Description

technical field [0001] The invention relates to the technical field of oil recovery, in particular to a polymer dispersion device. Background technique [0002] In order to improve the recovery rate of oilfields, in tertiary oil recovery, polymer flooding is often used to increase crude oil production. The method is to mix polymers and water according to the concentration requirements and then inject them into the ground. However, since the polymer is a supramolecular particle with a large mesh number and a small particle size, and the supramolecular particle has poor fluidity and low water solubility, bridging between supramolecular particles is easy to occur after mixing with water, resulting in agglomeration of supramolecular particles. In order to improve the water solubility of the polymer, it is necessary to disperse the polymer supramolecular particles and then mix them with water. Usually, the polymer supramolecular particles are dispersed by a polymer dispersion dev...

AI Technical Summary

Problems solved by technology

[0005] Since the polymer is a supramolecular particle with a large mesh number and a small particle size, its fluidity is poor. When entering the storage bin, it will adhere to the inner wall surface of the storage bin and aggregate into blocks, which will affect the feeding of the polymer supramolecular particles. The speed of the discharge pipe is not uniform, resulting in a large change in the concentration of the mixture formed by the polymer supramolecular particles and water, and the dispersion of the polymer supramolecular particles dispersed by the above-mentioned device is low.
