A paraffin-prevention and
viscosity-reduction
rectifier of an
oil field flowing well is suitable for extracting oil from an
oil field high-pressure well, and the long-standing, big and difficult problem that paraffin and scale of a flowing well are scraped and removed through manual work since the beginning of the oil exploitation history is solved. The
rectifier is a tubular tool and mounted in the position about one thousand meters under a paraffin-troubled well section of the well. A first-level vortex
rectifier body, an impinging
stream phase mixing device, a second-level vortex rectifier body, an
impact type acoustic oscillator and a third-level vortex rectifier body are mounted in the rectifier from bottom to top, a large-cluster laminar-flow condensed
phase state of flowing oil, gas and water can be treated to form a fine-cluster milky eddying turbulence
phase state, all heterogeneous components are made to wrap one another, refining, scattering and shielding of paraffin crystals and scale crystals are achieved, the physical state, the
physical property, the flow state and the flow speed of produced liquid are optimized, and the phenomenon that the well is blocked by gathered paraffin and scale crystals on the oil tube wall is fundamentally eliminated; and meanwhile, the
viscosity of the produced liquid is greatly lowered, the in-well burble procedure is effectively prolonged, manual paraffin and scale scraping and removing are omitted,
workover treatment is reduced, oil extraction cost is lowered, and production and efficiency are improved.
