technical field [0001] This article relates to the field of petrochemical industry, especially a method, device, system, computer equipment and storage medium for joint measurement of emulsification ability and emulsion stability of rotating liquid. Background technique [0002] The test and evaluation of oil-water emulsification ability and emulsion stability have been widely used in food, medicine, chemical synthesis and other fields. For example, in the field of petroleum development, especially in the chemical flooding process containing surfactants, the evaluation of oil-water emulsification ability and emulsion stability plays a vital role in improving the research and application of chemical flooding theory and technology [0003] In the past, the milk making method of oil-water emulsion stability test mainly adopts the hand shaking method, shake the test tube to make the oil and water vibrate up and down to form an emulsion, measure the dynamic curve of the reduction...

Problems solved by technology

Although the emulsion stability evaluation method based on mechanical shaking milk production overcomes the shortcomings of the hand shaking method, the method still has the following shortcomings: ① The emulsification process cannot be judged, only the final result of the emulsification; Reading; ③After the experiment is completed, the emulsification zone needs to be kept still for a period of time to read the emulsification zone, which is not the original emulsification amount, and may break during the waiting process; ④The external input energy of the traditional mechanical milk making process is often constant, which makes it impossible to evaluate the emulsification The minimum disturbance energy that occurs and the effect on emulsification with the change of external energy

However, due to the characteristics of ultrasonic transmission and the complex factors affecting energy attenuation, it is impossible to accurately control and measure the ultrasonic energy and its distribution in the emulsification tube, resulting in uncertainty in the oil-water emulsification position; Using it to evaluate emulsion stability cannot realize the joint measurement of oil-water emulsification ability and emulsion stability

[0005] Aiming at the problem that the current milk-making method cannot accurately evaluate the oil-water emulsification ability and the emulsion stability, a method, device and system for joint measurement of the emulsification ability and emulsion stability of the rotating liquid are needed
