Abstract
A sucker rod suspension device in the process of oil well blowout comprises a blowout preventer, a suspension device body, a sucker rod suspension connector, a big four-way valve, an oil tube in a well and a sucker rod, the blowout preventer is installed on the big four-way valve, the suspension device body is suspended on the big four-way valve and matched with the big four-way valve in a sealing mode, the lower portion of the suspension device body is connected with the oil tube in the well, internal threads are arranged on the upper portion of the suspension device body, the upper portion of the sucker rod is connected with the sucker rod suspension connector, and external threads of the sucker rod suspension connector are connected with the internal threads on the upper portion of the suspension device body. The sucker rod suspension connector is located below the blowout preventer, and the sucker rod is not located in the blowout preventer, so that a gate of the blowout preventer is rapidly closed, blowout is prevented from happening, and damage to oil and gas resources and environment pollution are avoided. The sucker rod can be fixed to the suspension device body, so that when oil well blowout is strong, the sucker rod can not play upwards to impact the blowout preventer, and the blowout preventer is prevented from being damaged.
Description
Technical field
The utility model is the wellhead equipment of the on-the-spot use of oil field pumping well workover treatment, is a kind of sucker rod hanging device for blowout of oil well.
Background technology
At present, oil well repairing operation is rising, in the process of lower sucker rod, if while there is blowout or blowout omen, because sucker rod is through the preventer on wellhead assembly and wellhead assembly, and preventer can not seal up sucker rod, therefore, in the process of actuating oil-pumping unit, control blowout and only take following two kinds of methods: the one, upside-down mounting production tree, is lowered to polished rod, rubber gate and blowout prevention box are installed, carry out kill job, eliminate blowout, the method complicated operation, labour intensity is larger, consuming time long, can not control blowout in the short period, easily miss the spray opportunity of robbing; The 2nd, in case of emergency directly sucker rod thrown away in well, close ram block, carry out kill job, eliminate blowout, there is larger potential safety hazard in the method, easily oil pipe and oil well pump is destroyed, and causes complicated salvaging accident.Chinese patent 201120399431.1 sucker rod hanging device for blowout of oil wells, while there is blowout sign in oil well, can quick closedown ram block, prevent that blowout from occurring, but can only preventing sucker rod, sucker rod hanging joint falls, can not prevent that sucker rod from moving upward, when spray gesture is larger, in well, sucker rod, by well liquid jack-up, makes sucker rod hanging joint clash into preventer, cause preventer to damage, produce heavy economic losses.
Summary of the invention
The purpose of this utility model is a kind of sucker rod hanging device for blowout of oil well of design, in actuating oil-pumping unit process, when blowout sign appears in oil well, can quick closedown ram block, prevent that blowout from occurring, and can prevent that sucker rod hanging joint from clashing into preventer, avoid preventer to damage.
The purpose of this utility model is achieved in that and comprises preventer, hanger, sucker rod hanging joint, big four, OIH pipe, sucker rod, preventer is installed on big four, hanger is suspended on big four, hanger and big four fitted seal, connecting well inner oil tube under hanger, internal thread is arranged at the top of hanger, sucker rod top is connected with sucker rod hanging joint, the external screw thread of sucker rod hanging joint is connected with the upper internal threaded of hanger, and sucker rod hanging joint is under preventer.
The beneficial effects of the utility model are: sucker rod hanging joint is under preventer, sucker rod is not in preventer, can quick closedown ram block, prevent that blowout from occurring, avoid petroleum resources destruction, environment pollution, sucker rod can be fixed on hanger, and the oil well spray gesture play that also can not make progress when larger clashes into preventer, can avoid preventer to damage.
Accompanying drawing explanation
Accompanying drawing is the utility model embodiment assembling drawing.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises preventer 1, hanger 2, sucker rod hanging joint 3, big four 4, OIH pipe 5, sucker rod 6, preventer 1 is installed on big four 4, hanger 2 is suspended on big four 4, during actual installation, hanger 2 has jackscrew to be fixed on big four 4, hanger 2 and big four 4 fitted seal, connecting well inner oil tube 5 under hanger 2, internal thread is arranged at the top of hanger 2, sucker rod 6 tops are connected with sucker rod hanging joint 3, the external screw thread of sucker rod hanging joint 3 is connected with the upper internal threaded of hanger 2, sucker rod hanging joint 3 is under preventer 1.
During normal actuating oil-pumping unit, sucker rod hanging joint 3 is not connected with sucker rod 6, when there is blowout sign in oil well, sucker rod 6 is hung on preventer 1 by rod elevator, sucker rod hanging joint 3 is connected to the top of sucker rod 6, lifting sub is connected on sucker rod hanging joint 3, mention lifting sub, take down rod elevator, transfer lifting sub, the external screw thread of sucker rod hanging joint 3 is connected with the upper internal threaded of hanger 2, back-off is taken lifting sub away, 1 li of preventer does not have object, the flashboard of preventer 1 can be closed, thereby prevent blowout.When back-off is taken lifting sub away, because sucker rod hanging joint 3 has hung sucker rod, sucker rod hanging joint 3 can not threaded off with the upper internal threaded junction of hanger 2.
Described big four 4 is on-the-spot common addresses, the planform of knowing big four 4 that all field worker personnel can be clear and definite.
