摘要
针对我国近海稠油开发中存在的一次及二次原油采收率低、油水粘度差大、易水突、产层多、储层非均质性严重、生产压差大、油层内微粒运移严重、胶质、沥青质等有积垢沉淀物在井筒附近形成严重堵塞等问题,提出了采用微生物与CO2复合驱的方法。分别归纳了注CO2开发稠油与微生物开发稠油的方式及应用情况;分析了CO2-微生物复合驱开发稠油的可行性;提出了CO2-微生物复合驱在开发稠油时需解决的问题。在稠油的开采与提高采收率方面具有重要的应用价值和推广意义。
Aimed at such problems in heavy oil production near shore as low primary and secondary recovery efficiency , high viscosity difference, easy water breakthrough, many producing pays, serious reservoir heterogeneity, high producing pressure difference, severe fine particle migration in the reservoir, severe near-bore plugging caused by organic settlement of colloid and asphalt, the new method of microorganism-CO2 compound flooding is suggested. The article separately summarizes the heavy oil development ways and application state of microorganism injection and CO2 flooding, analyzes the feasibility that microorganism-CO2 compound flooding develops heavy oil fields and then puts forward the problems that need being solved when using the new method. The method is of very important value and popularization in the development and enhanced oil recovery of heavy oil.
