Technical Field
[0001] This utility model relates to the field of oilfield technology, specifically a new type of environmentally friendly and energy-saving electric heating device for oilfields. Background Technology
[0002] An oil field is a naturally formed underground oil accumulation area with a unified pressure system and clear boundaries, which can be developed in a unified manner. Based on geological control factors, oil fields are divided into three categories: structural oil fields, formation oil fields, and composite oil fields. As a non-renewable energy treasure, the development of oil fields is related to energy security and the economic lifeline.
[0003] Regarding the aforementioned and existing related technologies: During oilfield extraction, it is necessary to electrically heat the oil pipes to replace steam heating and reduce emissions from coal-fired boilers. Electric heating increases the wellbore temperature, and the viscosity of crude oil decreases exponentially with increasing temperature. However, since most heating belts lack external insulation structures, they are prone to excessive heat dissipation when used outdoors, affecting heating efficiency. Therefore, a new type of environmentally friendly and energy-saving electric heating device for oilfields is proposed to address these issues. Utility Model Content
