Abstract
The utility model provides a sucker rod well plugging device, consisting of a control valve, a well plugging body, a sucker rod and a sucker rod seat. The control valve is arranged on the well plugging body; the sucker rod seat is transversely arranged on the well plugging body; the sucker rod sits on the sucker rod seat; the control valve and the well plugging body are in hooping connection; the sucker rod seat and the well plugging body are in threaded connection. When an oil well does not blow out, the sucker rod seat is withdrawn so as to ensure that the well plugging body is unblocked, then the oil well can normally operate, and the sucker rod smoothly passes through the well plugging body. When the oil well blows out, the sucker rod sits on the sucker rod seat; the upper end of the sucker rod is positioned under the control valve; the control valve can be completely closed to allow the oil well to be in a controllable state, so as to eliminate well blowout, guarantee safe production, allow the oil well to smoothly accomplish workover operation and raise the economic benefit of the oil well.
Description
Technical field:
The utility model is the blowout control equipment that oil well repairing operation is used, particularly a kind of sucker rod blowout preventer.
Background technology:
With the producing well of sucker rod oil pumping when the workover treatment, to in well, propose with the sucker rod G.I.H or with sucker rod, sucker rod be lowered to or the proposition process in blowout takes place sometimes, in order to control oil well when the blowout well, do not make oil well out of control, the scene is to adorn a valve at well head at present, and during blowout, sucker rod promotes the elevator seat on valve, valve-off again, but because sucker rod will pass valve, so there is the problem that is not closed completely, crude oil is injected in outside the well in a large number during blowout, basically be in runaway condition, there are serious safety problem and problem of environmental pollution, influence workman's work, waste crude oil.
Summary of the invention:
The purpose of this utility model provides a kind of sucker rod blowout preventer, when an oil well blew out, and energy tight closing oil flow channel, but make oil well be in state of a control, eliminate blowout, guarantee safety in production.
The purpose of this utility model has been achieved in that control valve, sucker rod, also be made up of shut-in well body, oil pumping pole socket, control valve is installed on the shut-in well body, and sucker rod is in the shut-in well body, the oil pumping pole socket laterally is installed on the shut-in well body, and the oil pumping pole socket is on the oil pumping pole socket.
Control valve is that clip connects with the shut-in well body.
Oil pumping pole socket and shut-in well body thread connection.
The beneficial effects of the utility model: during blowout, sucker rod is located on the oil pumping pole socket, and the sucker rod upper end is under the control valve, control valve can be closed fully, makes oil well be in controllable state, eliminates blowout, guarantee safety in production, make oil well finish workover treatment smoothly, improve the oil well economic benefit.
Description of drawings:
Accompanying drawing is an assembled view of the present utility model.
The specific embodiment:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Is made up of control valve 1, sucker rod 3, shut-in well body 2, oil pumping pole socket 4, control valve 1 is installed on the shut-in well body 2, and sucker rod 3 is in the shut-in well body 2, and oil pumping pole socket 4 laterally is installed on the shut-in well body 2, and 3 of sucker rods are on the pole socket 4 of pumping.Control valve 1 connects for clip with shut-in well body 2.Oil pumping pole socket 4 and shut-in well body 2) thread connection.
When oil well did not spray, oil pumping pole socket 4 withdrawed from, and made shut-in well body 2 unblocked, and oil well can normal operation, and sucker rod 3 is smoothly by shut-in well bodies 2.When an oil well blew out, rotation oil pumping pole socket 4 stretched in the shut-in well body 2 oil pumping pole socket 4, the width of two oil pumping between the pole socket 4 be less than the joint of sucker rod 3, and 3 of sucker rods are on oil pumping pole socket 4, and the sucker rod upper end is under the control valve, closed control valve 1 makes oil well be in controllable state.
