Abstract
The utility model discloses a spray arrester with an auto recovery polished rod, and mainly comprises a polished rod, a pressure head, a pressure cap, a main body and a packing set; wherein, a bore which can run through the polished rod is arranged at any part of the top or bottom of the packing set; a metal ring is arranged in the bore; the inside diameter of the metal ring is slightly larger than the diameter of the polished rod and less than the inside diameters of the pressure head and pressure cap; a gap is formed between the outer circle of the metal ring and the inner circle of the bore. The utility model has the advantages that: the structure of the spray arrester has the functions of spraying guard, adjusting, polished rod recovery, non pressure relief, no packing set replacement and so on; in addition, the polish rod can be automatically recovered to guarantee the sealing and no leakage of the spray arrester, thereby, the goal of preventing the pollution to the normal production environment of the oil well can be achieved, at the same time, the crude oil can be protected from theft.
Description
Technical field
The utility model relates to the blowout prevention box of repairing polished rod in a kind of oil well automatically.
Background technology
The general pumpingh well blowout prevention box that uses is the device that connects well head sealing polished rod, mainly is made of pressure head, pressure cap, packing and main body, can only be to level and smooth polished rod seal.When burr appearred in the polished rod surface, because burr scratches packing, well head just can't seal and produce and leak outside.The normal means of chopping wound polished rod that adopt of lawless person are stolen crude oil.Prior art still can't solve this difficult problem.
Summary of the invention
The purpose of this utility model provides a kind of blowout prevention box that can repair polished rod automatically, and in order to replace existing blowout prevention box, it is not contaminated to reach assurance oil well normal production environment, solves and destroys the difficult problem that polished rod is stolen crude oil.
For achieving the above object, the technical solution of the utility model provides a kind of blowout prevention box of automatic reparation polished rod, mainly include polished rod, pressure head, pressure cap, main body and packing, the arbitrary position in wherein described packing upper part or bottom is provided with the endoporus that can pass polished rod, be provided with metal ring among the endoporus, the internal diameter of described metal ring is slightly larger than the polished rod diameter, less than the internal diameter of described pressure head, pressure cap; Gapped between the interior circle of the cylindrical of described metal ring and described endoporus.
Described metal ring can be arranged on the top or the bottom of pressure head.
Be connected with blowout preventer, device for adjusting deviation and well head connector in the bottom of described blowout prevention box.
Described packing is made by polytetrafluoroethylmaterial material.
Described well head connector is for can be threaded connector or dop or flange.
Effect of the present utility model is that the blowout prevention box of this structure has blowout prevention, tuningout, polished rod reparation, not release and changes functions such as packing, can repair polished rod automatically, guarantee blowout prevention box sealing without leakage, reach the not contaminated purpose of assurance oil well normal production environment, play the effect of antitheft crude oil simultaneously.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representations.
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the blowout prevention box of automatic reparation polished rod of the present utility model.
The blowout prevention box of automatic reparation polished rod of the present utility model, mainly include polished rod, pressure head, pressure cap, main body and packing, the arbitrary position in wherein described packing top or bottom is provided with the endoporus that can pass polished rod, be provided with metal ring 3 among the endoporus, the internal diameter of described metal ring 3 is slightly larger than polished rod 1 diameter, less than the internal diameter of described pressure head 4, pressure cap 2; Gapped between the interior circle of the cylindrical of described metal ring 3 and described endoporus.
Described metal ring 3 can be arranged on the top or the bottom of pressure head 4.
Be connected with blowout preventer 7, device for adjusting deviation 8 and well head connector 9 in turn in the bottom of described blowout prevention box.
Described packing 6 is made by polytetrafluoroethylmaterial material.
Described well head connector 9 is for can be threaded connector or dop or flange.
As shown in Figure 1, automatically repair the blowout prevention box of polished rod, mainly include polished rod, pressure head, pressure cap, main body and packing, wherein in blowout prevention box main body 5, packing 6 upper part pressure heads 4 are provided with the endoporus that can pass polished rod 1, be provided with metal ring 3 among the endoporus, the internal diameter of described metal ring 3 is slightly larger than polished rod 1 diameter, less than the internal diameter of described pressure head 4, pressure cap 2; Between the interior circle of the cylindrical of described metal ring 3 and described endoporus certain clearance is arranged.Described round metal 3 rings can radially move with described polished rod 1, can remove the burr on polished rod 1 surface at random.Circle scabbles in the burr on polished rod 1 surface during by metal ring 3 will be by metal ring 3, reaches the purpose of protection polished rod 1.Because metal ring 3 can radially move with polished rod 1, metal ring 3 can not damage polished rod 1 when normally moving.Except that this structure of Fig. 1, metal ring 3 also can be arranged on arbitrary position of pressure cap 2 tops or bottom, pressure head 4 tops or bottom, packing 6 tops or bottom.Packing 6 is made by polytetrafluoroethylmaterial material, has improved the sealing of the blowout prevention box of automatic reparation polished rod.
As shown in Figure 2, the blowout prevention box of repairing polished rod automatically also can be connected with blowout preventer 7, device for adjusting deviation 8 and well head connector 9 in the bottom of above-mentioned blowout prevention box in turn.Promptly in the lower end of the blowout prevention box main body 5 of being with the polished rod repair function, connect existing blowout preventer (rubber gate) and device for adjusting deviation successively, the well head connector can be threaded connector or dop or flange connecting elements, just constitutes the blowout prevention box with shut-in well and tuningout function.
Its operating principle is as follows:
The blowout prevention box of automatic reparation polished rod of the present utility model is passed polished rod be connected in well head, fill it up with packing, tighten pressure cap, the blowout prevention box is just sealed polished rod, and crude oil can not leak outside in the well.When burr occurring on the polished rod, the bar footpath of band burr is just greater than its latus rectum.When polished rod when the metal ring, be slightly larger than the polished rod external diameter by the internal diameter of polished rod reparation, can only allow its latus rectum partly pass through.So, burr part just can not by and scabbled, can not cause damage to packing.Guarantee blowout prevention box sealing without leakage, play the effect of antitheft crude oil simultaneously.
