摘　　要：针对海上油井高含蜡高凝固点的特征,结合蜡沉积影响因素分析,首先运用Wellflo软件不同产液量下的井温变化梯度,同时确定油井对应的析蜡深度。再根据清蜡周期理论方法和SPSS统计法,建立适用于海上KL油田油井清蜡周期预测的新方法,其计算结果与实际生产数据相近;对油田生产过程中清蜡时机选择具有指导意义。The characteristics of high waxy high freezing point of oil wells in offshore oilfield,combined with the analysis of influencing factors of wax deposition. Firstly,use Wellflo software to determine the well temperature gradient under different production volumes,and the corresponding waxing depth of oil wells is determined. According to the wax cleaning cycle theory method and SPSS statistical method,a new prediction method of paraffin removal cycle for oil Wells in offshore KL oilfield was established. The calculation results are similar to the actual production data,which has guiding significance for the timing of wax removal in oilfield production.
