Dynamic evaluation method for water injection quality of cable-controlled separate injection well

The invention provides a cable-controlled separate injection well water injection quality dynamic evaluation method, which comprises the steps of real-time data acquisition of a cable-controlled separate injection well water injection system, and real-time data acquisition and processing. Evaluating faults of a working barrel of the cable-controlled separate injection well, evaluating the health degree of a pipe column of the cable-controlled separate injection well, analyzing and evaluating a water injection result of the cable-controlled separate injection well, and evaluating the risk degree of factors of each stage of the cable-controlled water injection well; and analyzing the interest relationship between different water injection tool factors, water injection condition factors and water injection result factors and the water injection quality of the cable control water injection well. The method can well monitor the state of the working barrel of the water injection well and the health degree of the pi
