轮古稠油降粘方法评价

Evaluation on Viscosity Reducing Methods for Lungu Heavy Oil

考察了各种常规井筒降粘技术,如电加热降粘、掺稀油降粘、乳化降粘及降凝降粘剂降粘法,对轮古稠油井区稠油在中高含水期的降粘效果和适用性。结果表明,电加热降粘法不适宜于轮古稠油,乳化降粘法和降凝降粘剂降粘法对轮古稠油的适用性也不理想,掺稀油降粘法是一种适合于轮古中高含水期稠油降粘的技术。

The efficiency and adaptability of various conventional wellbore viscosity reduction techniques, such as electric heating, thin oil blending, emulsification, and using pour point reducer/viscosity reducer, to middle or high water -containing Lungu heavy oil were studied. The results showed that the thin oil blending visbreaking was an adaptive technique for the Lungu heavi oil and other three techniques were not suitable for application in Lungu heavy oil.
