Abstract

The invention discloses an ultrasonic-electromagnetic combined action based viscosity-reducing and paraffin-control device for crude oil and a viscosity-reducing and paraffin-control method of the device, relates to the field of petroleum industry, and aims to solve the problems that the existing methods for reducing the viscosity of crude oil in the processes of being gathered and transported are poor in viscosity-reducing effect and large in energy consumption, and pollute the environment, and the like. According to the invention, a control system respectively sends a frequency signal with a frequency of 25 KHz to two ultrasonic transducers, so that the two ultrasonic transducers generate ultrasonic waves, the control system sends a pulse signal to an inductance coil, so that the inductance coil generates a magnetic field in an oil pipe, a high-frequency oscillation generated by an oscillating circuit is transferred to the two ultrasonic transducers, so that the two ultrasonic transducers and the oscillating circuit generate a high-frequency resonance, and the two ultrasonic transducers generate superposed ultrasonic waves in a middle pipe, so that the crystallization of paraffin molecules is prevented; and due to an induced magnetic field generated by the inductance coil, the liquidity of crude oil is enhanced under the action of the magnetic field, thereby achieving the viscosity reduction of the crude oil. The device and method disclosed by the invention are applied to the viscosity reduction of crude oil.

Description

technical field [0001] The invention relates to a crude oil viscosity reducer. In particular, it relates to a crude oil viscosity reduction and wax prevention device based on ultrasonic and electromagnetic composite effects. Background technique [0002] The wax molecules contained in crude oil components are very sensitive to changes in external conditions, which leads to wax formation in crude oil during the gathering and transportation process. During the long-distance gathering and transportation of crude oil, as the external temperature decreases, the wax in crude oil gradually precipitates And deposited on the inner wall of the pipeline, the effective inner diameter of the oil pipeline is reduced, the transmission capacity is reduced, and finally a wax plugging accident is caused, which seriously affects the normal production and transportation of crude oil. sexual issues. [0003] In order to solve this problem, various measures have been taken at home and abroad. T...
