摘要： 为了研究近井地带含水率对稠油出砂冷采的影响,在室内模拟了不同含水情况时,恒压下的油水产出规律。实验通过在恒压下将稠油和地层水同时注入人造岩心,研究了渗流机理和产液规律。实验结果表明,在同样的压差下,近井地带的含水率对最终采收率没有影响,这为油田开发方案的设计提供了重要的理论依据。

Abstract: To study the effect of moisture content on cold heavy oil production (CHOP) near wellbore zone, in the lab, the law of oil and water production under constant pressure is simulated when the moisture content is different. By injecting heavy oil and formation water into artificial core simultaneously under constant pressure, the percolation mechanism and liquid production law are studied. Experimental results show that the moisture content near wellbore zone has no effect on ultimate recovery, providing important theoretical basis for the design of oilfield development plans.
