. A main body of the metal framework is a barrel, a protrusion is formed on the peripheral surface of the main body at the position close to a port, the outer end of the protrusion bends in the direction away from the port, the inner surface of the main body, the lower surface of the protrusion and the outer surface of the main body below the protrusion are all rough surfaces, the shape of one end of the fluororubber rubber tube is matched with the shape of the metal framework, the metal framework is embedded at the end of the fluororubber rubber tube, and the rough surfaces are adhered with the fluororubber rubber tube. The compression packer rubber tube is resistant to temperature and pressure and long in constant working time, and avoids safety accidents of irregular open holes, complex well conditions and puncture leakage, drill sticking, well falling, tool fracture and the like.
Description
Technical field
The utility model relates to a kind of open hole well prospecting tools, particularly relates to a kind of packing element.
Background technology
In recent years, since the exhaustive exploitation of China's oil industry, the asymptotic exhaustion of the petroleum resources more than 6000 meters, and oil gas is surveyed and exploitation is carried out to stratum darker below 6000 meters.Must adopt packer and slips to set simultaneously with arriving the down-hole under the logging tool during well logging, carry out the detection of oil-gas Layer then.By make the rapid compression-expansion of cartridge in the outside to the packer pressurization, elasticity packing element and the borehole wall fit tightly to be realized setting when setting.In the oil gas of open hole well below 6000 meters is surveyed, increase along with well depth, the temperature and pressure of down-hole is more and more higher, because the open hole well borehole wall is irregular, therefore the seal clearance of packing element and the borehole wall is bigger when the packing element design of open hole well, the decrement of packing element is bigger, and the crowded crack of shoulder phenomenon is serious, particularly for the irregular open hole well of the borehole wall.In addition, along with well depth increases, the H of down-hole

2, complex media such as mud, crude oil, salt solution is also more and more serious to the erosion of packing element.
Existing cartridge can not adapt to the instructions for use of this operating mode, occurs the material sclerosis under HTHP, and shoulder is torn piece, longitudinal cracking, seal failure, thus cause the too early deblocking of packer, wrong envelope or scurry envelope, finally make packer can't trip out or cause other even more serious fault.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of compression type packer tubling, can effectively improve down-hole safety of construction and success rate in the deep-well environment of high temperature, high pressure, the erosion of high complex media--use down.
For this reason, the technical solution of the utility model is as follows:
A kind of compression type packer tubling, comprise metallic framework and fluorubber packing element, the main body of described metallic framework is cylindrical shell, be formed with projection at the main body outer surface near the port, the outer end of described projection is to the direction bending that deviates from port, main body external surface under the inner surface of described main body, the soffit of described projection and the described projection is rough surface, shape and the described metallic framework of described fluorubber packing element one end adapt, described metallic framework is inlaid in this end of described fluorubber packing element, and described rough surface and described fluorubber packing element are bonded together.In addition, the length of described fluorubber packing element below described metallic framework bottom is greater than the length of described metallic framework.This structure has improved the bonding strength of metallic framework and fluorubber packing element.
It is higher that projection on the metallic framework has improved this packing element shoulder load performance, effectively reduces the deflection of shoulder rubber, reduces the stress of cartridge shoulder when the limit expands and concentrate, and guarantees the reliability of compression cartridge, prolongs the application life of product.
The fluorubber packing element has intensity height, high temperature resistant, high pressure resistant and anti-H

2, down-hole complex media such as salt solution characteristics, and have better elastic, can recover rapidly during pressure release behind the rubber bodies compression seal, be convenient to envelope.
This compression type packer tubling can heatproof, withstand voltage, continuous working period is long, avoided incident thorn leakage, bit freezing under open hole well hole anomaly, hole condition complexity and high temperature, the high pressure, fallen the generation of security incidents such as well, broken tool.
Description of drawings
Fig. 1 is the generalized section of compression type packer tubling of the present utility model;
Fig. 2 is the structural representation of an embodiment of the metallic framework in the utility model.
The specific embodiment
Be elaborated below in conjunction with the structure of the drawings and specific embodiments to compression type packer tubling of the present utility model.
Referring to Fig. 1 and Fig. 2, the disclosed compression type packer tubling of the utility model comprises metallic framework 1 and fluorubber packing element 2.The main body of metallic framework 1 is cylindrical shell, be formed with projection 3 at the main body outer surface near the port, and the outer end of projection 3 is to the direction bending that deviates from port.The soffit of the inner surface of main body, projection 3 and the projection main body external surface below 3 is rough surface, so as with fluorubber packing element 2 strong bonded.Shape and the metallic framework 1 of fluorubber packing element 2 one ends adapt, and metallic framework 1 is inlaid in this end of fluorubber packing element 2, and the rough surface of metallic framework 1 and described fluorubber packing element are bonded together.The length of described fluorubber packing element 2 below metallic framework 1 bottom is greater than the length of metallic framework 1.
This compression type packer tubling has been taked metallic framework and fluorubber composite construction, earlier metallic framework is carried out blasting treatment, and brushwork adhesive forms with the sulfuration of fluorubber overall thermal then again.
Metallic framework adopts the protrusion-dispelling design, has increased projection, improves the shoulder load performance, reduce the deflection of shoulder rubber, reduce the stress concentration phenomenon of cartridge shoulder when the limit expands, guarantee the reliability that packing element sets and seals, prolonged the application life of product.
During use this packing element packed in the open hole packer, by pressurization packing element is expanded and the packing stratum.
