摘要
南泥湾油田偏侨区为典型的特低渗透岩性油藏,目前处于精细注水开发阶段,注采连通状况是影响油田注水开发水平的主要因素之一,对于实施精细注水开发的特低渗透油田注采连通研究尤为重要。本文立足单井组面向各小层引入注采井网劈分系数和注采连通劈分系数,重新建立了注采连通率的计算方法。该方法简单实用,实际应用结果与偏桥区实际开发特征一致。
Migrant overseas Chinese area in Nanniwan Oilfield is a typical ultra-low permeability lithologic reservoir. At present,it is in the stage of fine waterflooding development,and the connectivity between injection and production is one of the main factors affecting the level of oilfield waterflooding development. It is particularly important for the study of injection-production connectivity in ultra-low permeability oilfields with fine waterflooding development. Based on the introduction of injection?production well pattern splitting coefficient and injection-production connection splitting coefficient for each sub-layer of single well group,the calculation method of injection-production connection ratio is re-established in this paper. The method is simple and practical,and the practical application results are consistent with the actual development characteristics of Bianqiao District.
