Description

Technical Field

[0001] The present application relates to the technical field of oil nozzle sleeves, and more specifically, to an oil nozzle sleeve structure. Background Art

[0002] In the process of oil and gas extraction, the Christmas tree is an important well control equipment. The fixed throttle is used to install the nozzle sleeve. The nozzle sleeve can be installed with nozzles of different specifications according to the required pressure. When using the nozzle, it is necessary to replace it in order from small to large according to the formation pressure. At the beginning, the formation pressure is high, so a small nozzle is installed. After the pressure drops, it is replaced with a larger nozzle. After a period of spraying, the pressure drops again and a larger nozzle is replaced again.

[0003] According to the search, a Chinese patent with publication number CN219587545U discloses a nozzle sleeve for high-pressure oil and gas wells, which includes a main body, a nozzle sleeve channel is provided on the main body, a section at the upper end of the nozzle sleeve channel is a nozzle accommodating channel, a contraction channel is arranged below the nozzle accommodating channel, so that an inner support step is formed at the intersection of the two, an expansion channel is arranged above the nozzle accommodating channel, a plurality of first internal threads are arranged on the inner side wall of the expansion channel, and a cylindrical clamping piece is also included, a plurality of first external threads are arranged on the outer side wall of the clamping piece, a through hole penetrating the upper and lower surfaces of the clamping piece is arranged at the center position, the inner diameter of the through hole is smaller than the inner diameter of the nozzle accommodating channel and larger than the aperture of the nozzle, a section of the main body along its length direction is a cylindrical section, a plurality of second external threads are arranged on the outer side wall of the cylindrical section, which are used to match the second internal thread in the fixed throttle of the oil and gas production tree, and the nozzle sleeve can firmly fix the nozzle in the nozzle sleeve regardless of whether the oil and gas flow passes through the nozzle in the forward or reverse direction.

[0004] With respect to the above-mentioned related technologies, the applicant believes that the entire nozzle sleeve is an integrally formed structure, and no corresponding structure is provided to block it, which makes it inconvenient for the user to control the timing of oil discharge. Therefore, we propose an oil nozzle sleeve structure. Utility Model Content
