Abstract
The utility model discloses a spew-rescue for the oil well in the petroleum industry applied to stop the spew of the well liquid in the well during the operation procedure, which is composed of a rotation valve for the oil pipe arranged within the fixing organ. Because the fixing organ in the rotation valve for the oil pipe which can be arranged in advance, when needed, the utility model can be timely and easily connected with the lift sub of the oil pipe on the wellhead, and being fastened with the hoop of the oil pipe, the utility model can be rapidly tighten the rotation valve of the oil pipe to the terminal of the oil pipe, which can validly stop the blowout of the oil pipe and rescue the blowout timely and avoid the loss of the original oil and loss of life and personal injury with a high safety.
Description
Technical field
The utility model belongs to the workover treatment equipment of petroleum industry, and particularly a kind of oil-water well blowout control device prevents well liquid to gush when being used for oil, well workover operation construction.
Background technology
The oil of petroleum industry, well are when workover treatment, the producing well that particularly has is when workover treatment, borehole pressure raises suddenly sometimes, have little time to install control head, borehole fluid just begins to be sprayed onto ground, as untimely installing wellhead control device, gas blowout accident will take place, cause great life and property loss.The oil pipe plug valve is the blowout hookup of using always, when tubing string is gushed, well head oil pipe plug valve is installed in time, and is very necessary.But because oil pipe is in case gush, well head pressure is bigger, and with crude oil and natural gas, can not dynamic device start near the well head, and the oil pipe plug valve is installed can only pure manual work, the accident in case the generation well head catches fire etc.The on-the-spot artificial oil pipe plug valve of installing owing to there not being fixed mechanism, exists very big difficulty and danger, can not in time control well head.Do not satisfy and rob the needs that spray is installed fast, occur gas blowout accident easily, cause the economic loss that to estimate.
Summary of the invention
The purpose of this utility model provides a kind of oil-water well blowout control device, utilizes existing oil pipe plug valve, can rapidly, easily the oil pipe plug valve be installed on the well head tubing string when blowout occurring or the blowout sign is arranged and prevent blowout.Avoid the crude stream environment pollution of becoming estranged, avoid casualties, improve the safety of operation field, reduce economic loss and protection environment.
The present technique solution can reach above-mentioned purpose: a kind of oil-water well blowout control device comprises the oil pipe plug valve, and the oil pipe plug valve is installed in the fixed mechanism.
The utility model compared with prior art, and is easy for installation, rob spray rapidly.Because the oil pipe plug valve has had fixed mechanism, can be fixedly mounted in the fixed mechanism in advance.Can be connected in time, easily on the pipe elevator of well head when needing, dock with tubing coupling fixing after, promptly the oil pipe plug valve is tightened on the oil pipe port.Effectively prevent tubing string blowout out of control, avoid the crude stream personal injury accident of becoming estranged, safe, have remarkable economic efficiency and social benefit.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, a kind of oil-water well blowout control device comprises oil pipe plug valve 1, and oil pipe plug valve 1 is installed in the fixed mechanism.Fixed mechanism comprises setscrew nut 2, connecting rod 3, box cupling supporting positive cover 4 and connector 5, and setscrew nut 2 and box cupling supporting positive cover 4 are connected and fixed by connecting rod 3, can use bolt, nut to be connected and fixed, and hitches connector 5 in the outer end of box cupling supporting positive cover 4 both wings.Setscrew nut 2 is the nuts that have both wings, the top threaded engagement of its internal thread and oil pipe plug valve 1.Box cupling supporting positive cover 4 is the sleeves that have both wings, and its sleeve diameter conforms to tubing coupling 6.Wrench 8 is installed in the upper end of oil pipe plug valve 1, and its underpart cylindrical is equipped with retaining spray cover 9, to block the crude oil that sprays in the oil pipe.When blowout appears in tubing string oily, the water well in operation, when needing the utility model is installed, the tubing coupling 6 that box cupling supporting positive cover 4 is aimed at well head is inserted in, and connector 5 is placed in pipe elevator 7 hangers and box cupling is set upright on ring set 4 both wings, and the utility model and well head facility are combined as a whole.Connector 5 can be by bolted two rings, adjusts spacing with bolt.Also can be the monocycle that has screw bolt and nut, bolt is set on the both wings of box cupling supporting positive cover 4, monocycle hangs on the hanger of pipe elevator 7, adjusts spacing with nut.Oil pipe plug valve 1 of the present utility model is installed in the setscrew nut 2 in advance, at this moment, as long as rotary spanner 8 can be realized the 1 whole precession downwards of oil pipe plug valve, docks with tubing coupling 6.Oil pipe plug valve 1 is in opening at this moment, retaining spray cover 9 prevents when make-up that high pressure liquid stream from spraying and hurts sb.'s feelings, treat oil pipe plug valve 1 fully with the sealing of tubing coupling 6 make-ups after, the use special spanner is closed oil pipe plug valve 1, realization is prevented blowout to the control of tubing string.Can remove connector 5 this moment, then connecting rod 3, spanner 8, setscrew nut 2, retaining spray cover 9 and box cupling supporting positive cover 4 removed, and looks the well head pressure situation and implement step operation down.
