Abstract
The utility model relates to a perforating operation blowout preventing device for oil extraction or well repair. The utility model comprises a shell, two sets of flashboard assemblies which are arranged in the shell in an opposite manner, four hydraulic cylinder assemblies, a control valve set, a pipeline and one pair of locking spanners. The two sets of flashboard assemblies which are arranged in the shell in an opposite manner are fixed by bolts, the two sides of the shell are respectively provided with two hydraulic cylinder assemblies which are fixed by bolts and communicated by pipelines, the ends of the hydraulic cylinder assemblies are provided with the locking spanners, a position far from a wellhead is provided with the control valve set which may connected with the device by a lead to realize a remote control. When in use on site, the device is fixed on a big cross joint by a bolt. The device solves the problems of prior art that blowouts are easy to lead to a failure in cutting off cables and that manual closing of gate is easy to result in personal injuries. The utility model may be widely applied to the oil extraction and well repair of oil fields.
Description
Technical field:
The utility model relates to the perforating job blowout hookup that the oil recovery workover treatment of a kind of oil field is used.
Background technology:
The blowout prevention problem is listed in the most important thing in the oil field oil recovery workover treatment at present, and it directly influences to recover the oil and produces and personal safety.During well workover, the blowout prevention facility mainly is to adopt the common gate of blowing out in the perforating job process, when the blowout dangerous situation occurring, use special shear to cut off the cable that the well head perforation is used, manual-lock is blown out gate then, when blowout takes place, among hasty, may cause cable to cut off, and the manual-lock gate easily cause personal injury.
The utility model content:
The utility model purpose is to provide a kind of perforating job blowout hookup, and it has solved the cable that easily causes that exists in the prior art and can't cut off when blowout takes place, and the manual-lock gate easily causes the problem of personal injury.
The technical scheme that its technical problem that solves the utility model adopts is: the perforating job blowout hookup is that a kind of hydraulic cutter formula double disc partly seals blowout hookup, this device by housing, two the cover be opposite to the flashboard assembly in the housing in opposite directions, four hydraulic cylinder assemblies, control valve group, pipeline and a pair of locking spanners are formed; The flashboard assembly that has two covers to be opposite in opposite directions in the housing in housing is screwed, being respectively equipped with two hydraulic cylinder assemblies in the both sides of housing is screwed, be communicated with pipeline between the hydraulic cylinder assembly, be provided with the locking spanner in hydraulic cylinder assembly end, can realize Long-distance Control being provided with the control valve group away from pithead position but being connected with this device lead.During on-the-spot the use this device is fixed by bolts on the big four, when unusual generation is arranged in well, control crank, the power that utilizes the hydraulic system of working rig itself to provide, hydraulic cylinder drives the bottom and partly seals flashboard, the chucking perforation is also realized preliminary sealing with the wire rope cable rapidly, promote operating grip then, hydraulic power drives blowout prevention epicoele blind rams move toward one another, because the scissors of two flashboard assemblies, at first be subjected to enough thrust in cable, cable is at first cut off, and the flashboard assembly continues move toward one another, end in contact to two blind rams, realize full shut-in well mouth, thereby effectively control the generation of blowout.
The new beneficial effect of this practicality is, this device has pressure-bearing height, characteristics such as simple, easy to operate, safe and reliable in light weight, supporting.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure, 1, housing, 2, the flashboard assembly, 3, the hydraulic cylinder assembly, 4, the control valve group, 5, pipeline, 6, the locking spanner.
The specific embodiment:
As shown in the figure, the perforating job blowout hookup by housing 1, two covers be opposite to the flashboard assembly 2 in the housing 1 in opposite directions, four hydraulic cylinder assemblies 3, control valve group 4, pipeline 5 and a pair of locking spanners 6 are formed; The flashboard assembly 3 that has two covers to be opposite in opposite directions in the housing 1 in housing 1 is screwed, being respectively equipped with hydraulic cylinder assembly 3 in the both sides of housing 1 is screwed, be communicated with pipeline 5 between the hydraulic cylinder assembly 3, be provided with locking spanner 6 in hydraulic cylinder assembly 3 ends, be connected with this device being provided with control valve group 4 usefulness leads away from pithead position; During on-the-spot the use this device is fixed by bolts on the big four, can realizes Long-distance Control.
