Heatable pipeline for liquid conveying

Abstract

The invention discloses a heatable pipeline for liquid conveying, and belongs to the technology of pipeline heating. The pipeline is characterized in that a fluid heat transfer device is installed in a cavity of the pipeline; the axial direction of a tubular heat source supply component is parallel with that of the pipeline; the fluid heat transfer device comprises the tubular heat source supply component and a slabby heat pipe; one end, which is along the heat conduction direction of the heat pipe, of the slabby heat pipe is connected with the outer wall of the tubular heat source supply component in a heat transfer way, and the other end of the slabby heat pipe serves as a free end; the connection in a heat transfer way indicates that the slabby heat pipe is directly connected with the outer wall of the tubular heat source supply component; the slabby heat pipe is a slabby heat pipe disclosed in the China Patent 200910207418.9 or the divisional application 201110309983.3 thereof. The pipeline is used for liquid conveying, can properly heat liquid, and is particularly applied to the conveying of liquid easy to solidify.

Description

technical field [0001] The invention relates to pipeline heating technology, in particular to a heatable pipeline for liquid transportation. 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. Replaces direct torch furnaces and tube furnaces. [0004] The working principle of the water jacket heating furnace is: the high-te...

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
