Abstract
The utility model discloses a rod parting blowout preventer which comprises an upper joint body, a parting blowout-prevention sealing plate actuating mechanism and a lower joint body, wherein the upper joint body is arranged at the upper part, the parting blowout-prevention sealing plate actuating mechanism is arranged at the middle part, and the lower joint body is arranged at the lower part. The upper joint body is provided with an oil pipe internal thread and is connected with an upper oil pipe by using the oil pipe internal thread, and the lower end of the upper joint body is of a large flange structure; the lower joint body is provided with an oil pipe external thread and is connected with a lower oil pipe by using the oil pipe external thread, and the upper end of the lower joint body is of the large flange structure; the large flange of the upper joint body and the large flange of the lower joint body are hermetically connected; a rotatable sealing plate connecting plate is connected in a gap between the large flange of the upper joint body and the large flange of the lower joint body through fixed blots; the sealing plate connecting plate is fixedly provided with a parting blowout-prevention sealing plate; and a rotary torque force is provided for the sealing plate connecting plate through a torsional spring sheathed onto the fixed bolts. According to the rod parting blowout preventer disclosed by the utility model, the technical goal that wellhead oil spills and wellhead environmental pollution can be avoided because a wellhead Christmas tree is effectively plugged in time when rod parting occurs by aiming at unmanned the pumping wellhead can be achieved.
Description
Technical field
The utility model relates to oil field equipment, particularly a kind of novel rod parting blowout hookup.
Background technology
In the oil recovery activity of oil field; There is the eccentric wear problem between sucker rod and the oil pipe always; Although many devices that prevent sucker rod partial wear are arranged,, sucker rod partial wear happens occasionally owing to finally causing the accident of the well head oil leaking pollution well head environment that rod parting causes.
In traditional oil field oil recovery activity, when sucker rod partial wear finally caused rod parting, mouth of pumped oil well can not get timely sealing, caused Oil spills, well head environment pollution.
Summary of the invention
The purpose of the utility model provides a kind of rod parting blowout hookup; To solve to the unmanned mouth of pumped oil well; When rod parting, can play shutoff well head production tree timely and effectively, avoid the technical problem of well head Oil spills and well head environment pollution.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of rod parting blowout hookup comprises the top connection body on top, the disconnected lower contact body that takes off blowout prevention sealing plate actuating mechanism, bottom at middle part; Be processed with the oil pipe internal thread on the said top connection body, be used for connecting with last oil pipe, the lower end is big flange arrangement; Be processed with oil tube external thread on the lower contact body, be used for connecting with following oil pipe, the upper end is big flange arrangement; The big flange seal of said upper and lower fittings body connects; In the space between the big flange of upper and lower fittings body; Connect a rotating sealing plate gusset piece through set bolt; On the sealing plate gusset piece, being fixed with breaks takes off the blowout prevention sealing plate, through a torsionspring that is enclosed within on the hold-down screw, the torsion of rotation is provided for the sealing plate gusset piece; When sucker rod comes off from the oil pipe of upper and lower fittings body, disconnected take off blowout prevention sealing plate, sealing plate gusset piece under the effect of torsionspring when hold-down screw turns to stop position, disconnectedly take off the blowout prevention sealing plate and rotate in place in the oil pick-up tube center position.
The big flange arrangement bottom end face of top connection body lower end is processed with the sealing ring mounting groove, and this big flange bottom end face is processed with the internal thread that is used for installing torsionspring.
Said breaking takes off blowout prevention sealing plate and sucker rod contact side, is the circular shape identical with the sucker rod shape.
The utlity model has following advantage:
1. this novel rod parting blowout hookup of the utility model design to unmanned pumpingh well well head, when rod parting, can play the purpose of shutoff well head production tree timely and effectively, thereby avoid well head Oil spills and well head environment pollution.
2. fall into the shaft bottom when rod parting, the maintenance personal does not have on-call maintenance and since the shutoff quickly of rod parting blowout hookup well head, thereby effectively prevent crude oil leakage, practiced thrift the energy, protected environment pollution.
3. the utility model adopts tubing thread to connect with well head, and interchangeability is strong, and it is convenient to connect.
4. the utility model is simple in structure, and processing and manufacturing is easy, and scheme is easy to implement.
Description of drawings
Fig. 1 is the installation axis view of the utility model;
Fig. 2 is the lower contact cross-section cutaway view of the utility model;
Fig. 3 is the outline drawing of the utility model.
The specific embodiment
Specify as follows according to accompanying drawing: the utility model comprises top connection body (1), sealing ring (2), torsionspring (3), hold-down screw (4), disconnected blowout prevention sealing plate (5), sealing plate gusset piece (6), lower contact body (7) and the screw (8) etc. of taking off.Fig. 1 is a rod parting blowout hookup scheme of installation; The top connection body is processed with the oil pipe internal thread on (1); Be used for connecting with last oil pipe, the lower end is big flange arrangement, is processed with sealing ring (2) mounting groove; Be equipped with sealing ring (2) on it, big flange bottom is processed with internal thread and is used for installing torsionspring (3), hold-down screw (4), disconnected blowout prevention sealing plate (5) the sealing plate gusset piece (6) etc. that takes off; The lower contact body is processed with oil tube external thread on (7), is used for connecting with following oil pipe, and the upper end is big flange arrangement, is processed with the flange screwed hole, is used for connecting with the big flange of top connection body (1).Torsionspring (3), hold-down screw (4), disconnectedly take off blowout prevention sealing plate (5) sealing plate gusset piece (6) and all be fixed on the top connection body (1).
After sucker rod (9) gets into described rod parting blowout hookup, disconnectedly take off blowout prevention sealing plate (5) and just turn over certain angle, tightly be attached to sucker rod (9) surface.Take off into the down-hole when sucker rod (9) is disconnected; Disconnectedly take off blowout prevention sealing plate (5) sealing plate gusset piece (6) and under the effect of torsionspring (3), rotate in that sucker rod (9) is disconnected when taking off the blowout hookup place and not having sucker rod (9) around hold-down screw (4); Making and disconnected take off blowout prevention sealing plate (5) and turn to the oil pick-up tube center, thereby reaching the purpose of rod parting blowout prevention.
The key core parts of described rod parting blowout hookup are the supporting with it disconnected blowout prevention sealing plates (5) that takes off of torsionspring (3), and assembling back requires to do pressure test, and are reliable and stable with the shutoff that guarantees to turn over after the angle.
