摘要
为了解决油稠井易结蜡,频繁卡泵、井筒举升困难、单井耗电高等技术难题,运用热传导学基本理论,通过设计一种结合生产实际的电加热井优化设计方法,对电加热制度进行了优化。通过优选电加热功率、优化电加热带下入参数、将连续电加热改为间歇电加热制度,有效降低了单井能耗,同时通过考虑避免结蜡、卡泵等因素进一步优选出合理的加热功率及间歇加热时间,有效的避免了高凝固点油井因电加热设备温度过低或停止加热时间过长造成生产井结蜡、卡泵等举升问题。试验区高凝固点油井经过电加热制度优化后,单井日综合耗电从连续电加热的531.4 kWh下降到351.0 kWh,实现了节能高效运行,为稠油井的经济有效开发提供了一种新思路。
In order to solve the problems of wax formation, frequent stuck pump, difficulty in wellbore lifting, and advanced technology of power consumption in single well, the electric heating system was optimized by using the basic theory of heat conduction and designing an optimal design method of electric heating well combined with actual production. Through optimizing electric heating power, optimization of electrical heating taken down into the parameters, the continuous electric heating instead of intermittent electric heating system,effectively reduce energy consumption of a single well,at the same time by considering avoiding wax, factors such as stuck pump is further optimized reasonable rest between heating power and heating time, effectively avoid the high freezing point oil well because of the low temperature electric heating equipment or stop heating time is too long cause production Wells wax, such as stuck pump lifting problem. After the optimization of the electric heating system in the high-freezing point oil Wells in the test area, the daily comprehensive power consumption of a single well decreased from 531.4 kWh of continuous electric heating to 351.0 kWh, which realized the energy saving and efficient operation and provided a new idea for the economic and effective development of heavy oil Wells.
