摘要 大庆油田聚合物驱井多年来仅能得到点测氧活化和电磁流量计给出的各层注入量,由于油田属于典型的非均质湖相沉积,层内纵向孔隙突变性导致点测资料无法反映出注入剖面的概念而影响治理方案的制定。2002年对电磁流量计进行技术改进,实现了连续点测的目的并在萨南聚驱井测井85井次,获得了注入剖面的认识和层内不同韵律段的注入量数据。列举了应用该资料认识地下状况所进行的区块和单井治理见到的效果,为连续测井方法的改进提供参考。 For many years, we have only acquired the separate injection volumes by points measurement and electromagnetic flowmeter logging in polymer flooding wells in Daqing oilfield. As Daqing oilfield is of the typical nonhomogeneous lacustrine facies deposition, the concept of injection profile is not easily obtained from the points logging data due to vertical porous discontinuity within the beds, eventually, affecting the oil displacement efficiency.So, Daqing Logging & Testing Services Company improved the electromagnetic flowmeter in 2002, and achieved the purposes of combining continuous logging with points measurement. This logging method has been applied 85 times in Sannan block, the result of which helps us further understand the injection profiles of the full wells and gain the data of intake volume of different rhythmic intervals in the beds. This paper illustrates how to use these data to value the effect of the polymer flooding in individual wells and blocks for improvements of the continuous electromagnetic flowmeter logging technology.
