摘要 为证实弱凝胶与微生物调驱联作技术的作用效果,利用大直径长管填砂岩心模型,进行了弱凝胶调驱剂与微生物实施调驱联作的可行性和效果研究。试验表明,调驱联作技术明显提高了岩心采收率,为三次采油技术的完善提供了新方法。 Because of investment limiting,the application of tertiary oil recovery technique is limited.It is a new task under the recent oilfield exploitation situation to study how to gain the maximum profits on lower investment of tertiary oil recovery technique.Therefore,since the reservoir substances constantly changes,the factors affecting exploitation in late period of oilfield exploitation become complex.By displacement experiments of long cores,we have studied the feasibility and the effect of weak gel enhanced oil recovery cooperated microbial enhanced oil recovery technique.The study shows,this technique could gain advantages and avoid shortcomings.So we can achieve the maximum interests and it will also provide us a new way to perfect tertiary oil recovery technique.
