摘要: 为了研究昌吉油田吉7井区稠油热采过程中温度变化对稠油与水相对渗透率的影响,为制定合理的油藏开发方案、预测油水分布关系提供依据,分别应用渗透率为56.38mD、126.54mD、224.98mD的岩心,开展了不同温度(50~200℃)条件下的稠油/水相对渗透率实验。实验结果表明:①在50~200℃之间,束缚水饱和度随温度升高而增大,残余油饱和度随温度升高而减小;②在同一含水饱和度条件下,油相相对渗透率随温度升高而明显增大,随着含水饱和度增加,油相相对渗透率增加的幅度逐渐减小;③当渗透率在50~200mD之间时,岩心渗透率的改变对温度与束缚水饱和度、温度与残余油饱和度以及温度与稠油/水相对渗透率之间的相对关系没有影响。

Abstract: In order to study the effect of temperature on the heavy oil and water relative permeability during the thermal recovery process of heavy oil in Well J7, Changji oilfield, and provide basic data for establishing a reasonable development plan and predicting the oil and water distribution, heavy oil/water relative permeability experiments on the cores with permeability of 56.38mD, 126.54mD and 224.98mD, respectively, were carried out at 50-200℃. The experimental results show that:(1) at 50-200℃, the irreducible water saturation increases with increasing temperature, and the residual oil saturation decreases with increasing temperature; (2) at the same water saturation, the oil relative permeability increases more obviously with increasing temperature; however, with the increase of water saturation, the relative increase of the oil relative permeability decreases gradually; (3) when the permeability is 50-200 mD, the change of the core permeability doesn't influence the relationships between temperature and water saturation, residual oil saturation, and oil/water relative permeability.
