Abstract
The utility model discloses a gate rubber core, which comprises a gate rubber core body (1). Side iron pads (2) are arranged on the internal side of the gate rubber core body (1), and an upper iron pad (3) and a lower iron pad are arranged on the internal upper surface and the internal lower surface of the gate rubber core body (1) respectively. The iron pads are arranged on the internal side, the internal upper surface and the internal lower surface of the gate rubber core, so that the gate rubber core is fine in bearing capacity, strength is more enhanced, the gate rubber core is not easy to break, and blowout prevention effect is better.
Description
Technical field
The utility model relates to the well control device in the drilling process, particularly a kind of flashboard glue core.
Background technology
In the oil field operation process, when drilling tool ran into high-pressure fluid (hydraulic oil, gas or water layer) in the stratum, the high-pressure fluid in the stratum will pour in the well, causes well kick or blowout phenomenon.Therefore, in drilling process, just need utilize well control device to seal well head,, guarantee the safety of operating personnel and equipment to prevent the generation of " blowout " phenomenon.Wherein, flashboard glue core is blowout prevention parts important in the well control device, when blowout takes place, can reach the purpose of blowout prevention with the sealing well head by closing flashboard glue core.But problem is that the material of flashboard glue core is generally rubber, and its pressure-bearing property is good inadequately, and intensity is also not high enough, and phenomenons such as fracture easily take place, and the well blowout preventing effect is affected.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of pressure-bearing property is good, intensity is higher, the flashboard glue core of well blowout preventing better effects if.
The technical scheme in the invention for solving the above technical problem is: a kind of flashboard glue core, comprise flashboard glue core body, the medial surface of the inner ring of described flashboard glue core body is provided with the side parallels, and the upper and lower surface of described flashboard glue core body inner ring is respectively equipped with parallels and lower padding iron.
Compared with prior art, advantage of the present utility model is: be equipped with parallels on the inner ring medial surface of this flashboard glue core and the upper and lower surface.Like this, the pressure-bearing property of this flashboard glue core is good, and intensity has also improved a lot, and difficult the fracture prevents that the effect of blowout is also better.
As preferably, described side parallels, go up parallels and lower padding iron all with described flashboard glue core body integrated injection forming.
Description of drawings
Accompanying drawing is the structural representation of the utility model flashboard glue core.
Parallels on 1 flashboard glue core body, the 2 side parallels, 3.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in drawings, a kind of flashboard glue core comprises flashboard glue core body 1, and the medial surface of the inner ring of described flashboard glue core body 1 is provided with side parallels 2, and the upper and lower surface of described flashboard glue core body inner ring is respectively equipped with parallels 3 and lower padding iron.
Described side parallels 2, go up parallels 3 and lower padding iron all with described flashboard glue core body 1 integrated injection forming.Add man-hour, side parallels 2, last parallels 3 and lower padding iron all are placed in the mould, the rubber that will plasticate then injects in the mould, by sulfuration process side parallels 2, last parallels 3 and lower padding iron and flashboard glue core body 1 is become one.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
