Abstract

The invention discloses an array type ultrasonic vibration oil well paraffin removal & control device which comprises an ultrasonic signal generator, an explosion-proof cable, an ultrasonic transducer, and a protective housing. The array type ultrasonic vibration oil well paraffin removal & control device is characterized in that: the ultrasonic signal generator is connected with the ultrasonic transducer through the explosion-proof cable; the protective housing is arranged outside the ultrasonic transducer; the ultrasonic transducer is fixedly connected to the external wall of the outlet pipe of the oil well; distance between the ultrasonic transducers is an integral multiple of the wavelength thereof; the ultrasonic transducers are arranged in an array type on the external wall of the outlet pipe of the oil well. The array type ultrasonic vibration oil well paraffin removal & control device with the mentioned structure has the advantages of a simple structure, simple use method, good paraffin removal & control effects, and strong suitability, and can be used conveniently and effectively for paraffin removal and control in oil wells.

Description

technical field [0001] The invention belongs to the technical field of oil well wax removal and prevention equipment, and in particular relates to an array type ultrasonic vibration oil well wax removal and prevention device. Background technique [0002] In the process of oil exploitation, when the crude oil contains a certain amount of paraffin, it will inevitably form wax deposition in the production pipeline of the oil well. When the amount of wax crystals reaches a certain level, the crude oil loses its fluidity and blocks the flow channel, which stops the oil well and affects the normal production of the oil field. [0003] At present, the commonly used methods to solve wax deposition in oil wells: one is to remove and prevent wax by chemical methods. This method can better solve the problem of wax prevention in production oil wells when the chemical agent and dosage are appropriate, but the cost is high and it is not conducive to the environment. Protect. The second...
