Description
Technical field
The utility model relates to a kind of preventer that prevents blowout in pumpingh well well workover process, and specifically a kind of multifunctional pumping rod hangs blowout hookup, prevents blowout, prevents that the ejection of sucker rod roofbolt from causing serious accident.
Background technology
In pumpingh well workover treatment process, in the very large situation of stratum energy, as find untimely or the improper just easily generation blowout of control, present jet-preventing tool function singleness, because unreasonable structure, operation sequence be loaded down with trivial details, waste time and energy, timely and effectively blowout prevention and system spray, and following defective is specifically arranged:
During shadoof, the 250 model gate is installed on the upper flange, if well kick occurs, then seat polished rod and open flow box, front band fit sealing.If the generation blowout has little time a polished rod, then take to lose bar, lose closed-in well port strobe behind the bar.
A, installation polished rod and open flow box are relatively wasted time and energy, and polished rod is longer, and the annex on the polished rod is more, upper button difficulty.Complex operation is wasted time and energy, often owing to robbing the untimely accident that pollutes that fills.
B, take to lose the bar mode, easily the oil pipe bullet in the well is fallen, cause complicated the salvaging.
C, for the well that Φ 25mm sucker rod partial wear box cupling is arranged in the well because the diameter of Φ 25mm sucker rod partial wear box cupling is greater than the interior latus rectum of 250 model gate, bias wearing joint hoop can't pass through.
Liquid spill in the lower beam after d, the pressure testing, oil pipe, the uncontrollable flow direction causes well head mire and environment pollution, has increased unsafe factor.
Summary of the invention
The purpose of this utility model provides a kind of multifunctional pumping rod and hangs blowout hookup, overcomes the defective that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises shut-in well gate, sucker rod hanger, oil pipe short circuit, well head four-way upper flange or threeway upper flange, tubing coupling, pressure meter and diaphragm valve, it is characterized in that: the internal diameter of the oil connection of well head four-way upper flange is greater than 76mm, connect DN89mm oil pipe short circuit on the oil connection, oil pipe short circuit upper end is connected with latus rectum greater than the shut-in well gate of 89mm, be provided with a sucker rod hanger of using when preventing blowout in the upper end of oil pipe short circuit, be provided with a mozzle in the middle and lower part of oil pipe short circuit level, mozzle is provided with pressure meter and diaphragm valve.
It is large that sucker rod hanger is made as mid diameter, the multiple edge body that the upper and lower diameter is little, and the upper and lower is provided with sucker rod box thread or sucker rod male thread, and the middle part external diameter is greater than the external diameter of oil pipe short circuit.
Compared with the prior art the utility model has the following advantages:
A, simple to operate, performance safety, the system spray is rapidly.
The problem of the major diameter instrument blowout preventions such as b, solution are carried, lower bias wearing joint hoop.
C, the miscellaneous function that can reach circulation well cleanup, pressure testing device and observe the borehole pressure variation.
Lower beam plays the effect of shunting after d, the pressure testing, reduces and pollutes, and eliminates unsafe factor.

The specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises shut-in well gate 1, sucker rod hanger 2, oil pipe short circuit 4, well head four-way upper flange 5, or threeway upper flange, tubing coupling 4, pressure meter 6 and diaphragm valve 7, it is characterized in that: the internal diameter of the oil connection of well head four-way upper flange 5 is greater than 76mm, connect DN89mm oil pipe short circuit on the oil connection, oil pipe short circuit 4 upper ends are connected with latus rectum greater than the shut-in well gate 1 of 89mm, be provided with a sucker rod hanger of using when preventing blowout 2 in the upper end of oil pipe short circuit 4, be provided with a mozzle in the middle and lower part of oil pipe short circuit 4 level, mozzle is provided with pressure meter 6 and diaphragm valve 7.
When using the utility model, the utility model be installed in well head four-way lower flange above, connect with bolt and nut.Sucker rod hanger 2 is not installed first, and is for subsequent use.When in the process of pumpingh well well workover actuating oil-pumping unit, when the weight of the sucker rod roofbolt of discovery weight indicator indication lightens suddenly, this just means, and blowout will occur, should take immediately anti-spray spray measure, install sucker rod hanger 2 at the sucker rod 3 that exposes well head, install in the above again sucker rod and promote short circuit, promote sling sucker rod roofbolt in the well of short circuit with working rig by sucker rod, lay down the square clamp of card sucker rod 3, transfer gently the sucker rod roofbolt, make sucker rod hanger 2 be sitting in gently the upper end of oil pipe short circuit 4, the reversing sucker rod promotes short circuit, because sucker rod hanger 2 middle parts are that the deadweight of the in addition sucker rod roofbolt of many prismatics is when being pressed in that the reversing sucker rod promotes short circuit on the sucker rod hanger 2, sucker rod hanger 2 can not rotate, can easily promote short circuit to sucker rod and lay down proposition, shut shut-in well gate 1, finish blowout prevention work.If the pressure of pressure meter 6 indications sharply rises, should open immediately diaphragm valve 7, reduce borehole pressure, prevent the serious accident of spray bar tubing string and well head.
