Abstract

The invention provides an oil nozzle sleeve and a wellhead device. The oil nozzle sleeve comprises a seat body which is provided with an oil inlet channel, a plurality of oil flow channels and a first accommodating cavity for communicating the oil inlet channel with the plurality of oil flow channels; a valve element comprises a first valve element body, the first valve element body is rotatably arranged in the first containing cavity, a first overflowing channel is formed in the first valve element body, the first overflowing channel communicates with the oil inlet channel and the oil flow channel, the first valve element body comprises a plurality of different rotating positions, when the first valve element body is located at any rotating position, at least one oil flow channel is blocked by the first valve element body and does not communicate with the oil inlet channel; and a production oil nozzle is arranged in the oil flow channel. According to the technical scheme, the problem that production needs to be stopped when the production oil nozzle is replaced in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the field of oilfield exploitation, in particular to a nozzle sleeve and a wellhead device. Background technique [0002] At present, a production nozzle is usually installed in the nozzle casing of the oil production gushing well to adjust the size of the oil flow. When adjusting the working system of the nozzle on site, inspecting the nozzle and removing wax during wax removal and prevention operations, it is necessary to stop the well to cooperate, thereby reducing the production time rate and increasing the work intensity. Contents of the invention [0003] The main purpose of the present invention is to provide a nozzle sleeve and a wellhead device to solve the problem in the prior art that production needs to be stopped when replacing the production nozzle. [0004] In order to achieve the above object, according to one aspect of the present invention, a nozzle cover is provided, including: a base body, having an oil i...
