Oil well thermal washing and paraffin removal device

Abstract

The invention discloses an oil well thermal washing and paraffin removal device. A heating furnace is installed on a bottom plate, and a telescopic rod and a hydraulic pillar are mounted on the bottomplate, or wheels are mounted on the bottom plate. A hydraulic control valve, a natural gas purification tank, a water softening device, a plunger pump, an intelligent control box and a power distribution board are installed on the bottom plate, an inlet of the plunger pump and the water softening device are connected, an outlet of the plunger pump is connected with an inlet of the heating furnace, and an electric motor is connected with a power source through a frequency converter. The hydraulic control valve is connected with the hydraulic pillar; an outlet temperature sensor and a pressuresensor are installed at an outlet of the heating furnace, and are connected with a temperature controller, a printer pressure display printer and a control power source by wires. The natural gas purification tank and a gas inlet of the heating furnace are connected. The oil well thermal washing and paraffin removal device has the beneficial effects that a crane is not needed, self-loading and unloading are realized, and associated gas fuel is used as fuel, the fuel is saved, the process operation is safe, and the production life of the oil well is prolonged.

Description

technical field [0001] The invention relates to an oil well cleaning device, in particular to an oil well thermal wax removal device. Background technique [0002] In the crude oil production process of the prior art, the wax contained in the crude oil will continuously precipitate and condense on the oil pipe wall. After a long time, the oil pipe will be blocked. Therefore, the wax removal work should be carried out after a period of time. In the past, a special wax removal car was used, that is, a heating furnace was installed on one car, and a water tank car was equipped in addition. The two cars went to the oil well site together, and the water was heated by the heating furnace and injected into the oil well ring. Heat the oil pipe inside the sleeve to melt the wax accumulated in the oil pipe. [0003] This method requires 20-30 square meters of water, which is a large amount of water. After heating the water and injecting it into the oil well, it will not only pollute ...

Problems solved by technology

[0003] This method requires 20-30 square meters of water, which is a large amount of water. After heating the water and injecting it into the oil well, it will not only pollute the oil layer, but also cause well killing, that is, it will take several days to discharge them when the oil well is in production. , affecting output and causing waste

This kind of heating furnace uses the flame to directly heat the furnace tube, the thermal efficiency is low, and the fuel it uses is diesel oil, so the consumption of diesel oil is relatively large, which not only wastes energy, but also pollutes the air

In addition, if the method of heating the output fluid of the oil well to re-inject the ring sleeve is used to remove wax, sometimes the oil well will produce oil intermittently. At this time, the heating furnace is likely to burn the coil in the furnace red and cause an explosion, so there is also a greater safety hazard. Hidden danger

Some oil wells need to operate for a long time. In order to save a vehicle, after the heating furnace is transported to the oil well, the heating furnace is unloaded from the vehicle and the vehicle can be driven away, but this requires an additional crane , when the work is completed, the heating furnace is hoisted to the truck with a crane to pull it away, which increases the workload of the crane and is also very troublesome
