The invention relates to a method for analyzing gas dissolved in oil by a gas sensitive sensor based on a Mn-MoS2 material. The method comprises three parts, namely model building, adsorption of the gas dissolved in the oil and sensing behavior prediction. In the model building part, firstly, a Dmol3 module of molecular simulation software Material Studio software is used for building a unit cell model and a model used for optimizing and calculating unit cells, then an adsorption model of the three gases of CO, CH4 and C2H2 is built, an Mn-MoS2 single-layer unit cell structure is optimized, after a stable adsorption model is obtained, the three gases of CO, CH4 and C2H2 are placed on the surface of Mn-MoS2, and the model is optimized, so that the adsorption model of the three gases of CO, CH4 and C2H2 is obtained. After the model with the lowest energy is obtained, the adsorption parameter of each gas is analyzed, and the adsorption effect of Mn-MoS2 on the gas is verified. The method has the advantages of be
