Abstract

The invention provides a drop coalescence micro characteristic experiment analysis device in a shear flow field, which comprises a high-speed microscope camera system, a flat-plate pure shear module,a non-uniform shear module, a micro-channel liquid flow shear module and an injection pump, wherein the outlet of the injection pump is divided into three channels, and the three channels are connected with the flat-plate pure shear module, the non-uniform shear module and the micro-channel liquid flow shear module respectively; a circulating liquid supply system is used to provide the circulatingflow function of liquid for the non-uniform shear module and the micro-channel liquid flow shear module; and the high-speed microscope camera system is used to record and analyze the movement, deformation, fracture and coalescence characteristics of drops in the flat-plate pure shear module, the non-uniform shear module and the micro-channel liquid flow shear module. The micro evolution processessuch as movement, deformation, fracture and coalescence characteristics of dispersed drops can be accurately captured, processed and analyzed.

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...
