The invention discloses an implementation method of a marine dual-fuel oil gas multi-point fuel gas injection control system. The implementation method comprises an implementation method of a calibration process, a correction calibration method of small-pulse-width injection oil quantity of electronic control unit pumps of all cylinders and an implementation method of a pure diesel oil-dual-fuel switching process. The implementation method has the following advantages: under the working condition of high substitution rate, fuel gas speed regulation is used as a main part, diesel oil speed regulation is used as an auxiliary part, and the main part of fuel is used for speed regulation, so that the stability of the rotating speed of the engine is improved; and due to the fact that fuel gas is used for speed regulation, the replacement rate of the engine is further increased, the service life of the engine is prolonged, the combustion state is consistently improved and optimized, and the emission index is improve
