Abstract

The invention provides an experimental analysis device for droplet aggregation and microscopic characteristics in a shear flow field, including: a high-speed microscopic camera system, a flat plate pure shear module, a non-uniform shear module, a microchannel liquid flow shear module, and a syringe pump The outlet of the syringe pump is divided into three paths, which are respectively connected with the flat plate pure shear module, the non-uniform shear module and the microchannel liquid flow shear module; the circulating liquid supply system is used for the non-uniform shear module and the The microchannel liquid flow shearing module provides the circulating flow function of the liquid; the high-speed micro-camera system is used for recording and analyzing the movement of droplets in the plate-level pure shearing module, the non-uniform shearing module, and the microchannel liquid flow shearing module. Motion, Deformation, Fracture, Merge features. The invention can accurately capture, process and analyze the microcosmic evolution process of movement, deformation, rupture and coalescence of dispersed droplets.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to an experimental analysis device for droplet aggregation and microscopic characteristics in a shear flow field. Background technique [0002] In the process of crude oil extraction, it is easy to form oil-in-water or water-in-oil emulsion. This is because natural active substances such as colloids and asphaltenes in crude oil, as well as surfactants added during the mining process, easily cause an oil-water interface film with a certain mechanical strength to exist on the surface of the dispersed phase droplets, thus giving the dispersion liquid The droplets gather and cause obstruction. [0003] At present, gravity sedimentation and cyclone separation are important ways to realize oil-water separation. However, with the change of crude oil extraction methods in oilfields, the properties of produced fluids have changed, and the separation efficiency of traditional...
