The invention discloses a separate injection well whole shaft test process pipe column which comprises a shaft body and an oil pipe column, threaded rods are fixedly connected to the two sides of the top of the oil pipe column, fixing sleeves are connected to the outer sides of the threaded rods in a threaded mode, and the ends, away from the oil pipe column, of the fixing sleeves abut against the inner wall of the shaft body. The optical cable fixing device is compact in structure, easy and convenient to operate and high in practicability, an optical cable can be rapidly fixed to the inner wall of a full-wellbore testing process pipe column of a separate injection well by arranging the fixing mechanism, meanwhile, the optical cable can be rapidly fixed to the inner wall of the full-wellbore testing process pipe column of the separate injection well in cooperation with the positioning mechanism, and the positioning accuracy is improved. The vertical position of each fixing node can be freely changed, so that
