Embodiment Construction

[0034] see figure 1 —3. The present invention consists of two parts, a jet acoustic wave oscillator and a vortex injector, which are formed by a cavitation cabin 4 transition butt joint. The cavitation cabin 4 of the present invention is made of a double-headed internal thread pipe joint, and cavitation The chamber 4 can also be formed by extending the tubular housing 11 of the double-jet ultrasonic oscillator or extending the joint part of the guide section 9 of the vortex guide injector. Wherein: the jet ultrasonic oscillator among the present invention has a steel tubular housing 11, the oil inlet end of housing 11 is shaped on screw thread, makes a plug-shaped jet head 1 and is threadedly connected with housing, has on the jet head 1 Two wedge-shaped through-holes 12, 13; the size of each wedge-shaped through-hole 12, 13 in the jet head 1 is 25mm×28mm, and the size of the small mouth is 25mm×3mm; the small-mouth end is designed as a flat nozzle fuel injection port, The sm...

Abstract

The invention relates to a petroleum production auxiliary device, and discloses a parallel-connection type double-sound-wave-vortex viscosity reducing and oil enhancing device for downhole oil pumping. The viscosity reducing and oil enhancing device is formed by connecting a jet flow ultrasonic vibrator with a vortex flow guide ejector in a butt joint mode. A cavitation cabin is arranged between the jet flow ultrasonic vibrator and the vortex flow guide ejector. The viscosity reducing and oil enhancing device is characterized in that the jet flow ultrasonic vibrator comprises a shell, a jet flow head is arranged in the shell, two parallel wedge-shaped through holes are formed in the jet flow head, the small opening ends of the two wedge-shaped through holes are opposite to the cavitation cabin and provided with an outwards-extending support, and the positions, corresponding to the two wedge-shaped through holes, of the support are each provided with a vibration elastic piece to form two parallel ultrasonic vibrators. By means of the viscosity reducing and oil enhancing device, the problems that the wax content is high, blockage is prone to happening, the viscosity of crude oil is high, and mobility is poor are better solved, especially the problem that other existing viscosity reducing devices can not adapt to low deep oil well oil pumping is solved, the oil pumping yield is greatly increased, and the viscosity reducing and oil enhancing device is widely applied to oil well oil production of different types, different wax contents and different water contents.

Description

technical field [0001] The invention relates to an auxiliary device for oil exploitation, in particular to a parallel dual-sonic vortex viscosity-decreasing oil booster used for downhole oil pumping in an oil field. Background technique [0002] In the existing oilfields in my country, the number of medium and high waxy oil wells with a waxy ratio of crude oil of 10-40% accounts for more than 80%. The wax content is high, the crude oil has high viscosity, low fluidity, and is easy to condense and accumulate, thus causing outflow Scaling and clogging of the oil screen and the upper and lower parts of the oil well pump will increase the useless power consumption of the oil well pump, reduce the oil output, and even completely block the wellbore and cause production stoppage. Therefore, how to solve the long-standing problem of paraffin crystal plugging, which is a headache for all oilfields, how to prevent wax, reduce viscosity, and increase the fluidity of crude oil in the wel...
