Problems solved by technology

However, most of the well sites now have no associated gas, and the gas heating furnace has been out of service; the use of coal-fired heating furnace not only pollutes the environment, but also has high heating costs, and the heating effect is poor, and digital remote monitoring cannot be realized
Heating with heating cables and various electric heating tubes, the heating efficiency of heating cables is low, and it is difficult to maintain after underground damage, often requiring a large amount of earthwork

The digitalized wellsite crude oil electromagnetic heating device provided by the invention is organically provided with an electromagnetic heating body used for heating crude oil passing through the electromagnetic heating body, a frequency conversion control cabinet being in wire connection with the electromagnetic heating body and used for changing the input power frequency supply frequency and a remote monitoringsystem being in electric signal connection with the frequency conversion control cabinet and used for receiving and transmitting electric signals and controlling starting and stopping of the frequency conversion control cabinet and can conduct one-way internal heating without a heat source and is high in thermal efficiency, safe, friendly to environment and energy-saving. The digitalized well site crude oil electromagnetic heating device and heating method have the characteristics of being high in electric heating thermal efficiency, low in failure rate and easy and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of crude oil heating, and in particular relates to an electromagnetic heating device and a heating method for digital well site crude oil. Background technique [0002] When the crude oil is pumped out from the ground, its temperature gradually decreases due to the influence of the formation and air temperature, especially in the winter when the crude oil is transported in the pipeline, the temperature decreases faster, so it is easy on the inner wall of the oil pipeline outside the wellhead. The phenomenon of wax deposition reduces the effective diameter of the pipeline, increases the back pressure, reduces the system efficiency and pump efficiency, and reduces the production of the oil well. In severe cases, the pipeline will be blocked, causing economic losses and increasing production costs. At present, the way oilfields heat the crude oil at the well site is often to heat the crude oil at the well site ...
