摘　　要：为了提高中深层地热能供热潜力评估性能,提出了一种基于改进大数据频繁项集挖掘算法的中深层地热能供热潜力评估方法。利用普通类间距离和准则、加权类间距离和准则,挖掘出用于供暖潜能评估的频繁项集条件模式基,将条件FG-tree视为一种递推处理过程,挖掘中深层地热能供热潜力数据的频繁项集。利用单位供热量能量消耗指标和能量效率指标,分析了地热能供热的能量,通过[火用]效率指标和能级平衡系数指标,实现中深层地热能供热潜力评估。实验结果表明,所提出的方法能够评估中深层地热能供热潜力,并具有更高的评估效率。In order to improve the evaluation performance of geothermal heating potential in the middle and deep layers,an evaluation method of geothermal heating potential in the middle and deep layers based on improved big data frequent itemsets mining algorithm is proposed.Based on the general and weighted inter-class distance sum criteria,the conditional pattern base of frequent itemsets for heating potential evaluation is mined,and the conditional FG-tree is regarded as a recursive processing process to mine the frequent itemsets of geothermal heating potential data in the middle and deep layers.Based on the energy consumption index and energy efficiency index of unit heat supply,the energy of geothermal energy heating is analyzed,and through the exergic efficiency index and energy level balance coefficient index,the geothermal energy heating potential evaluation is realized.The experimental results show that the method can evaluate the heating potential of middle and deep geothermal energy,and has higher evaluation efficiency.
