Description
Technical Field
The utility model relates to an oil field oil well bores and adopts technical field, especially relates to an airtight packer seal assembly.
Background
At present, along with the continuous expansion and extension in oil exploration and development field, complicated oil gas is deposited, the shared proportion of difficult use reserves is bigger and bigger, to the characteristics of low hole, hypotonic, huge thick oil reservoir, the hot gas injection technology of adopting of viscous crude of will considering to select, need to guarantee that the packer has stronger anti two-way pressure difference ability, however conventional packer seal assembly application effect is not good in high-pressure gas injection environment, seal assembly becomes the short slab, whole resistance to pressure is poor, probably there is the leakage point because of structural problem in the use.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned not enough of prior art, the utility model provides an airtight packer seal assembly solves the not good, the whole poor technical problem of resistance to pressure of current packer seal assembly sealing performance.
The utility model discloses a realize through following technical scheme:
a sealing assembly of an air-tight seal packer comprises a middle spacer ring and middle rubber cylinders respectively arranged on two sides of the middle spacer ring, wherein one end rubber cylinder is arranged on each of the outer sides of the middle rubber cylinders, one end spacer ring is further arranged between each of the middle rubber cylinders and each of the end rubber cylinders, and a back ring is arranged on each of the outer sides of the two end rubber cylinders.
Furthermore, the back ring is bowl-shaped and is made of high-strength metal materials, and the angle of the outer wall of the bowl-shaped back ring is 20-45 degrees.
Furthermore, the end rubber cylinder and the middle rubber cylinder are bowl-shaped and are made of anti-gas explosion polymer materials, and the angle between the outer walls of the bowl-shaped end rubber cylinder and the bowl-shaped middle rubber cylinder is 20-45 degrees.
Furthermore, the upper parts of the inner walls of the end rubber cylinder and the middle rubber cylinder are provided with a boss.
Furthermore, the section of the boss is semicircular.
Furthermore, the matching contact surfaces of the end spacer ring and the end rubber cylinder and the middle rubber cylinder are inclined planes; the matching contact surfaces of the middle spacer ring and the end rubber cylinder and the middle rubber cylinder are also inclined surfaces.
Furthermore, the end spacer ring and the middle spacer ring are made of high-strength and high-temperature-resistant composite materials.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model provides a pair of airtight packer seal assembly adopts unique structural design to be equipped with various anti gas blast, high strength, high temperature resistance material, can realize having stronger anti bidirectional pressure difference ability under gas environment, has better pressure-bearing nature and stability.
