摘要(Abstract)：

为了解决原始稠油储层射频加热技术存在加热距离短的技术难题，提出助剂辅助稠油射频加热技术。在介绍加热机理和工艺的基础上，设计了模拟实验系统并开展了助剂辅助稠油射频加热模拟实验并对稠油温度分布的影响因素进行了研究。结果表明：稠油样品温度随着金属镍粉末和活性炭粉末注入量的增大而升高，但金属镍粉末对稠油样品温度的影响程度较活性炭粉末更大；在助剂使用总量相同的情况下，金属镍粉末和活性炭粉末协同作用比其单独运用时稠油样品的温度更高、射频加热效果更好。研究结果对于射频加热助剂优选和提高射频加热性能提供了指导。
In order to solve technical challenge of short heating distance of radio frequency heating technique in original heavy oil reservoirs, additive-assisted radio frequency heating technique is proposed. Based on introducing heating mechanism and process, simulation experiment system is designed to perform additive-assisted radio frequency heating simulation experiment heavy oil and to study influencing factors of heavy oil temperature distribution. The results show that the temperature of heavy oil samples increases with the increase of injection amount of metallic nickel powder and activated carbon powder, but metallic nickel powder has more influence on temperature of heavy oil samples than that of activated carbon powder. In the case of the same total injection amount of additives, synergistic action of metallic nickel powder and activated carbon powder has better radio frequency heating effect than their separate use,with higher temperature of heavy oil samples. The research provides guidance for optimization of radio frequency heating additives and improvement of radio frequency heating performance.
