摘要(Abstract)：

针对安塞侯市低渗裂缝性油藏水驱开发中平面与纵向矛盾大、水驱效率低的问题,开展了聚合物微球与微生物调驱联作技术室内评价及现场试验。物理模型实验结果显示,调驱联作技术能明显提高岩心采收率。现场试验表明,聚合物微球体系与微生物配伍性良好。矿场试验后,注水井压力上升,吸水指数下降,压降指数增大,试验区原油性质改善,流动性增强,起到控水增油作用,有效期达6个月以上。联作技术比单一提高采收率技术更具优势,可有效调整吸水剖面和提高原油采收率。
In the light of the problems of the horizontal and vertical serious contradictions and lower swept efficiency for the waterflooded low-permeability fractured oil reservoirs in Houshi Block of Ansai Oilfield,the indoor evaluation and field test were conducted for the profile control and flooding by the polymer microsphere and microbes. The experimental results of the physical simulation show that the integrating technique can obviously enhance the recovery of the cores. The field test indicates that there are much better compatibilities between the polymer microsphere and microbes. After the field application,the pressures of the water injectors were increased,their water injectivity indexes were reduced,the pressure drop coefficients were enhanced,the properties of the crude oil in the test area were improved,the mobility was strengthened,so the actions of water control and oil increment were well displayed,the validity could reach more than six months. The integrating technique possesses more advantages than the individual EOR technique; it can effectively adjust the water injection profiles and enhance the oil recovery.
