Abstract
The utility model relates to the technical field of oil well repair, in particular to a blowout prevention oil stripper of a sucker rod, which comprises a screw plug, a union male connector, an interface, a clamp head, a connector, oil stripping rubber skin, an oil stripper body, a high-pressure blowout prevention gate and a blowout prevention connector; the screw plug and the interface, the union male connector and the interface, the interface and the oil stripper body, the clamp head and the connector, the connector and the oil stripper body, the oil stripper body and the high-pressure blowout prevention gate, and the high-pressure blowout prevention gate and the blowout prevention connector are connected by screw threads; and the oil scraping rubber skin is arranged in the oil stripper body. Due to the blowout prevention oil stripper of the sucker rod, when a well needs to be closed, the oil stripper does not need to be detached but is used together with a blowout preventer of the sucker rod to quickly and safely close the well, so that the defect that when the oil stripper of an existing sucker rod needs to be detached before the well is closed.
Description
Technical field:
The utility model relates to a kind of oil well well workover technology field, particularly a kind of sucker rod blowout prevention oil wiper.
Background technology:
In the light maintenance operation at present, the sucker rod oil wiper that uses when playing sucker rod exists many potential safety hazards and inconvenience, mainly shows:
If 1, rise when in the sucker rod process blowout omen taking place, the sucker rod oil wiper must be laid down, the sucker rod preventer is installed, there is potential safety hazard, cause blowout out of control easily.Rise in the sucker rod process,, the sucker rod preventer is installed, waste time and energy if relieve or during rest, the sucker rod oil wiper must be laid down.
2, in playing the sucker rod process, if desired during well-flushing, the sucker rod oil wiper must be laid down (sucker rod oil wiper sealing originally is poor, can not set up the well-flushing circulation), the sucker rod preventer is installed, waste time and energy.
The utility model content:
The technical problems to be solved in the utility model provides a kind of sucker rod blowout prevention oil wiper, and this oil wiper realized when the needs closing well, does not need oil wiper laid down but be used with the sucker rod preventer to carry out quick, safe closing well.Overcome the deficiency that existing sucker rod oil wiper must be laid down the sucker rod oil wiper earlier when needing closing well.
Technical solution adopted in the utility model is: a kind of sucker rod blowout prevention oil wiper, form by plug, union male joint, interface, clip head, joint, frizing rubber, body, high pressure open flow gate and open flow joint; Be screwed connection between plug and interface, union male joint and interface, interface and body, clip head and joint, joint and body, body and high pressure open flow gate, high pressure open flow gate and the open flow joint, frizing rubber is housed in the body.
The beneficial effects of the utility model are: the utility model is owing to adopted the mode that is screwed connection between plug and interface, union male joint and interface, interface and body, body and high pressure open flow gate, high pressure open flow gate and the open flow joint, thereby have when the needs closing well, do not need oil wiper laid down but be used and carry out function quick, safe closing well with the sucker rod preventer, the utility model is safe and reliable, withstand voltage 25 MPas during closing well, operation height when having reduced sucker rod increases safety.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of sucker rod blowout prevention oil wiper is made up of plug 1, union male joint 2, interface 3, clip head 4, joint 5, frizing rubber 6, body 7, high pressure open flow gate 8 and open flow joint 9; Be screwed connection between plug 1 and interface 3, union male joint 2 and interface 3, interface 3 and body 7, clip head 4 and joint 5, joint 5 and body 7, body 7 and high pressure open flow gate 8, high pressure open flow gate 8 and the open flow joint 9, frizing rubber 6 is housed in the body 7.
When the utility model is used, when playing bar, after polished rod tripped out, with sucker rod substitute from body 7 inner chambers pass with well in the sucker rod screwed connection (can be according to the box and pin of sucker rod in the well, the sucker rod substitute that selection matches), it is qualified that the clip head 4 of lower end and well head gate are connected with slips (the middle 250 model steel ring that adopts) band screw, plug 1 and interface 3 screwed connection assurances of conformity sealing during normal sucker rod, when playing the bar frizing, high pressure open flow gate 8 is opened, and the oil on the sucker rod enters sleeve pipe through high pressure open flow gate 8, open flow joint 9, connection sebific duct.Can change frizing rubber 6 according to the sucker rod of different size, it is convenient to change, and frizing is effective.
In when, in the bar process blowout omen taking place when, on the clip head 4 of upper end, connect sucker rod preventer (the middle 250 model steel ring that adopts), after the connection of slips band screw is qualified, high pressure open flow gate 8 is closed, finish closing well.Withstand voltage 25 MPas during closing well.
In playing the bar process, if desired during well-flushing, plug 1 is laid down from interface 3, oil male joint in the ninth of the ten Heavenly Stems 2 connects hose or steel hard tube line, as the pipeline outlet, connects sucker rod preventer (the middle 250 model steel ring that adopts) on the clip head 4 of upper end, after the connection of slips band screw is qualified, high pressure open flow gate 8 is closed, and flushing fluid enters from oil male joint in the ninth of the ten Heavenly Stems 2 from sleeve pipe and returns out, finishes well-flushing.Need put when pressing, high pressure open flow gate 8 is opened be got final product.
In playing the bar process, plug 1 and interface 3 screwed connection assurances of conformity sealing are when needing interim closing well, on the clip head 4 of upper end, connect sucker rod preventer (the middle 250 model steel ring that adopts), after the connection of slips band screw is qualified, high pressure open flow gate 8 is closed, finish interim closing well.Need put when pressing, high pressure open flow gate 8 is opened be got final product.
Embodiment:
Joyous 127-31-30 well, this well construction purpose is a viscous crude inspection pump (this well has vapour to scurry history), well head has been installed the utility model before playing sucker rod, when playing 35 of sucker rods, the steam ejection is arranged suddenly in the oil pipe, sucker rod preventer installing wellhead is installed immediately, and 19 seconds times spent were just sealed well head, shut-in pressure 3.5MPa.
