Internal-focusing wax precipitation prevention device

Abstract

The invention discloses an internal-focusing wax precipitation prevention device. The internal-focusing wax precipitation prevention device is composed of a piezoelectric ceramic cylinder, a piezoelectric ceramic cylinder seat, a piezoelectric ceramic cylinder cover, a liquid inlet pipe, a liquid outlet pipe and a pressure monitoring system, wherein the pressure monitoring system consists of a pressure gauge and two plug valves. The opening end of the liquid inlet pipe is connected with a plate type flat welding flange of a pump liquid outlet orifice, and the other closed end penetrates through the piezoelectric ceramic barrel seat and is welded and sealed, and a pipe body in the piezoelectric ceramic barrel seat is uniformly punched; the opening end of the liquid outlet pipe is hermetically connected with a plate type flat welding flange of a cooling box liquid inlet pipe, the other closed end penetrates through the piezoelectric ceramic cylinder cover and is welded and sealed, and aliquid outlet pipe body in the piezoelectric ceramic cylinder is uniformly punched; and a piezoelectric ceramic ring is packaged in the piezoelectric ceramic cylinder body, the bottom end of the cylinder body is in bolted connection with the piezoelectric ceramic cylinder seat welded with the liquid inlet pipe, and the top end of the cylinder body is in bolted connection with the piezoelectric ceramic cylinder cover welded with the liquid outlet pipe. The internal-focusing wax precipitation prevention device has the beneficial effect of determining the matching relationship between the wax content, the flow rate, the temperature and the piezoelectric ceramic power of the crude oil.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to an inner-focusing anti-wax device. Background technique [0002] At present, the wellbore waxing phenomenon in the oil field is relatively serious, and the average wax content of the oil well is above 10%. A large amount is attached to the inner wall of the wellbore or surface pipeline, which increases the flow resistance of crude oil and the load of the pumping unit, reduces pump efficiency, affects production, and even causes production shutdown. Contents of the invention [0003] In view of the above problems, the present invention provides an inner-focusing anti-wax device that utilizes the comprehensive effects of ultrasonic mechanical action, cavitation action, thermal action, etc. to perform wax prevention and wax removal treatment. [0004] The technical solution of the present invention is: an inner focusing type anti-wax device, the anti-wax device is composed o...
