Abstract
An efficient generation and performance evaluation device of foam under high temperature and high pressure is provided, the device includes: a reaction kettle, a water bath thermostatic box, a porous hollow steel circular plate, a rotator, a multilayer spiral steel wire mesh, a spring hinge, a gas diffuser with vortex shape, a light-emitting diode (LED) lamp, valves, a screw pump, a pressure transmitter, a temperature transmitter, a fluid reservoir, a gas reservoir and a data collection and analysis device. The device determines a foamability and stability of the foam by injecting foam solution and gas into the reaction kettle, observing a foaming volume and a half-life period of the foam after the gas in full contact with the foam solution to generate the foam, and the device can determine oil resistance and salt resistance of the foam under high temperature and high pressure.
