Tubing insulation short joint

The utility model relates to an oil pipe insulation joint used for oil field extraction well with electrically heated oil pipe comprising an upper joint 1, an external sleeve, an upper insulation ring 3, a pressure ring 4, an external stay ring 5, an internal insulation ring 6, an internal stay ring 7, a lower insulation ring 8, a central pipe 9 and a lower joint 10. The utility model is characterized in that the oil pipe insulation joint is installed between a first oil pipe and a second oil pipe; with the bearing function of the external stay ring 5 and the internal stay ring 7 and the insulation function of the lower insulation ring 8, the press ring 4, the internal insulation ring 6 and the upper insulation ring 3, the oil pipe insulation joint can not only bear weight but also ensure the insulation; the utility model can prevent the oil pipe insulation joint from breaking and falling off and avoid the economic loss of well repair; in addition, the utility model can ensure the normal production of the oil well. Therefore, the utility model can be widely used in oil extraction well with electrically heated oil pipe.
