description The invention belongs to the technical field of petroleum engineering and well logging, and particularly relates to a dynamic measurement error compensation method for measuring oil holdup by a split-flow method. The method comprises the following steps: 1, carrying out a split-flow method oil-water measurement experiment, setting the theoretical oil holdup of the t experiment as Vt, settingthe measured actual oil holdup as Vft, and calculating the oil holdup dynamic measurement error delta Vt; 2, identifying and correcting the abnormal value of the oil holdup dynamic measurement error delta Vt by adopting a grey system theory; 3, performing digital addition and anti-pleat preprocessing operation on the corrected oil holdup dynamic measurement error delta, wherein the processed oil holdup dynamic measurement error is delta; 4, establishing an oil holdup dynamic measurement error prediction model according to the digital addition and anti-pleat preprocessed oil holdup dynamic measurement error delta; and 5, co
