Problems solved by technology

[0009] (2) The axial initial velocity of the liquid in the axial liquid inlet structure is too large, which is not conducive to increasing the effective residence time of the separation medium in the separation chamber
[0011] (3) The small diameter of the drum limits the ability of the dynamic cyclone to generate centrifugal force
However, under the same diameter, the greater the length of the drum, the more difficult it is to ensure its coaxiality. During the separation process, when the drum rotates at a high speed, the degree of deviation between the geometric center of the drum and the center of rotation affects to a large extent. final separation effect
At the same time, due to the increase in length, the influence of system vibration on the flow field is aggravated. In severe cases, the separated light and heavy phases may be remixed at the outlet.
[0015] Based on the above analysis, it can be seen that the adoption of the axial liquid supply structure has brought many adverse effects on the separation effect of the dynamic cyclone, which seriously restricts the development of the dynamic cyclone technology. This can also explain why after more than ten years of research, The technology is still not widely used

Abstract

A vertical dynamic cyclone separator for removing sand from thick oil and separating the oil-displacing polymer from the recovered liquid by gravitation and centrifugal is composed of a frequency-variable motor, a vertical cyclone separator with a rotary drum driven by said motor, and a settling tank for collecting the separated heavy phase.

Description

technical field [0001] The invention relates to a vertical dynamic cyclone used for heavy oil desanding and polymer flooding production liquid separation in the field of petroleum production. Background technique [0002] At present, a large number of heavy oil reservoirs have been discovered in 15 large and medium-sized oil-bearing basins and regions such as Songliao, Bohai Bay, and Zhungeer, and the geological reserves of heavy oil reservoirs in my country are predicted to be as high as 80×10 8 m 3 Therefore, in the future oilfield development, our country's heavy oil production potential is huge. However, because the compaction diagenesis of heavy oil reservoirs is generally poor, the reservoir cementation is loose, and the binding ability between sand particles is poor. Under the action of high pressure gradient in the oil recovery process, sand particles are prone to fall off, and the viscosity of crude oil is generally High sand-carrying capacity, resulting in very c...
