摘　　要：稠油流变性的研究对稠油开发方案编制、数值模拟、稠油集输和了解稠油在地下的渗流机理等均是非常重要的。该文以单家寺稠油为例 ,深入研究了超稠油的粘温、剪切变稀和屈服值等流变特性 ,总结出了流变特性与温度的关系式。同时研究了超稠油与周边地区普通稠油和特稠油的流变性差别。从流变性的角度 ,提出了超稠油热采的部分技术要求。Study on rheological properties of viscous crude is of great importance to development plan programming of viscous crude,numerical simulation,gathering of viscous crude and the knowledge of seepage flow mechanism underground. Taking viscous crude of Shanjiasi as an example, rheological properties of super viscosity crude are studied thoroughly,including viscosity temperature,shear thinned and yield value. The relational expression of rheological properties and temperatureis summed up. The differences among rheological properties of super viscous crude and ordinary, extra viscous crudearound are studied at the same time. Part technical requirements of thermal recovery in super viscous crude are put forward from the viewpoint of rheololgical properties.
