A wellhead quick thawing device

Abstract

The invention relates to the technical field of wellhead thawing devices, and discloses a wellhead quick thawing device, which includes a right cover, a left cover is movably installed on one side of the right cover, and the connection between the right cover and the left cover Both are fixedly connected with first hinges, the inside of the right cover and the left cover are fixedly installed with a partition, the middle part of the partition is provided with a mounting hole, and the other side of the mounting hole is provided with a cavity , the inside of the installation hole is movably installed with a nozzle, the front end of the nozzle is fixedly installed with an extruding plate, the outside of the nozzle is sleeved with a spring, and the inside of the cavity is movably installed with an air supply pipe. The wellhead rapid thawing device is convenient to use by setting the device in a left and right opening and closing shape, and connecting it through the first hinge, and wrapping the device completely outside the wellhead device for a week, which is convenient for simultaneous heating and thawing of the wellhead device. Increase the defrosting speed of the device, which is convenient for the operator to use.

Description

technical field [0001] The invention relates to the technical field of wellhead thawing devices, in particular to a wellhead quick thawing device. Background technique [0002] Due to seasonal reasons in northern oilfields, for some oil wellhead water-mixed pipelines and water wellhead pipelines, blockages often occur in winter due to internal freezing. The liquid in the pipeline stops flowing, causing a large area of ​​the entire pipeline to freeze, causing oil and gas wells or water wells to stop production. The method can only be used when the freezing of the pipeline is not serious. This method is not only inefficient, but also has potential safety hazards during the operation, and it is easy to burn the operator. [0003] In winter in the northern region, pipelines are often frozen and blocked during construction operations, but open flames are strictly prohibited on the oil well site.

[0002] Due to seasonal reasons in northern oilfields, for some oil wellhead water-mixed pipelines and water wellhead pipelines, blockages often occur in winter due to internal freezing. The liquid in the pipeline stops flowing, causing a large area of ​​the entire pipeline to freeze, causing oil and gas wells or water wells to stop production. The method can only be used when the freezing of the pipeline is not serious. This method is not only inefficient, but also has potential safety hazards during the operation, and it is easy to burn the operator

[0003] In winter in the northern region, pipelines are often frozen and blocked during construction operations, but open flames are strictly prohibited on the oil well site. The common practice on site is to use steam trucks to unblock pipelines with high-temperature steam, but this method has disadvantages: 1. Steam The use of automobiles is expensive, and steam vehicles are frequently used; 2. The steam vehicle equipment takes a long time to prepare, which seriously reduces the work efficiency on site. It often takes a long time to dredge a well, and there are many wells, and the operation is time-consuming and laborious. At the same time, the staff spends a long time Working in a low temperature and windy environment can easily cause frostbite and bring great trouble to the work
