Description

Technical Field

[0001] The utility model relates to the technical field of oilfield equipment, and particularly relates to a water jacket heating furnace capable of monitoring the corrosion condition in the furnace. Background Technique

[0002] After crude oil and natural gas are produced in oil and gas fields, there is often a large temperature drop from the wellbore to the ground. To prevent the crude oil from solidifying in the pipeline and the formation of hydrates, heating is usually used to increase the temperature. Currently, it is more common to use a water jacket heating furnace to heat softened water and then conduct water bath heating on the oil and gas transmission pipeline to achieve the purpose of temperature increase.

[0003] As the service time of the heating furnace extends, it is found that the outer corrosion of the heating furnace coil occurs, and there is a risk of corrosion perforation. Due to the limitation of the daily monitoring of the heating furnace coil, the furnace chamber cannot be opened for inspection, and real-time monitoring cannot be carried out, resulting in unknown corrosion risk and unclear understanding of the corrosion state, which affects the safe and efficient development of oil and gas fields. Especially for high-sulfur gas fields, after corrosion perforation, hydrogen sulfide leakage will occur, seriously affecting the safe production of the gas field and threatening the life and property safety of the station and surrounding personnel. Content of the Utility Model
