摘要
针对辽河油田曙一区超稠油井吞吐轮次高、吞吐效果逐渐变差的特点,提出了超稠油三元复合吞吐采油工艺技术。通过11管人造岩心物理模拟驱替实验,开展了超稠油三元复合吞吐影响因素研究。实验结果表明:水蒸汽注入量、CO2注入量及表面活性剂使用质量分数对工艺效果均有影响。其研究结果对优化超稠油三元复合吞吐施工工艺及施工参数有重要的指导意义。
Because of the characteristics of high huff-puff order of turns and the bad huff-puff effect of superheavy oil wells in Shuyi Area of Liaohe Oilfield, this paper proposes an oil recovery technology for ternary combination huff-puff of superheavy oil. The technology is that oil is exploited with the form of huff-puff after injecting superheavy oil into wells with surfactant solution-CO2- steam. Influence factors of ternary combination huff-puff of superheavy oil by displacement experiment of physical simulation with 11 artificial cores are studied. The experiment results indicate that the quantity of steam and CO2 and the concentration of the surfactant solution have an influence in the technology effect, which provides an important guiding significance for optimizing the technology and parameters of ternary combination huff-puff of superheavy oil in Liaohe Oilfield.
