| 摘 要： | 聚合物本身作为一种重要的驱油用剂,具有驱油及示踪双重作用,根据油井见聚与见效关系,可以反映油井见效机理,利用聚合法聚类分析,以油井见聚时间、见效时间、含水率降低幅度和见效有效期为样本因子进行聚类,在分类基础上统计各类储层参数及非均质情况,结果表明大庆油田表外储层,最佳聚驱选井静态资料范围渗透率450mD左右,洛仑兹系数0.3以及突进系数为2左右为最佳聚驱油藏,该结果为聚驱后进一步提高采收率以及今后聚合物驱的选区提供一定的指导作用。 |

| Abstract: | As an important oil displacement agent,polymer have the two role of flooding and tracer.the relationship between polymer breaking time and the starting response time,the mechanism of polymer flooding can be showed.Utilising clustering analysis method,using polymer breaking time,starting response time,scope of water cut decline and term of validity as samples to clustering,on the base of classification,statistics various reservoir parameters and aeolotropism level.The results show that the optimum permeability for polymer flooding of the useless reservoir of Daqing oilfield is 450mD,coefficient of Lorentz is 0.3 and coefficient of rush is 2.The results provide a definite guide role for enhanced oil recovery after polymer flooding and block chosing of polymer flooding. |
