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
The invention belongs to oil drilling corollary equipment technical field, relate in particular to a kind of ram block that embeds in the housing and constitute the preventer assembly therewith.
Background technology
During the oil field well workover, must hold drilling rod tightly sealing by the preventer assembly and take place to prevent blowout, be a kind of visual plant that uses on the oil well.The structure of this preventer assembly comprise can with fixing two housings of well head, the ram block of realizing holding tightly drilling rod is that arc structure embeds respectively and is fixed in the housing.The structure of present employed ram block is made of with the circular arc skeleton steel plate ring that is bonded in its both sides the elastic packing rubber tile of circular arc.The ram block of this structure is because shape and the diameter of its skeleton steel plate ring are certain, and therefore a kind of ram block is merely able to be used in a kind of drilling rod of diameter; And the used drilling rod of oil well is the drilling rod combination of different-diameter, therefore must be equipped with corresponding ram block when drilling rod is changed in drilling well.The replacing of this ram block constantly not only exists the many occupied grounds of accessory, and is having a strong impact on operating efficiency.
Summary of the invention
Purpose of the present invention just provides and a kind ofly can be used in the ram block that many specifications drilling rod is held sealing tightly by reducing.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of ram block, its structure comprise two ends be provided with block, and can with the elastic packing rubber bodies of the fixing circular arc of housing, respectively be provided with by the fan-shaped metal sheet of at least two lobes in the upper and lower side of described elastic packing rubber bodies and overlap the skeleton that exposes that constitutes mutually.
Its additional technical feature also comprises:
---the elastic packing rubber bodies of described circular arc is semicircle camber structure;
---the block at described caulking gum body two ends be provided with can with the fixing alignment pin of described housing;
---the faying surface between described fan-shaped metal sheet is the fan-shaped plan structure mutually;
---the bottom that constitutes the fan-shaped faying surface of described fan-shaped metal sheet is provided with sliding block;
---the both sides that constitute described arc-shaped elastic caulking gum body two ends block are provided with fixation steel plate.
A kind of ram block provided by the present invention compared with prior art, have the following advantages: one, because constituting the skeleton fan-shaped metal sheet of at least two lobes of serving as reasons that exposes of this ram block overlaps mutually and constitutes, the diameter of the ram block sealing that makes can change in certain scope, realized the drilling rod of the salable different specification size of an auxiliary gate-board, can reduce the quantity of institute's configuration flashboard when therefore using, reduce the operating process of changing flashboard, improve operating efficiency; Its two owing to be provided with sliding block in the bottom that constitutes the fan-shaped faying surface of fan-shaped metal sheet, realize that its skeleton bearing surface overlaps mutually and the mutual hook in rear portion connects, make variable bore ram can arrive higher sealing load and longer application life.
Description of drawings
Fig. 1 is the structural representation of ram block provided by the invention;
Fig. 2 is the structural representation of second kind of ram block.
The specific embodiment
Be described in further details below in conjunction with structure and the operating principle of accompanying drawing to a kind of ram block provided by the invention.
As shown in Figure 1, be a kind of structural representation that can embed the ram block of formation preventer assembly in the housing provided by the invention.Its structure comprises that two ends are provided with the elastic packing rubber bodies 2 of the circular arc of block 1, sealing rubber bodies 2 can be fixed with housing by the alignment pin 5 that is arranged on the block, and respectively be provided with in the upper and lower side of this elastic packing rubber bodies by the fan-shaped metal sheet 3 of six lobes mutually overlap joint constitute expose skeleton 4.
During use, with above-mentioned ram block be fixed on can with the fixing housing of oil well mouth in, two housing correspondences that flashboard is housed are surrounded drilling rod, realize ram block the holding tightly drilling rod of two correspondences then by the distance of adjusting two corresponding housing, adjust two corresponding housing apart from process in because elastic packing rubber bodies 2 has certain telescopic resilience, the mutual faying surface 6 of the fan-shaped metal sheet 3 of six lobes is shifted to realize the variation of diameter or the radian of ram block by the changing of the relative positions, to realize the sealing of holding tightly to drilling rod.
The fan-shaped metal sheet 3 that constitutes above-mentioned ram block can be set at three lobes, pintongs or eight valve structures according to the size of diameter; Resistance when reducing the displacement of the changing of the relative positions between two fan-shaped metal sheet faying surfaces; at first fan-shaped metal sheet faying surface is the fan-shaped plan structure mutually; and be provided with the sliding block 7 of metal sheet faying surface in its bottom; connect with the mutual hook in the rear portion of realizing the metal sheet faying surface; to the protection of caulking gum body, make variable bore ram can arrive higher sealing load and application life during changing of the relative positions displacement sealing.
The both sides that constitute the block 1 at above-mentioned ram block arc-shaped elastic caulking gum body 2 two ends are provided with fixation steel plate 8 to realize the slip between ram block and the stationary housing.
Claims (6)
1. ram block, its structure comprise two ends be provided with block, and can with the elastic packing rubber bodies of the fixing circular arc of housing, it is characterized in that: respectively be provided with by the fan-shaped metal sheet of at least two lobes in the upper and lower side of described elastic packing rubber bodies and overlap the skeleton that exposes that constitutes mutually.
