摘　　要：针对辽河油田超稠油油井蒸汽吞吐轮次高、吞吐效果逐渐变差的特点,提出了利用防窜剂加增效剂体系改善超稠油蒸汽吞吐后期效果的采油工艺技术。现场试验结果表明,注蒸汽添加防窜增效体系的工艺技术能够明显提高蒸汽吞吐井的周期产液量、周期产油量以及油气比。该项技术用于改善超稠油蒸汽吞吐后期效果在技术上和经济上都是可行的。Aimed at the characteristics of high huff- puff order of turns and the bad huff - puff effect of superheavy oil wells in Liaohe Oilfield, an oil recovery technology for improving steam huff - puff effect of superheavy oil by using fleeing proof agent and intensifier system was proposed. The field test results showed that the oil recovery technology could obviously raise periodic mass production, periodic oil production and oil/steam ratio for steam huff- puff of superheavy oil by addition of fleeing proof agent and intensifier system. This technology was feasible for improving steam huff - puff effect of superheavy oil technologically and economically as well.
