Abstract
The utility model provides a combined type blowout preventer with a locking function. The combined type blowout preventer with the locking function comprises a body, a slips assembly, a half sealing type flashboard assembly A, a half sealing type flashboard assembly B and a whole sealing type flashboard assembly, wherein the slips assembly, the half sealing type flashboard assembly A, the half sealing type flashboard assembly B and the whole sealing type flashboard assembly are sequentially arranged at two sides of a main channel of the body from top to bottom. The flashboards of the half sealing type flashboard assembly A and the half sealing type flashboard assembly B are respectively a 21/2 inch half sealing type flashboard and a 3 inch half sealing type flashboard. The combined type blowout preventer with the locking function is reasonable in structure, and effectively reduces the weight and height of a well control device by integrating slips, a half sealing type flashboard blowout preventer and a whole sealing type flashboard blowout preventer, thereby being convenient to assemble and disassemble and operate, and enhancing the safe reliability of work.
Description
Technical field
The utility model belongs to the petroleum machinery technical field, particularly relates to a kind of combined type preventer with locking function.
Background technology
The Operating Pressure technology is in not kill-job, not under the condition of open flow, guarantees that raising and decentralizing of oil pipe is able to safety and carries out smoothly, and it has been subject to showing great attention to of domestic and international oil and gas production enterprises with the outstanding performance of energy-conserving and environment-protective aspect.For guaranteeing carrying out smoothly of Operating Pressure, must be equipped with and contain a plurality of preventers, the well head fixing seal device of slips, can existing half-closed type preventer, full-enclosed type preventer and slips mostly are separately designs, in use need single stack, so just so that whole well control device weight is too heavy, highly too high, simultaneously also so that fluid pressure line relatively increase, lengthen, not only be not easy to loading and unloading, operation, and increased operating personnel's escape distance, and when borehole pressure is unusual, cause preventer response action to postpone, the major accidents such as blowout easily occur, security reliability is relatively poor.
The utility model content
For overcoming the deficiencies in the prior art part, the utility model provides a kind of combined type preventer with locking function of rational in infrastructure, lightweight, highly low, convenient operation.
The scheme that the utility model solves this technical problem is: comprise body, slips assembly, half-closed type flashboard assembly A, half-closed type flashboard assembly B and full-enclosed type flashboard assembly, slips assembly, half-closed type flashboard assembly A, half-closed type flashboard assembly B and full-enclosed type flashboard assembly from top to bottom in turn are housed in both sides, body main channel.
The flashboard of above-mentioned half-closed type flashboard assembly A and half-closed type flashboard assembly B is respectively 2
1/
2Inch partly seals flashboard and 3 inch partly seal flashboard.
The beneficial effects of the utility model are: it is rational in infrastructure, with slips, half-closed type ram preventer, full-enclosed type ram preventer organically in conjunction with as a whole, effectively reduce weight and the height of well control device, be convenient to loading and unloading and operation, improved safe and reliable property.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is that body, 2 is that slips assembly, 3 is that half-closed type flashboard assembly A, 4 is that half-closed type flashboard assembly B, 5 is full-enclosed type flashboard assembly.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Combined type preventer with locking function described in the utility model comprises body 1, slips assembly 2, half-closed type flashboard assembly A3, half-closed type flashboard assembly B4 and full-enclosed type flashboard assembly 5.In both sides, body 1 main channel slips assembly 2, half-closed type flashboard assembly A3, half-closed type flashboard assembly B4 and full-enclosed type flashboard assembly 5 are housed in turn from top to bottom.The flashboard of above-mentioned half-closed type flashboard assembly A3 is 2
1/
2Inch partly seals flashboard (perhaps being that 3 inch partly seal flashboard), and the flashboard of half-closed type flashboard assembly B4 is that partly to seal flashboard (perhaps be 2 to 3 inch
1/
2Inch partly seals flashboard).
Claims (2)
