Abstract

The invention discloses an electromagnetic heating device for an oil well, which has the advantages of high heat efficiency, fast heating speed and satisfying the demands of oil recovery and oil transfer in low-temperature environment and the like, wherein the device is structured to comprise a fixed bracket which is provided with a heating cylinder communicated with an inlet pipe and an outlet pipe, the heating cylinder is provided with the electromagnetic heating device thereon which is connected with a power supply device; and temperature measurement devices are respectively arranged on the inlet pipe and the outlet pipe and are connected with a control device connected with the power supply device.

Description

technical field [0001] The invention relates to an electromagnetic heating device for oil wells, which belongs to oil production devices for oil wells in oil fields. Background technique [0002] At present, with the deep development of oil reservoirs, the number of heavy oil wells and high pour point oil wells is increasing. In the process of oil extraction and oil transportation, heavy oil and high-condensation oil will solidify, wax and block at low temperature, which makes oil recovery and oil transportation unable to produce normally. [0003] In the prior art, gas-fired boilers or coal-fired boilers are usually used to heat water or steam, and the hot water or steam is injected into the oil well from the oil pumping port to dilute or dissolve the heavy oil and condensed oil to maintain normal oil pumping. By wrapping the electric blanket on the oil pipeline, the oil pipeline is heated to dilute the heavy oil and high pour point oil, so as to ensure the normal oil tran...
