Based on the transient pressure wave method, this paper uses OLGA simulation software to detect CO 2 incomplete pipe blockage, sets different monitoring points in the pipeline, uses its pressure response data for the calculation of blocking position, blocking length and strength, and determines the best monitoring point by analyzing the relative error of specific blocking parameters. For blockage length, when the monitoring point is close to the blockage position, it has the highest measurement accuracy and a relative error of less than 0.535%. Therefore, the monitoring point should be set up separately at the pipe entrance and near the front of the blocking position, so that the internal blockage of the pipe can be detected more accurately and effectively.
