The invention discloses a preparation method of an organic tungsten complex oil product capable of effectively slowing down an attenuation process. The preparation method comprises the following steps: S1, mixing raw materials: selecting heavy crude oil and light mineral oil as base oil; s2, mixing: doping sodium chlorate and naphthenic soap in proportion, and adding calcium carbonate in proportion; s3, filtering: filtering all water and precipitates, and screening impurities formed by sodium hypochlorite; s4, catalytic heating: in the catalytic heating process, mixing and doping linseed oil and maleic anhydride; s5, complexing: adding organic tungsten, and preparing finished lubricating oil through complexing reaction; the lubricating oil is further refined and purified through reduced pressure distillation, separation and purification, organic tungsten is added in the oil product preparation process, the organic tungsten has a polar atomic layered crystal structure, the friction environment ...
