Description

TECHNICAL FIELD

[0001] The utility model relates to oil and gas field exploitation technical field, concretely is a kind of oil pool crude oil fluidity reinforcing device based on electromagnetic heating. BACKGROUND

[0002] In the exploitation, refining and transportation process of crude oil, contaminated crude oil often occurs due to various reasons, which is usually temporarily stored in an open-air oil pool to meet the demand of crude oil refining after treatment. However, in winter, the pumping and transportation of crude oil become a problem. The physical properties of crude oil in the oil pool change significantly at low temperature, especially its fluidity and viscosity. The paraffin and asphaltene components in the crude oil will precipitate and form solid crystals at low temperature, resulting in a sharp increase in the viscosity of the crude oil and a significant decrease in its fluidity. This phenomenon is particularly common in oil fields, oil wells and long-distance crude oil transportation pipelines in cold regions, which seriously affects the efficiency of crude oil transportation. When the temperature of the crude oil is lower than its flow point, the crude oil becomes extremely viscous, and even solidifies, which not only hinders the normal flow of the crude oil, but also causes problems such as pipeline blockage and pumping difficulty, increasing the difficulty and cost of crude oil processing and transportation.

[0003] To solve this problem, traditional heating methods such as electric heating rod heating and heat conducting oil furnace heating are widely used for heat preservation and heating of crude oil pipelines. However, these methods have many limitations, such as high energy consumption, low heating efficiency, complex operation, high maintenance cost, etc. The heating elements of traditional electric heating rod heating and heat conducting oil furnace heating are in direct contact with flammable liquids such as crude oil and heat conducting oil. Once a fault occurs, a safety accident is likely to occur. In addition, these heating methods usually only act on the oil pump pipeline of the oil pool, and cannot heat and reduce the viscosity of low-temperature high-viscosity crude oil from the source, making it difficult to effectively solve the problem of pumping difficulty of the oil pump in the oil pool in low-temperature environment.

[0004] An oil pool crude oil fluidity enhancing device based on electromagnetic heating is proposed to solve the problems mentioned above. UTILITY MODEL CONTENTS
