Crude oil heating furnace for oil fields

Abstract

The invention relates to a crude oil heating furnace for oil fields. The crude oil heating furnace is characterized in that a burner (1) is installed below the left end of a casing (2); a combustion chamber comprising a furnace pipe (4) is arranged at the lower part in the casing (2); a cyclone desander (12) is installed at the right end in the casing (2); a crude oil inlet pipe (11) is installed on one side of the cyclone desander (12); a crude oil overflow pipe (13) is installed at the top of the cyclone desander (12); an outlet of the crude oil overflow pipe (13) is connected with an inlet of a heat exchanger coil (14) in the casing (2); and after the heat exchanger coil (14) is bent and coiled in the casing (2), the outlet is connected with a crude oil outlet pipe (10). The crude oil heating furnace can firstly remove solid, such as sand grains and the like, in crude oil, and then heats the crude oil when heating the crude oil, has the characteristics of attrition prevention, blockage prevention, and thermal resistance forming prevention, improves the efficiency, saves the cost, and prolongs the service life of the heating furnace.

Description

Technical field: [0001] The invention relates to a crude oil heating furnace used in an oil field, belonging to the technical field of oil and gas production and equipment design for gathering and transportation.

[0003] The types of heating furnaces mainly include water jacket heating furnaces, fire tube heating furnaces, vacuum heating furnaces, superconducting heating furnaces, phase change heating furnaces, organic heat carrier furnaces, electri...

AI Technical Summary

Problems solved by technology

[0005] The heating furnaces commonly used in oilfields are mainly oil-fired or gas-fired water-jacketed heating furnaces. This kind of heating furnace has the following deficiencies in the process of heating crude oil: First, solids such as sand in crude oil are easy to block and wear pipelines, making them The thickness of the pipe wall is reduced. When the pressure of the pipe exceeds the limit of the pipe wall, leakage or explosion accidents are prone to occur; second, the scaling formed on the inner wall of the pipe causes significant thermal resistance, reduces thermal conductivity, increases fuel consumption, and reduces The working efficiency of the heating furnace; the third is that scale is easy to form on the inner wall of the pipeline, and it is difficult to remove the scale, which will cause corrosion to the pipeline, increase the maintenance workload and maintenance costs of the heating furnace, and reduce the service life of the heating furnace
