Multi-stage rotational flow and vortex anti-blocking oil increasing device

Technical Field

The utility model relates to an oil production equipment field specifically is a stifled oil increasing device is prevented to multistage whirl, vortex.

Background

At present, in the later stage of production of crude oil, high-pressure water is injected into an underground oil layer from the ground or chemical substances capable of displacing oil are added into the water, which is called a water-flooding or compound oil-displacing mode, so that the formation temperature is lower and lower due to long-term water injection, the flowing speed of the crude oil is slowed, the viscosity is increased, components such as paraffin, colloid asphalt and the like in the crude oil are more easily gathered and adsorbed on the wall of an oil pipe at low temperature, and the oil pipe is thicker and thicker, thereby causing the blockage of the oil pipe. If the oil extraction is not cleaned in time, the load of the sucker rod is increased and the sucker rod is broken, or the production is stopped due to the blockage of an oil pipe.

Outer whirl cover includes the sleeve, and sleeve lateral wall equipartition has the helicla flute of a plurality of and sleeve inner wall intercommunication, the width of helicla flute reduces gradually after to in the past.

Inner strata whirl post core includes the end plate, and end plate one end is equipped with the post core, and post core outer wall equipartition has a plurality of helicla flutes, be equipped with the feed liquor hole with the helicla flute intercommunication on the end plate.

The fan blade is provided with a plurality of long through holes.

The working principle of the utility model is as follows: an oil inlet at the front end of the pipe shell is connected with an oil pumping pipe, an oil outlet at the rear end of the pipe shell is connected with an oil well pump, when oil pumping is carried out, produced liquid firstly passes through a swirler A, the flow velocity is instantly improved to a proper speed, meanwhile, the produced liquid is instantly cut and refined when passing through a long through hole of a fan blade, then the produced liquid is divided into two parts when reaching a layered rotational flow mechanism, and one part of the produced liquid moves to a primary turbulent flow cavity along an inner layer rotational flow channel and then passes through a swirler B, and finally enters a secondary; the other part of the oil liquid moving along the outer layer rotational flow channel directly enters the secondary turbulence cavity, the two oil liquids are mixed in the secondary turbulence cavity to further generate turbulence, the produced liquid is mixed and collided in the turbulence cavity, so that massive paraffin, colloid asphalt and other components are dispersed and surrounded by water molecules to form oil-in-water emulsion, and the paraffin, the colloid asphalt and other components in the crude oil are not easy to gather and are adsorbed on the wall of the oil pipe, so that the blockage of the oil pipe is avoided, and the fluidity of the produced liquid is enhanced.

The utility model discloses following beneficial effect has: the multi-stage vortex device improves the flowing speed of oil when the oil passes through the multi-stage vortex device and is cut and refined by the fan blades to form a vortex state, improves the fluidity of crude oil through the internal and external layered cyclone structures, emulsifies the produced liquid through the two-stage turbulent cavity, avoids the adhesion on the pipe wall, greatly improves the wax-proof viscosity-reducing effect, improves the efficiency of an oil well pump and hardly prevents the oil pipe from being blocked.
