The invention discloses a lining heat-insulation heat-preservation oil pipe. The oil pipe is composed of steel oil pipe bodies, pressure bearing inner pipe bodies embedded in the oil pipe bodies, a heat-insulation heat-preservation layer covering the pressure bearing inner pipe bodies, a sizing protective belt winding the exterior of the heat-insulation heat-preservation layer, and oil pipe couplings. According to the oil pipe, the pressure bearing inner pipe bodies are covered with the heat-insulation heat-preservation layer and wound with the sizing protective belt and then jointly penetrate into the oil pipe bodies; and through downward sliding prevention forced seal devices and forced seal devices which are arranged at the two ends of the oil pipe bodies and the pressure bearing inner pipe bodies correspondingly, the pressure bearing inner pipe bodies and the heat-insulation heat-preservation layer are fixed in the oil pipe bodies, and finally through the oil pipe couplings, the multiple oil pipe bodies are connected together to be place into a well for using. According to the lining heat-insulation heat-preservation oil pipe, the loss of the temperature of crude oil in the process that the crude oil is lifted up from the well bottom to a well mouth can be effectively reduced, the flowing state and wax precipitation of the crude oil in a shaft are improved, the temperature of the crude oil of the shaft and the well mouth is increased, the ground gathering and transferring process is simplified, the load of a pumping unit is reduced, and finally the purposes that energy is saved, emission is reduced, profits are generated, efficiency is improved, and oil exploitation cost is greatly reduced are achieved.
