Abstract

The utility model relates to packing equipment for an oil field, in particular to a high-pressure sealing rubber barrel assembly, which comprises a rubber barrel which is sleeved on a central tube of a packer, wherein a rubber barrel fixing ring is fixedly arranged on the upper part of the rubber barrel; and the upper part of the rubber barrel fixing ring is connected with a steel body connecting component. The high-pressure sealing rubber barrel assembly is characterized in that the shoulder part of the rubber barrel is circumferentially provided with a plurality of open rubber barrel isolating rings; the upper ends of the open rubber barrel isolating rings are bent outwards to form grooves; and the grooves are hinged with the lower part of the rubber barrel fixing ring. The high-pressure sealing rubber barrel assembly has a simple structure; the rubber barrel is driven by a packer power component to produce radial expansion; the split expansion open rubber barrel isolating rings are driven to swing along with deformation of the rubber barrel by taking a flange of the rubber barrel fixing ring as an axis; the lower parts of the split expansion open rubber barrel isolating rings are forced to form an expanded state along with deformation of the rubber barrel to be attached to the inner wall of a bushing; a rigid umbrella-shaped protective housing is formed on the upper part of the rubber barrel, so that the bearing capacity of the rubber barrel is effectively improved; and in addition, because of rational material selection of the rubber barrel, the rubber barrel can be used under environments of high temperature, high pressure and strong corrosion.

Description

High pressure sealing packing element assembly
Technical field
The utility model relates to the oil field and uses packing equipment, relates in particular to a kind of high pressure sealing packing element assembly.
Background technology
In the oil-gas field development field; Packer is to implement the important components and parts that oil production by layer, seperated layer water injection, separate stratum fracfturing, acidifying or machinery block down-hole injection-production technologies such as blocking up; Compression packer is use always in the packer a kind of; The rubber-like sealing drum is the core component of compression packer, and it will directly have influence on the work quality of packer.Existing sealing drum generally is the packing element of being processed by rubber, makes its distortion form the sealing to oil gas well outer tube and inner core (axle or manage) through two ends extruding, but pressure is when excessive, and the decrement that packing element receives is bigger, very easily makes its damage.In the exploitation of oil gas field; The mining depth of oil gas well is more and more darker; Along with the increase of oil gas depth, temperature, the pressure of exploitation working environment are big more, therefore; The requirements at the higher level of above-mentioned bad working environments just the packing element of packer have been proposed to adapt to, that is: the bearing capacity of seal member, heat-resisting ability and corrosion resistance etc.For improving the bearing capacity of packing element; The packing element that band metal shoulder is protected has appearred; But because the restriction of material self character; Its bearing capacity, high temperature resistant and corrosion resistance is still limited especially reaches 70-105Mpa when working environment pressure, when temperature reaches 160 ℃ of left and right sides; Both at home and abroad nearly all packing element all can not satisfy instructions for use (packing element of producing like more representational Baker Co., Ltd also can only satisfy in 84Mpa, 160 ℃ of following short time of operating mode and works, can not under 100Mpa, 160 ℃ operating mode operate as normal).Chemical standard HG/T 2701-95 oil gas field is with compression (Ys) formula packing element " in requirement also oneself through not adapting to the requirement of current oil gas field deep mining far away.For making sealing drum reach above-mentioned requirements; A kind of packing element that has pressure-bearing sleeve and polytetrafluoroethylene (PTFE) outer sleeve is arranged in the prior art; Packing element is sleeved on the packer central tube, and packing element top is fixed with the packing element retainer ring, and packing element retainer ring top is used to connect the steel body link of packer; But this packing element is when bearing strain, and the tamper-proof effect of glued construction is not very desirable between packing element and the pressure-bearing sleeve.Therefore, need to explore the compression packer sealing drum that a kind of oil gas field is used, make under its pressure-bearing, high temperature resistant and the situation that corrosion resistance is stronger, also make it when pressurized, can effectively prevent the bonding disengagement between packing element and the pressure-bearing sleeve.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and a kind of high pressure sealing packing element assembly is provided, and promotes pressure-bearing, the high temperature resistant and decay resistance of packing element.
The utility model is for realizing above-mentioned purpose; Adopt following technical scheme: a kind of high pressure sealing packing element assembly, comprise the packing element that is socketed on the packer central tube, packing element top is fixed with the packing element retainer ring; Packing element retainer ring top is connected with steel body link; It is characterized in that: said packing element shoulder ring week is provided with several open packing element spacer rings, and said open packing element spacer ring upper end is outwardly-bent fluted, the lower hinge of said groove and said packing element retainer ring.
Preferably; Said packing element retainer ring stage casing inner loop week is provided with protruding eaves; The lower port of packing element retainer ring is provided with circular-arc inward flange, and the top fit of said open packing element spacer ring floats on the lower end of packing element retainer ring, and said open packing element spacer ring is formed annular by several.
Preferably, the protruding eaves on the said packing element retainer ring is threaded with packing element spacer ring stop collar on being sleeved on the packer central tube.
Preferably, said packing element spacer ring stop collar end opening is provided with the outside eaves that turns over.
Preferably, said open packing element spacer ring is inner, the end opening of packing element spacer ring stop collar scribbles rubber adhesive, with packing element vulcanization forming together.
The beneficial effect of the utility model is: the utility model is simple in structure; Packing element receives the packer power part to promote to produce radial dilatation; The open packing element spacer ring of drive split expanding is the distortion generation swing of axle center with packing element with the flange of packing element retainer ring; Force the open packing element spacer ring of split expanding bottom to form expansion state and internal surface of sleeve pipe applying, form the umbrella protective cover of a rigidity on the top of packing element, improved the packing element bearing capacity effectively with the distortion of packing element; The reasonable material of packing element in addition can make packing element at high temperature, high pressure with than using under the strong corrosive environment.
