Description

The two automatic blowout prevention blowout preventers of ball-joint tuningout of oil well
Technical field
The utility model belongs to sealing device, particularly relates to the two automatic blowout prevention blowout preventers of ball-joint tuningout of a kind of oil well.
Background technology
In the present oil field development, rod-pumped well accounts for the oil well larger proportion, too low or when strata pressure occurring and becoming situation such as big suddenly when when exploration to subsurface pressure test mud density inaccurate or that inject, oil in the well casing or gas blowout go out ground or flow into other layers in the well and take place blowout or since the suspension point track and the tubing string axis of oil pumper depart from, cause sucker rod partial wear in the oil recovery process, thereby make polished rod in pumping, the sealed packing eccentric wear is serious, seal failure, crude oil are run and are leaked and the blowout phenomenon.And wellhead assembly is main sealing, anti-inclined to one side, blowout prevention instrument.But existing wellhead assembly is because unreasonable structure, exist tuningout weak effect, packing utilization rate low, change the packing cycle short, increased labor strength, prolonged maintenance time, reduced oil recovery efficiency, increased shortcomings such as cost for oil production, therefore can not effectively improve the blowout problem.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of oil well two automatic blowout prevention blowout preventers of ball-joint tuningout, its good airproof performance, flexibly tuningout, also can prevent blowout.
The two automatic blowout prevention blowout preventers of ball-joint tuningout of oil well of the present utility model are to be made of gland, pressure cap, universal joint, packing ring and blowout prevention valve.In the upper cardan bar, have successively from bottom to up following packing ring, pressure ring, on the packing ring, gland compresses packing ring, pressure cap and compresses gland and connect with upper cardan bar spiral shell button, the upper cardan bulb is seated in the ball seat suitable for reading of tuningout joint, and upper cardan cap cutting ferrule connects on the upper cardan bulb and with the tight fit suitable for reading of tuningout joint.The lower cardan ball cup is in the end opening ball seat of tuningout joint, lower cardan cap cutting ferrule is connected on the lower cardan bulb and with the end opening tight fit of tuningout joint, lower cardan bar lower end connects blowout prevention valve, described blowout prevention valve is to be made of valve body, spray-proof ball, ball cabinet, the lower cardan bar connects with valve body, horizontal shoulder clamping mutually on valve body lower end and the oil pipe tube connector, spray-proof ball places in the cavity of valve body, the guiding awl of the valve ball that oriented axle center, the upper end of oil pipe tube connector tilts, guiding awl and valve housing body form the ball cabinet of spray-proof ball.Wherein, upper cardan the cap suitable for reading and contacted sphere of upper cardan bulb place suitable for reading and the tuningout joint all is embedded with joint ring; The end opening and the contacted sphere of the lower cardan bulb place of lower cardan cap end opening and tuningout joint all are embedded with joint ring.
As further improvement of the utility model, the ball seat of spray-proof ball is arranged in lower cardan bar lower end, the guiding awl of the valve ball that tilts to the axle center more than is arranged in the upper end of oil pipe tube connector.
As further improvement of the utility model, between a plurality of guiding awls, passage is arranged.
The two automatic blowout prevention blowout preventers of ball-joint tuningout of oil well of the present utility model, reasonable in design, easy and simple to handle, tuningout is effective, good sealing effect, packing utilization rate height, and is and easy to maintenance, cost is low, the use of blowout prevention valve has prevented blowout effectively.
Description of drawings
Fig. 1 is the structural representation of the two automatic blowout prevention blowout preventers of ball-joint tuningout of the utility model oil well;
Fig. 2 is that Figure 1A-A is to vertical view.
The specific embodiment
The two automatic blowout prevention blowout preventers of ball-joint tuningout of oil well of the present utility model, be to constitute by gland, pressure cap, universal joint, packing ring and blowout prevention valve, it is characterized in that following packing ring 2 is arranged from bottom to up successively in upper cardan bar 1, pressure ring 3, on packing ring 4, gland 5 compresses packing ring 4, pressure cap 6 and compresses gland 5 and connect with upper cardan bar 1 spiral shell button, upper cardan bulb 7 is seated in the ball seat suitable for reading of tuningout joint 8, and upper cardan cap 9 cutting ferrules connect on upper cardan bulb 7 and with the tight fit suitable for reading of tuningout joint 8; 10 of lower cardan bulbs are in the end opening ball seat of tuningout joint 8, lower cardan cap 11 cutting ferrules are connected on lower cardan bulb 10 and with the end opening tight fit of tuningout joint 8, lower cardan bar 12 lower ends connect blowout prevention valve, described blowout prevention valve is by valve body 13, spray-proof ball 14, ball cabinet 15 constitutes, lower cardan bar 12 connects with valve body 13, horizontal shoulder 17 clamping mutually on valve body 13 lower ends and the oil pipe tube connector 16, spray-proof ball 14 places in the cavity of valve body 13, there is the guiding awl 18 of the valve ball that tilts to the axle center more than the upper end of oil pipe tube connector 16, between guiding awl 18 passage 24 is arranged, guiding awl 18 and valve body 13 housings form the ball cabinet 15 of spray-proof ball 14; Wherein, upper cardan cap 9 suitable for reading and upper cardan bulb 7 contacted sphere places suitable for reading and tuningout joint 8 all are embedded with joint ring 19,20; The end opening and the lower cardan bulb 10 contacted sphere places of lower cardan cap 11 end openings and tuningout joint 8 all are embedded with joint ring 21,22.During rod broken, spray-proof ball 14 makes it be in closed state on the ball seat 23 that gets lodged in lower cardan bar 12 under the borehole pressure effect, can prevent oil spout; When sucker rod normally passed through, spray-proof ball is squeezed ran into the ball cabinet of a side, working properly the carrying out of pumping.
