1. The leakage protection function of the electromagnetic heater control box should be tested at least several times a month. It should be sensitive and reliable. When the automatic power supply and heating cannot be performed, the cause should be checked and the fault should be eliminated. Quasi-forced AC contactor pull-in.
2. The pumping frequency of oil wells is high and the time is long, the liquid production volume is low and the oil flow rate in the pipeline is slow. In addition, there is no water for circulation, so the heating process method of multi-well confluence and common electromagnetic heater should be adopted to prevent electromagnetic heating. The electromagnetic heater is damaged due to the high back pressure caused by the long-term transportation of the pipeline and the frequent thermal protection working state for a long time.
3. Before high-pressure cleaning pipelines and well flushing operations, open the bypass cut-off door in advance, close the electromagnetic heater inlet and outlet cut-off door, and cut off the power supply of the control box to prevent the electromagnetic heater from being damaged by high-voltage impact and causing unnecessary damage. loss.
4. In winter workover operations or when the electromagnetic heater is out of use for a long time, it is necessary to cut off the power supply of the control box.
5. The safety protection device of the electromagnetic heater should be checked every year to ensure the safety of the device. Action sensitivity. According to the actual situation of Santanghu Oil Production Plant, the double overheating protection device of the wellhead heater and the overheating protection device of the oil tank heater should be replaced once more than one year, so as to prolong the service life of the electromagnetic heater and ensure safe and reliable operation.
6. In the heating environment where the pipeline liquid flow is insufficient or the gas resistance phenomenon occurs frequently, the automatic constant temperature power adjustment control cabinet should be selected as much as possible to reduce the long-term abnormal dry burning of the heater and the harshness of anti-dry burning. Running state, so that the heater edge medium accelerates aging and even affects its edge performance, which directly affects its normal service life and service life.
