Abstract
The utility model relates to a blowout preventer for oil well, comprising a pressure regulating apparatus and a pressure reducing apparatus. The pressure regulating apparatus comprises a pressure regulating pipe, a pressure regulating valve core and a pressure regulating spring, one end of the pressure regulating pipe is provided with an oil inlet hole and a pressure regulating hole, and an oil outlet hole is arranged on the pressure regulating pipe after the pressure regulating hole. The inner part of the pressure regulating pipe is provided with the pressure regulating valve core which can seal the pressure regulating hole, the pressure regulating spring is arranged between the pressure regulating valve core and the pressure regulating pipe, and the pressure reducing apparatus comprises a throttle type pressure reducing pipe core, a pressure reducing inlet pipe, and a pressure reducing outlet pipe. The throttle type pressure reducing pipe core is installed in the pressure reducing inlet pipe whose inner end is communicated with the pressure reducing inlet pipe after reducing pressure, and the inlet hole of the pressure reducing inlet pipe is communicated with the oil outlet hole on the pressure regulating pipe. The structure of the utility model is reasonable and compact, and using the blowout preventer for an oil well can effectively decrease or avoid the accident of oil leakage or blowout caused by abnormally excess pressure of oil pressure of output oil of the oil well in the oil field.
Description
One, technical field:
The utility model relates to the device of the oil pipeline input of the unusual superpressure oil of prevention oilfield outside well, is a kind of oil well preventer.
Two, background technology:
At present, when unusual superpressure appears in the oil pressure of the output oil of oilfield, in the oil pipeline that will the direct input well of super high pressure oil is outer, thereby make oil pipeline superpressure occur, so just may cause oil pipeline to break and leakage of oil, even cause the oil pipeline explosion and blowout takes place.
Three, summary of the invention:
The utility model provides a kind of oil well preventer, and it efficiently solves the problem of above-mentioned existence, its reasonable and compact in structure.
The technical solution of the utility model realizes by following measure: a kind of oil well preventer, it comprises regulator and decompressor, this regulator comprises surge pipe, adjusting pressuring valve core and pressure spring, one end of surge pipe has oil-in and pressure modulating opening, on the surge pipe after pressure modulating opening oil-out is arranged, adjusting pressuring valve core is installed in surge pipe and can seals pressure modulating opening, between adjusting pressuring valve core and surge pipe, pressure spring is installed, this decompressor comprises throttle type decompression tube core, decompression input pipe and decompression efferent duct, throttle type decompression tube core is installed in the decompression input pipe, the inner and the post-decompression decompression input pipe of decompression efferent duct are connected, and the input port of decompression input pipe and the oil-out on the surge pipe are connected.
Be optimization below to technique scheme:
Above-mentioned pressure spring can be installed between adjusting pressuring valve core and the spring adjusting rod, and the spring adjusting rod is installed on the surge pipe.
Above-mentioned adjusting pressuring valve core can adopt spherical or taper.
Above-mentioned throttle type decompression tube core can be installed in the decompression input pipe by screw rod.
Reasonable and compact in structure of the present utility model is utilized this oil well preventer, can effectively reduce or prevent to cause the accident of leakage of oil or blowout to take place because of the unusual superpressure of oil pressure of the output oil of oilfield.
Four, description of drawings:
Accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment,
Coding in the accompanying drawing is respectively: 1 is that A is a surge pipe, and 2 is adjusting pressuring valve core, and 3 is pressure spring, and 4 is oil-in, 5 is pressure modulating opening, and 6 is oil-out, and 7 is that B is a throttle type decompression tube core, and 8 are the decompression input pipe, 9 is that C is the decompression efferent duct, and 10 is the spring adjusting rod, and 11 is screw rod.
Five, the specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this oil well preventer comprises regulator and decompressor, this regulator comprises surge pipe 1, adjusting pressuring valve core 2 and pressure spring 3, one end of surge pipe 1 has oil-in 4 and pressure modulating opening 5, on the surge pipe 1 after pressure modulating opening 5 oil-out 6 is arranged, adjusting pressuring valve core 2 is installed in surge pipe 1 and can seals pressure modulating opening 5, between adjusting pressuring valve core 2 and surge pipe 1, pressure spring 3 is installed, this decompressor comprises throttle type decompression tube core 7, decompression input pipe 8 and decompression efferent duct 9, throttle type decompression tube core 7 is installed in the decompression input pipe 8, the inner and the post-decompression decompression input pipe 8 of decompression efferent duct 9 are connected, and the input port of decompression input pipe 8 and the oil-out 6 on the surge pipe 1 are connected.During use: the oil-in 4 of surge pipe 1 and the oil pipe of oilfield are connected, when the down-hole abnormal pressure occurs and exceeds the pressure of pressure spring 3, this adjusting pressuring valve core 2 is backed down, pressure oil enters decompression input pipe 8 from pressure modulating opening 5 and oil-out 6, enter oil pipeline through throttle type decompression tube core 7 decompression backs from the efferent duct 9 that reduces pressure, so just solved oil pipeline causes leakage of oil or blowout because of the unusual superpressure of oil pressure of the output oil of oilfield problem.
For the ease of the pressure regulated adjusting pressuring valve core 2 is the elastic force of pressure spring 3, and as shown in Figure 1, pressure spring 3 preferably is installed between adjusting pressuring valve core 2 and the spring adjusting rod 10, and spring adjusting rod 10 is installed on the surge pipe 1.
For the ease of throttle type decompression tube core 7 is installed, as shown in Figure 1, throttle type decompression tube core 7 is installed in the decompression input pipe 8 by screw rod 11.
As shown in Figure 1, adjusting pressuring valve core 2 can adopt spherical, but also can adopt the adjusting pressuring valve core of other form as required, for example: the adjusting pressuring valve core of taper.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
