Spiral shearing viscosity-reducing cyclone separation device

Abstract

The invention discloses a spiral shearing viscosity-reducing cyclone separation device. The problem that in the oil-water separation process, the oil viscosity is too high, and the oil-water separation performance is greatly influenced is solved. The device is characterized by further comprising a flange type viscosity-reducing spiral flow channel (1), an oil flow pipe (2), a secondary spiral flowchannel (3) and a large gasket (4). The flange type viscosity-reducing spiral flow channel (1), the secondary spiral flow channel (3), the large gasket (4) and a cyclone separation device shell (5) are combined and fixed through bolts and nuts, and the oil flow pipe (2) is inserted into a cavity of the flange type viscosity-reducing spiral flow channel (1) and a cavity of the secondary spiral flow channel (3). The flange type viscosity-reducing spiral flow channel (1) is matched with the secondary spiral flow channel (3) through a flange (10). According to the device, a spiral shearing viscosity-reducing cyclone separation structure is provided, the oil-water viscosity can be reduced through spiral separation of a primary spiral flow channel and the shearing effect of a viscosity-reducingbaffle before oil-water separation, oil and water are efficiently separated in the secondary spiral flow channel, and the applicability of the separation device is enhanced.

Description

technical field [0001] The invention relates to a device used in the fields of petroleum, chemical industry and the like for separating oilfield production liquid or sewage. Background technique [0002] With the continuous development of oilfields, the development of many onshore oilfields has entered the middle and later stages, and the water content of oil wells is getting higher and higher, and the water content of many oil wells is greater than 95%. Therefore, how to deal with the produced water is a difficult problem that many oilfields have to face. With the deepening of research, a complete set of oil-water separation devices based on cyclone equipment has been basically formed. The cyclone separator used for oil-water separation has shown a good separation effect in the downhole environment. However, the separation effect is limited due to the high viscosity of oil and water. If the oil-water viscosity is too high, the density difference between oil and water will ...

AI Technical Summary

Problems solved by technology

However, due to the high viscosity of oil and water, the separation effect is restricted

If the viscosity of oil and water is too high, the density difference between oil and water will decrease, and many small oil droplets cannot coalesce into larger oil droplets, so that oil and water cannot be separated better, and the efficiency of oil and water separation is reduced.
