1. An integrated composite overload injection system, comprising a feeding mechanism, a composite overload mechanism, a driving mechanism, a booster pump and a mixer, which are provided on a rack, wherein the feeding mechanism comprises a jet tube and is configured to preliminarily mixes water with a main agent and an auxiliary agent of an intelligent energy-gathered oil-displacing agent according to a ratio, an outlet of the feeding mechanism is communicated with an input port of the composite overload mechanism through a first pipeline, the composite overload mechanism is configured for stirring mixing dissolving, and overload ripening a preliminarily mixed solution to form a mother solution, the mother solution is input from an output port of the composite overload mechanism to an inlet of the booster pump through a second pipeline, the booster pump is configured for injecting the boosted mother solution into the mixer, the mixer is configuring for mixing the mother solution and the diluted high-pressure water to form a mixing solution and injecting the mixing solution into an oil-water well, and a first power shaft of the composite overload mechanism and a second power shaft of the booster pump are both driven by the driving mechanism,
wherein the composite overload mechanism comprises a stator barrel and a rotor, a mandrel of the rotor is hermetically supported in the stator barrel by first bearing seats at both ends, an impeller set and an overload bed are provided on the mandrel, a spacer ring for sealing isolation is provided in a middle of stator barrel, the spacer ring isolates the impeller set and the overload bed and divides the stator barrel into a stirring chamber and an overload chamber; the stator barrel is provided with the input port for feeding on a side wall of the stirring chamber, the stator barrel is provided with output port for discharging on a side wall of the overload chamber, the mandrel is provided with mandrel communication hole group for connecting the stirring chamber and the overload chamber at one end of the stator barrel, and one end of the mandrel protruding out of the stator barrel is the first power shaft.
