摘　　要：稠油、超稠油油藏进入多轮次吞吐后期普遍存在蒸汽驱替效率低、油汽比低、经济效益差的问题。部分区块由于注汽压力高而导致无法正常注汽。室内实验研究表明 ,伴蒸汽注入SK - 6型高效稠油降粘剂可以明显地降低注汽压力 ,提高注汽周期的产量及油汽比 ,提高蒸汽的驱替效率。该项技术应用于单家寺油田取得了良好的经济效益 ,为提高该类油田的开发效果及经济效益提供了新的途径。Many problems such as low steam displacement efficiency, low oilsteam ratio and poor profit exist generally in heavy oil or super heavy oil reservoirs in late stage of multiple cyclic steam stimulation. Normal steam injection can not be carried out because of high pressure in some districts. The results of laboratory experiment show that steam injection pressure can be reduced obviously, cyclic production, oilsteam ratio and steam displacement efficiency can be improved by using SK-6 highefficiency viscosity reducer. This technology has been widely applied in Shanjiasi oilfield achieving great profit, which provides a new method to exploit this type of oil field.
