Thickened oil blending-light mixed tool

Abstract

The invention discloses a thickened oil blending-light mixed tool. The thickened oil blending-light mixed tool includes an outer tube, an injection pipe, a support block, a first joint and a second joint; the first joint and the second joint are separately connected to two ends of the outer tube, the outer tube is sleeved with the injection pipe, and two ends of the injection pipe is closed; the perimeter wall, close to the first joint, of the injection pipe is provided with a thin oil inlet which is used for passing of thin oil into the injection pipe, the perimeter wall, close to one end ofthe second joint, of the injection pipe is provided with a jet hole which is an annular gap formed between an outer tube and an inner tube, and the gap allows the thickened oil to enter from the firstjoint and to flow in the direction of the second joint; the thin oil enters the injection tube from the thin oil inlet and flows in the direction of the jet hole to be ejected from the jet hole, a first-time mixing of the thin oil and the flowed thickened oil is carried out, and mixed oil enters the second joint for a second-time mixing. According to the thickened oil blending-light mixed tool, the thin oil and the thickened oil can be fully mixed, the thin oil consumption is reduced, so that the effect of reducing the energy consumption can be achieved.

Description

technical field [0001] The invention relates to the technical field of oil extraction equipment, in particular to a heavy oil mixed with thinner mixing tool. Background technique [0002] Thinning and viscosity reduction is an important technology in the heavy oil recovery process, and the mixer is the main tool to improve the blending effect in this process. Crude oil has good fluidity under formation conditions, but after entering the wellbore, as the wellbore temperature decreases during the vertical upward flow process, the viscosity of crude oil increases and the fluidity becomes poor, making it impossible for the oil well to be put into production and maintain production. Thinning and viscosity reduction is one of the main forms in the heavy oil production process. The thin oil is injected from the annular space of the oil jacket, and after reaching the point of thinning, it is mixed with the heavy oil and enters the tubing to achieve the purpose of reducing the viscos...

AI Technical Summary

Problems solved by technology

[0004] At present, the common problem of the mixer is that the mixing effect is not ideal, and the phenomenon of slug flow often occurs during the oil lifting process; in addition, the pressure drop of the mixing is large, which causes the energy consumption of the oil pumping system to increase, and the increase of the amount of dilution will cause A large amount of thin oil wasted
