Abstract
The utility model relates to a blowout preventer of a sucker rod, which comprises a blowing tube 3, an upper cover 4, a rubber core 5, a shell 6 and a lower joint 7. The blowout preventer is characterized in that the inner pipe wall of a center short pipe shape opening of the upper cover 4 is provided with a paraffin scraper consisting of a wax spatula1 and a spring piece. The utility model has reasonable design, convenient processing and reliable work, and can be widely applied to the blowout prevention operation of the sucker rod for maintaining various pumping wells. Because the paraffin scraper can effectively remove high-strength dirt adhered on the outer wall of the sucker rod, the purposes for preventing the dirt from leaking and protecting the environment are achieved.
Description
Technical field:
The utility model relates to a kind of oil field underground work instrument, especially for a kind of sucker rod preventer of pumpingh well.
Technical background:
Before the utility model, each oil field is when carrying out the pumpingh well maintenance activity, down-hole liquid overflows when preventing to trip out rod string, and the liquid and the dirt contaminated environment of the adhesion of sucker rod outer wall, the general preventer that has the glue core that adopts more, come the annular space between Seal Oil roofbolt and the tubing string, and scrape off liquid and dirt that the sucker rod outer wall adheres to; But, when the dirt intensity that is adhered to when the sucker rod outer wall is higher, rely on the glue core on the preventer effectively not remove, will certainly cause it to leak and contaminated environment.
Summary of the invention:
The purpose of this utility model is: for the oil field pumping well maintenance activity provides a kind of sucker rod preventer, because this device is to have additional paraffin scraper on the basis of glue core blowout prevention, can effectively remove the high strength dirt that sticks on the sucker rod outer wall, prevent that it from leaking and cause the purpose of environment pollution thereby reached.
The purpose of this utility model realizes by following measure: a kind of sucker rod preventer, comprise blow-off pipe, loam cake, glue core, housing and lower contact, and the glue core of ring-type is installed in the shell of short tubular, the loam cake that connects lower contact, top installation dish type below it, the loam cake center is processed with the opening of a short tubular, and the blow-off pipe of a tubulose also is installed on the opening of its short tubular; It is characterized in that on the inner tubal wall of loam cake center short tubular opening, being equipped with by the wax spatula of sheet and spring leaf and the paraffin scraper that constitutes.
The purpose of this utility model can also realize by following measure: on the inner tubal wall of sucker rod preventer loam cake center short tubular opening, the paraffin scraper that constitutes by the wax spatula of sheet and spring leaf of installation, can be 2-4 uniform.
The utility model is reasonable in design, easy to process, reliable operation, can be widely used in the sucker rod preventing spraying operation of all kinds of pumpingh well maintenances.Because the paraffin scraper on the device can effectively be removed and sticks to high-intensity dirt on the sucker rod outer wall, thereby realized preventing that it from leaking and protect the purpose of environment.
Description of drawings:
Fig. 1 is the structural representation of sucker rod preventer.
The specific embodiment:
The sucker rod preventer is to be made of wax spatula 1, spring leaf 2, blow-off pipe 3, loam cake 4, glue core 5, housing 6 and lower contact 7 etc., and the glue core 5 of ring-type is installed in the shell 6 of short tubular, connects the loam cake 4 of lower contact 7, top installation dish type below it; Loam cake 4 centers are processed with the opening of a short tubular, and the blow-off pipe 3 of a tubulose also is installed on the opening of its short tubular, are equipped with on the inner tubal wall of loam cake 4 center short tubular openings by the wax spatula 1 of sheet and spring leaf 2 and the paraffin scraper that constitutes; On the inner tubal wall of loam cake 4 center short tubular openings, the paraffin scraper that constitutes by the wax spatula 1 of sheet and spring leaf 2 of installation, can be 2-4 uniform.
The operating principle and the using method of sucker rod preventer are: before all kinds of pumpingh well maintenances trip out the preventing spraying operation of sucker rod from the down-hole, by a quarter butt sucker rod preventer is sleeved on the beam hanger post earlier, and be installed on the well head by lower contact 7, because the effect of spring leaf 2, wax spatula 1 can tightly abut on the beam hanger wall, and just can carry out the trip-out operation of sucker rod this moment; Carry in the process on the beam hanger post, liquid and dirt that the sucker rod outer wall adheres to can be eliminated by glue core 5 time; Higher when the dirt intensity that the sucker rod outer wall is adhered to, only rely on glue core 5 can not full scale clearance the time, the wax spatula 1 that then can tightly be abutted on the beam hanger wall is further removed; Owing to the paraffin scraper that is made of wax spatula 1 and spring leaf 2 is that 2-4 is uniform, thereby can effectively remove the high strength dirt that the sucker rod outer wall is adhered to, realize preventing that it from leaking and protect the purpose of environment.
