Discharge aiding agent for fracture acidizing

The invention relates to a discharge aiding method of a discharge aiding agent for fracture acidizing. The discharge aiding method includes the following steps that all components of the discharge aiding agent are mixed and injected into an oil gas well in a time-sharing and asynchronous mode through a mixing device at least provided with an input unit, an injection unit and a control unit; and according to the control information of the control unit, the input unit inputs the components into the injection unit in a time-sharing mode and in a pressurizing mode through designated input pipelines matched with the flow characteristic parameters of the control information. The injection unit comprises a mixing hole channel provided with a first mixer, a second mixer and a third mixer, and at least one input hole formed in the hole wall. Base on the control information which is relevant to time and generated by analysis of the flow characteristic parameters of the components and the component proportion of the dis
