Automatic grease injection system and exploitation system

An automatic grease injection system comprising:

• a hydraulic power source assembly configured to output grease injection power hydraulic oil;
• a plurality of grease injection structures driven by the hydraulic power source assembly to separately output sealing grease;
• and
• a controller signally connected to the hydraulic power source assembly and the plurality of the grease injection structures to receive state signals of the hydraulic power source assembly and the plurality of the grease injection structures and to output control signals to the hydraulic power source assembly and the plurality of the grease injection structures,
• wherein the automatic grease injection system and a fracturing manifold form a skid together, and the plurality of the grease injection structures are butted against a plurality of structures to be injected with grease on the fracturing manifold respectively.

An automatic grease injection system comprising:

• a host structure comprising a power structure and a grease injection structure, in which the power structure drives the grease injection structure to output sealing grease;
• a shunting structure comprising a control valve and a connecting pipeline which comprises a plurality of shunting branch pipes and a grease injection main pipe which are connected to each other, in which the grease injection main pipe is connected to the grease injection structure, each of the shunting branch pipes is connected to a structure to be injected with grease, and the sealing grease output by the host structure is selectively connected to the structure to be injected with grease through the shunting structure;
• and
• a controller signally connected to the host structure and the shunting structure to receive state signals of the host structure and the shunting structure and to output control signals to the host structure and the shunting structure,
• wherein the grease injection structure comprises:
• a grease injection pump configured to pump sealing grease into the grease injection main pipe;
• a booster pump configured to supply pressurized hydraulic oil to a grease injection pressurization structure;
• and the grease injection pressurization structure configured to perform grease injection pressurization with the pressurized hydraulic oil as a power source.
