The utility model belongs to the technical field of the oil field, concretely relates to anti -freezing knot oil well pipeline, battery, protective layer, insulating layer, temperature sensor, the pipeline body, coil and pressure sensor are drawn together to this oil well pipe solenoid, external portion sets gradually insulating layer, coil and protective layer at the pipeline, external portion still is provided with the battery at the pipeline, internal portion is provided with temperature sensor or / and pressure sensor at the pipeline, the battery is coil, temperature sensor or / and pressure sensor power supply, the utility model discloses anti -freezing knot oil well pipeline, it is consequently low to below the fusing point of oil when the temperature because the design is provided with temperature sensor or / and pressure sensor in pipeline internal portion, or pipeline body internal pressure is greater than the critical value, personally experiences sth. Part of the body for the pipeline with regard to the actuating coil, effectively avoids the emergence of the oil well pipeline problem of congealing.
