Description
Technical field
The utility model relates to a kind of oil production equipment auxiliary accessories technical field, the particularly adjustable blowout oil nozzle of a kind of heavy oil wells.
Background technology
Viscous crude refers to proportion greater than 0.9340, and ground viscosity is greater than the crude oil of 100mP.s, and because viscosity of thickened oil is large, therefore, the viscous crude field exploitation is different from the thin oil oil field development.Heavy oil wells production generally will be passed through steam injection, stewing well, open flow, turn and take out four-stage.Mainly utilize that the expansion energy of oil reservoir and crude oil sprays crude oil outside well after steam injection the open flow stage, the scene utilizes positive choke controlled pressure (prevent excessive the causing of producing pressure differential from shaking out), the oil nozzle that generally will pass through 3mm, 6mm, 9mm Three Estate is open flow successively, each grade oil nozzle open flow must pass through refluence journey-emptying-tear open oil nozzle-charge of oil mouth-refluence journey-steps such as production, complex operation, especially the part valve is because of corrosion, the switch difficulty, directly have influence on the mounting or dismounting of oil nozzle, thereby it is time-consuming to require great effort, and has had a strong impact on the efficient that extraction is produced.
The utility model content
The purpose of this utility model is to provide a kind of simple to operate, adjustable blowout oil nozzle of heavy oil wells that the journey that do not flow backwards just can be convenient for changing oil nozzle.
realize that the technical scheme that the purpose of this utility model is taked is: this oil nozzle comprises the oil nozzle overcoat, nozzle component, plug and sealing shroud, wherein, one side of oil nozzle overcoat is provided with spout, nozzle component is positioned at the oil nozzle overcoat, by the turn bar, adjusting rod and threaded rod form, adjusting rod and threaded rod are structure as a whole, be provided with the gear platform both, the end that adjusting rod stretches out the oil nozzle overcoat is provided with the moment of torsion hole, the turn bar is housed in the hole, plug is arranged on an end of oil nozzle overcoat, its excircle is connected with the oil nozzle overcoat by gas thread, endoporus and the load of adjusting rod engage sleeves connect, sealing shroud is arranged in the endoporus of the oil nozzle overcoat other end, be structure as a whole with the oil nozzle overcoat, sealing shroud is connected with threaded rod by internal thread.
The excircle of described threaded rod is provided with the external screw thread that is connected with sealing shroud, and inside is provided with blind hole, and threaded rod is provided with the oil outlet of three different pore sizes, and three oil outlets communicate with blind hole.
Described plug is a tapered cylinder, and the outside of tapered cylinder bigger diameter end is provided with outer six sides that coordinate with dismantling device.
According to the adjustable blowout oil nozzle of heavy oil wells that such scheme is made, can realize that simple to operate, the journey that do not flow backwards just can be convenient for changing the function of oil nozzle, wasted time and energy thereby solved when oil nozzle is changed in the past, affect the phenomenon of extraction production efficiency.This oil nozzle structure is reasonable in design, and is easy to use, dependable performance, and operation labour intensity is low, without dangerous.
