摘    要:选择2块人造岩心和2块取自于沈北油田的天然岩心,分别在不同条件下饱和地层水,进行了油驱水实验,实验用油具有较高的含蜡量和凝固点;由实验观察可知,温度是决定高凝油渗流特性的决定性因素,当温度高于反常点时,原油呈牛顿流体,粘度在整个渗流过过程不变,反之则呈非牛顿流体,粘度对温度非常敏感,随温度降低,原油粘度升高,油相渗透率和驱油效率降低,在析蜡前后,变化尤为明显;高凝油的渗流特征还受压力梯度的影响,最

关 键 词:高含蜡原油  渗流  流变性  油田  高凝油

Abstract:The crude from Shenyang Oil Field has a high wax content and a high pour point,this makes it difficult to exploit. The permeating characteristics of the high pour point oil has been observed at different temperature in laboratory test. The difference of the permeating characteristics between the temperature above and below the cloud point has been analyzed. It is found that, when it flows through a core at a temperature below the abnormal point,strata waxy damdge will occur. Finally,a suggestion on developing the high pour point and high wax content crude reservoir is given.
Keywords:High wax content oil  Laboratory testing  Percolation  Rheology  Artifical core  Relative permeability  Liaohe Oilfield
