摘　　要：针对安岳区块结蜡问题,选取代表性气井岳101井,通过实验发现,岳101井样品重质组分含量少,油品密度低、黏度小、蜡质含量低,含蜡量为2.06%,常压下析蜡点为17℃。结合实验数据进行结蜡预测,得出岳101井在井筒内不会产生结蜡问题,结蜡只能发生在地面管线的低温地带。In view of the problem of wax deposition in Anyue block,the representative gas well Yue101 is selected.Through the experimental research,it is found that the sample of Yue101 has less heavy components,low oil density,low viscosity,low wax content,the wax content is 2.06%,and the wax precipitation point is 17℃ under normal pressure.Combined with the experimental data,the wax deposition prediction was carried out,it is concluded that there is no wax deposition problem in the wellbore of well Yue 101,and the wax deposition can only occur in the low temperature zone of the surface pipeline.
