Embodiment Construction

[0015] The structure and working principle of a blowout preventer ram provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, it is a structural schematic diagram of a blowout preventer ram that can be embedded in a casing to form a blowout preventer assembly provided by the present invention. Its structure includes an arc-shaped elastic sealing rubber body 2 with stoppers 1 at both ends, the sealing rubber body 2 can be fixed with the housing through the positioning pin 5 arranged on the stopper, and the elastic sealing rubber body Each of the upper and lower sides is provided with an exposed skeleton 4 composed of six fan-shaped metal plates 3 overlapped and combined with each other.

[0017] When in use, the above blowout preventer ram is fixed in the casing that can be fixed with the oil well head, and the two casings equipped with the ram correspond to enclose the drill...

Abstract

The invention belongs to the technical field of petroleum drilling support equipment, and discloses a blowout preventer ram. According to the technical scheme, the blowout preventer ram comprises a circular-arc elastic sealing rubber body with baffle plates at two ends, wherein the sealing rubber body can be fixed to a shell through positioning pins on the baffle plates; and the upper and lower sides of the elastic sealing rubber body are respectively provided with an exposed framework formed by lapping six sector metal plates. The sealing diameter of the blowout preventer ram is variable within a certain range, so that drill rods with different specifications and dimensions can be sealed by one pair of rams with diameter varying functions, the number of used rams is reduced, the operation process of replacing rams is omitted, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of supporting equipment for petroleum drilling, and in particular relates to a blowout preventer ram embedded in a shell and together with it to form a blowout preventer assembly. Background technique [0002] During oil field workover, the drill pipe must be tightly sealed by the blowout preventer assembly to prevent blowout, which is an important equipment used on oil wells. The structure of the blowout preventer assembly includes two shells that can be fixed to the wellhead, and the blowout preventer rams that hold the drill pipe tightly are respectively embedded and fixed in the shells in an arc structure. The structure of the currently used blowout preventer ram is composed of an arc-shaped elastic sealing rubber plate and an arc-shaped skeleton steel plate ring bonded to its two sides. Due to the fixed shape and diameter of the skeleton steel plate ring of the BOP ram of this structure, a BOP ram can ...
