Abstract

A noninvasive method based on ultrasonic velocity was proposed to detect the displacement front in core displacement experiments. CO2 drive experiments were carried out to prove the possibility of detecting the displacement front. The characteristic that ultrasounds have different propagation velocities in different media was used to detect the displacement front in core displacement experiments. The average velocity can be calculated by measuring the first break time of the ultrasonic wave. Arranging all average velocities of different times at a certain position of the core model in chronological order and then finding the catastrophe point, it is the moment of the catastrophe point that the displacement front arrived.
