摘　　要：稠油的流动性差 ,粘度大 ,开采的关键问题是降粘、改善其流动性。胜利油田根据不同油藏的条件选择了多种降粘开采方式 ,逐步建立并形成了具有自己特点的稠油油藏水驱开采技术和热采技术。稠油油藏水驱开采技术主要包括机械降粘、井筒加热、稀释降粘、化学降粘、微生物单井吞吐、抽稠工艺配套等 ;稠油油藏热采技术主要包括蒸汽吞吐、蒸汽驱、丛式定向井及水平井、火烧油层以及与稠油热采配套的其它工艺技术等。The critical problem in heavy oil production is high viscosity and poor flowability. In Shengli oilfield, many recovery modes of viscosity reduction had been selected according to different reservoir conditions, and gradually, unique methods of water flooding and thermal recovery suitable for this field had been worked out. Techniques of water flooding mainly include mechanical viscosity reduction, wellbore heating, dilution and chemical viscosity reduction, microbial huff and puff, and accessory technique of heavy oil pumping; techniques of heavy oil thermal recovery mainly include steam huff and puff, steam drive, directional cluster well and horizontal well, in situ combustion and other accessory techniques.
