Description

Technical Field

[0001] This utility model relates to the field of polymer technology, specifically to a device for preparing polymer microspheres. Background Technology

[0002] Polymer microspheres are a commonly used deep profile control technology in oil and gas reservoir development. They rely on displacement fluids to carry microspheres into the deep formation. Through the migration, deformation and sealing of formation pores and throats of the microspheres, the deep fluid flow is diverted, thereby increasing the water drive swept volume and improving the oilfield recovery rate.

[0003] Currently, polymer microsphere preparation typically employs batch reactors, where multiple reactants are mixed and stirred before being discharged. This process is repeated, with the mixture being loaded and reacted again. For example, the polymer microsphere preparation apparatus disclosed in Chinese patent CN210906100U features two stirred tanks arranged vertically to stir the reactants separately. The fluid in the upper stirred tank then flows by gravity into the lower stirred tank for reaction. However, after the reaction, the fluid viscosity increases, causing microspheres to accumulate in the stirred tanks, especially at the lower end cap, making complete discharge difficult. Therefore, cleaning is required after each discharge, which is labor-intensive.

[0004] A search revealed that Chinese utility model patent CN214765348U discloses a device for preparing polymer microspheres, comprising a tank, a stirrer, and a heater. The stirrer is used to stir the solution inside the tank, and the heater is used to heat the solution in the tank. The tank has an inlet and an outlet at the bottom. The device is characterized by a lower end cap at the bottom of the tank, with the outlet located at the lowest point of the lower end cap. The stirrer's shaft is vertically oriented, and a wall scraper is located at the bottom of the shaft, with the scraping blocks of the wall scraper slidingly connected to the lower end cap. The scraper continuously scrapes the inner wall of the lower end cap as the rotating shaft rotates. The device, activated by the agitator, drives the scraper head to rotate, cleaning only a portion of the tank. When the tank contains a large amount of microsphere polymer, stirring is only performed on a single rotating shaft, causing the microsphere polymer to accumulate on the inner wall of the tank, resulting in low stirring efficiency. Therefore, a device for preparing polymer microspheres with uniform stirring and high stirring efficiency is proposed. Utility Model Content

This avoids material accumulation in corners and significantly improves the stirring efficiency of the polymer microsphere material. Attached Figure Description
