The utility model relates to the technical field of optical cable protection, in particular to an optical cable oil corrosion prevention mechanism for petroleum and petrochemical underground communication, which comprises an optical cable, and a protective sleeve is sleeved outside the optical cable. According to the utility model, the protective sleeve and the fixed screw cap are arranged, and the fixed screw cap and the threaded side of the protective sleeve are screwed and connected in a section-by-section manner in actual use and are buried into soil for long-distance optical cable communication; meanwhile, the protection sleeve can protect the optical cable in the protection sleeve from being invaded by leaked petroleum and other soil acid-base substances, and communication blocking caused by corrosion and fracture of the internal optical cable is avoided. And the corrugated casing pipe is corrugated, so that the direction can be changed to facilitate turning installation. Through the arrangement of the
