摘要
重质高粘原油在地层条件下表现为非线性渗流 ,其流变性测试结果对于指导其油藏的开发具有重要意义。对孤岛油田东区重质高粘原油渗流流变性进行了研究。结果表明 ,该区含气原油为假塑性流体 ,地层条件下非线性渗流显著 ;脱气原油粘弹性较弱 ;注水开发时 ,油水井间的水驱速度应控制在 0 .
Seepage flow of heavy crude with high viscosity at formation conditions displays nonlinear feature. Test results of its rheological property are of great importance for guiding the development of its oil reservoir. Rheological property of heavy crude with high viscosity in east area of Gudao oilfield is studied. The result shows that live crude in this area is pseudoplastic fluid, nonlinear seepage flow is remarkable at the formation conditions; viscoelasticity of degassed crude is weak; water drive velocity between oil well and water well should be less than 0.885m/d in waterflood development.
