Problems solved by technology

[0003] The existing electromagnetic heater cannot play a protective role when heating the oil well pipeline, so that the internal parts of the electromagnetic heater are easily damaged by external impact during the heating process, and the existing electromagnetic heater does not It is easy to adjust, and the heating range is limited, thereby reducing the heating efficiency. In addition, the existing electromagnetic heater has poor stability, it is not convenient to fix it, and it is easy to shake and shift during the heating process, so it is urgently needed to improve it

Embodiment 1

[0023] see Figure 1-4 , the present invention provides a technical solution: an electromagnetic heater for oil wells with a protective mechanism, comprising a casing 1, both ends of the casing 1 are provided with limit ports 2, the casing 1 can be covered on the oil well pipeline, and Make the two ends of the oil well pipeline fit in the limit port 2 respectively, the bottom of the casing 1 is fixedly connected with the bottom plate 3, and the top of the casing 1 is fixedly connected with the mounting frame 4, and the top inner wall of the mounting frame 4 is fixedly installed with a cylinder 5. The bottom end of the output shaft of the cylinder 5 penetrates through the top of the casing 1 and is fixedly connected with a lifting plate 6. The lifting plate 6 is located in the casing 1, and its bottom is fixedly connected with a transmission rod 7, and the bottom end of the transmission rod 7 is fixedly connected with a The heating cover 8 is provided with an electromagnetic he...

Embodiment 2

[0029] For Example 1, the top of the limit port 2 is arc-shaped, and the inner wall surfaces of both sides are provided with buffer pads 10. The top side wall of the buffer pad 10 is arc-shaped. When the two ends of the oil well pipeline are attached to the limit port 2, the pipe wall can fit in the arc-shaped side wall of the buffer pad 10. The buffer pad 10 is made of sponge material, has elasticity, and can play a buffering role, thereby effectively avoiding the oil well pipeline and the limit port 2. The inner wall is directly contacted to cause collision and wear;

[0030] The top of the limit opening 2 is provided with a fixed plate 11, the fixed plate 11 is fixedly connected to the outer walls of both ends of the casing 1, the bottom of the fixed plate 11 is fixedly connected with a fixed rod 12, and the bottom end of the fixed rod 12 is fixedly connected with a protective plate 13. 13 is an arc-shaped plate structure, and the two ends of the oil well pipeline can be pr...

The device has the characteristics of reasonable structural design, good protection effect, wide heating range, high efficiency, good stability and the like.

Description

technical field [0001] The invention relates to the technical field of oil well heating, in particular to an electromagnetic heater for oil wells with a protective mechanism. Background technique [0002] The electromagnetic heater is a device that uses the principle of electromagnetic induction to achieve heating, and has the characteristics of high efficiency and energy saving, low production cost, and reliable operation. There are many oil wells with low temperature and high viscosity in the oil field. The output fluid of these oil wells will lose some heat during the process of processing and transportation. When the temperature of the output fluid is lower than the freezing point of crude oil, the crude oil will solidify, which will seriously block the pipeline. , causing oil wells to stop and stop production, so such oil wells need to be heated. [0003] The existing electromagnetic heater cannot play a protective role when heating the oil well pipeline, so that the i...
