Uniform heating method for use in pipeline

Abstract

The invention provides a uniform heating method for use in a pipeline and belongs to the pipeline heating technology. The uniform heating method for use in the pipeline is characterized in that a fluid heat transfer device for transferring heat from the surface to a fluid in the pipeline is arranged in the cavity of the pipeline; the fluid heat transfer device comprises a tubular heat source supply component and a plate-like heat tube, and the tubular heat source supply component is mounted in the pipeline in the axial direction of the pipeline; one end of the plate-like heat tube in the heat conducting direction is connected with the outer wall of the tubular heat source supply component in a heat transfer way; heat is transferred to the fluid in the pipeline by use of the plate-like heat tube connected with the fluid heat transfer device in the pipeline.

Description

technical field [0001] The invention relates to pipeline heating technology, in particular to a uniform heating method in a pipeline. Background technique [0002] During the process of transporting the mined viscous oil from underground to the ground, the oil will become very thick at the surface temperature and it is difficult to effectively transport it. Therefore, it is necessary to heat the pipeline at the production wellhead so that the oil temperature is controlled at 80°C to 120°C. [0003] The technology and devices for controlling the oil temperature in the transportation process have been continuously improved. In recent years, the water jacket heating furnace has been widely used in oilfield surface engineering due to its reliable safety performance, especially in oilfield wellheads, transfer stations, and combined stations. Alternative to direct torch furnaces and tube furnaces. [0004] The working principle of the water jacket heating furnace is: the high-tem...

AI Technical Summary

Problems solved by technology

The reserves of natural gas are limited, and the consumption of natural gas in the process of oil extraction is neither economical nor long-term for the country and the people, and is not conducive to energy conservation and emission reduction

[0008] 3. Since the place where the water jacket furnace heats the oil pipeline is at the ground engineering point of oil exploitation, natural gas is used as the fuel of the water jacket furnace at the ground engineering point of oil exploitation, and very strict safety management methods must be adopted

However, inserting a heat pipe into a water heater cannot solve the problems of uneven heating of crude oil in the oil pipeline, safety management and shortage of fuel for the heating furnace, etc.

[0012] In summary, the current oil pipeline heating technology has the above defects, and no effective solutions or solutions have been seen
