The invention discloses a petroleum pipeline cutting mark belt comprising a steel belt piece, wherein a rectangular connecting head is installed at one end of the steel belt piece, a steel column protruding outwards is arranged at the center of the rectangular connecting head, and a positioning screw hole is formed in other end of the steel belt piece, opposite to the rectangular connecting head; multi-level positioning holes are formed in the surface of the steel belt piece, horizontal fixed mounts are respectively arranged at the two end parts of the steel belt piece, and steel claws are respectively arranged at two ends of each horizontal fixed mount. The petroleum pipeline cutting mark belt has the beneficial effects that a steel belt is wound on a pipeline and is connected end to end, so that the steel column is inserted into the proper positioning hole and is screwed, a slate pencil draw lines on the pipeline along the edge of the stainless steel belt, and then the pipeline is cut; the time and the labor are saved, and the parallel and level degree and the airtightness of the subsequent cutting can be ensured; due to the arrangement of the two levels of horizontal fixed mounts and the configuration of the corresponding steel claw, the condition that a cutting belt can not be moved anymore in the whole line drawing process can be ensured.
