Problems solved by technology

[0003] The traditional wax removal device needs to suspend the oil production process, and then carry out wax removal treatment on the well wall of the oil well, which cannot meet the real-time wax removal on the well wall during the production process, seriously lags behind the production progress, and wastes a lot of resources. In addition, the traditional The wax removal treatment will cause paraffin to still exist in the oil, which requires further separation, complicated operation and low efficiency. At present, there is a lack of a wax removal device that can remove wax in real time. The present invention is a kind of centralized cooling. Oil well wax removal device

Abstract

The invention relates to the related field of oil exploitation, in particular to an oil well paraffin removal device adopting centralized cooling. The oil well paraffin removal device comprises a machine body, the machine body is buried underground, a solidification cavity is formed in the machine body, and material conveying pipes penetrating through the upper end wall and the lower end wall of the machine body are fixedly connected in the end walls of the upper side and the lower side of the solidification cavity. A material conveying cavity communicating with the solidification cavity and the upper end and the lower end of the machine body is formed in the material conveying pipes. Oil can be conveyed from bottom to top through the material conveying cavity during actual work. A coolingdevice used for cooling oil is arranged in the material conveying cavity, and oil is cooled when passing through the device in the oil exploitation process. After the oil temperature is low to the paraffin deposition temperature, paraffin deposition can be performed on the inner wall in the device, and therefore paraffin components in oil are greatly reduced in the device, and paraffin depositionin a well wall during subsequent paraffin transportation is avoided; and paraffin on the inner wall can be scraped off after paraffin deposition is carried out for a certain period of time, paraffincan serve as accessory products of oil exploitation after being recycled in equipment, and the utilization rate of resources is increased.

Description

technical field [0001] The invention relates to the field related to oil exploitation, in particular to an oil well wax removal device using centralized cooling. Background technique [0002] Crude oil contains different amounts of paraffin, which is generally in a dissolved state under the conditions of the oil reservoir. When the crude oil rises from the bottom of the well and flows through the tubing, the temperature and pressure gradually decrease, and the wax gradually precipitates, accumulates, and accumulates on the pipe wall, which is called oil well waxing. , it makes the inner diameter of the oil pipe smaller, affects the production capacity of the well, and shuts down the oil well in severe cases. Therefore, it is necessary to clear the wax on the well wall of the oil well. [0003] The traditional wax removal device needs to suspend the oil production process, and then carry out wax removal treatment on the well wall of the oil well, which cannot meet the real-ti...
