高浓度聚合物驱油技术是一种新型的大幅度提高原油采收率的方法,由于浓度高,溶液的粘弹性增大,可在提高波及效率的同时提高驱油效率,从而提高原油最终采收率。目前在机理上已有了很深的认识,在现场应用上也取得成功。本文通过对试验区不同阶段进行的调整措施进行分析,得出了不同阶段的调整方法,为以后工业化区块大规模推广提供参考。
High concentration polymer flooding technology is a new method for greatly increasing oil recovery. Due to the high concentration and the increased viscoelasticity of the solution, the flooding efficiency can be improved and the flooding efficiency can be improved at the same time, so that the final oil recovery Yield. At present the mechanism has been very deep understanding of the application in the field also achieved success. Through the analysis of the adjustment measures in different stages of the pilot area, this paper obtained the adjustment methods in different stages and provided references for the large-scale popularization of the industrialized blocks in the future.
