Problems solved by technology

Except that CAMERON company uses hydraulic straight line to open the side door so that the structure of the left and right side doors is exactly the same and can be interchanged, the other two companies use the rotary to open the side door and cannot realize the interchange
[0004] Therefore, the technical defect existing in the prior art is: the ram blowout preventer that rotates to open the side door, and the left and right side doors cannot be used interchangeably, resulting in increased product design cycle, long machining cycle, cumbersome technical process, and many inspection items. , high cost of quality control, high inventory and other production costs

Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] see figure 1 , a side door of the blowout preventer of the present embodiment includes a side door body 30, and the side door body 30 is provided with a side door inner hole 31 and a liquid cylinder groove 32. The upper end of the side door body 30 has a hinge connection part 33, and the hinge connection parts 33 are respectively There are a first oil hole 333 and a second oil hole 334 extending from top to bottom to the cylinder groove 32. The cylinder groove 32 is provided with a first inner oil hole 337 communicating with the first oil hole 333. 32 is also provided with a first outer oil hole 335 communicating with the first oil hole 333, and a second inner oil hole 338 communicating with the second oil hole 334 is provided on the liquid cylinder groove 32. A second outer oil hole 336 communicating with the second oil hole 334 is o...

Abstract

The invention discloses blowout preventer side doors and a blowout preventer with left and right interchangeable side doors. Each blowout preventer side door comprises a side door body (30), a side door inner hole (31) and a hydraulic cylinder groove (32) are formed in each side door body (30), a hinge connecting portion (33) is arranged at the upper end of each side door body (30), a first oil hole (333) and a second oil hole (334) which extend to the corresponding hydraulic cylinder groove (32) from top to bottom are respectively formed in each hinge connecting portion (33), a first inner oil hole (337) which communicates with the corresponding first oil hole (333) is formed in each hydraulic cylinder groove (32), a first outer oil hole (335) which communicates with the corresponding first oil hole (333) is further formed in the outer side of each hydraulic cylinder groove (32), a second inner oil hole (338) which communicates with the corresponding second oil hole (334) is formed in each hydraulic cylinder groove (32), a second outer oil hole (336) which communicates with the corresponding oil hole (334) is further formed in the outer side of each hydraulic cylinder groove (32), and each first outer oil hole (335) and the corresponding second outer oil hole (336) are symmetrically distributed in the left-right direction. Gate plates of the side doors are opened rotatably, after the blowout preventer is provided with the blowout preventer side doors, the left and right side doors can be interchanged, and therefore, production cost is reduced.

Description

technical field [0001] The invention relates to a device for sealing or sealing off boreholes or wells in well drilling, in particular to a blowout preventer with interchangeable side doors and left and right side doors. Background technique [0002] The hydraulic ram blowout preventer is an important part of the well control device. According to the number of rams, it can be divided into single ram blowout preventer, double ram blowout preventer and triple ram blowout preventer; classified according to the shape of the ram , can be full-sealed ram BOP, semi-sealed ram BOP, shear-sealed ram BOP and variable-diameter ram BOP. The basic structure of the ram preventer usually includes the shell, side door, side door bolts, hydraulic cylinder, cylinder head, piston assembly, hydraulic cylinder bolts and ram. [0003] In the world, the side door structure of BOP is mainly represented by the products of American CAMERON Company, American SHAFFER Company and American HYDRIL Compan...
