摘要
根据桥29断块部分岩心水驱油实验资料回归，得到评价其驱油效率和波及系数的适用经验公式。并从驱油效率、层内非均质、平面非均质、注采系统等方面，综合分析了影响复杂断块油藏水驱采收率的主要因素，提出了提高桥29断块水驱采收率的主要途径是提高平面波及系数。
This paper gains the experimental formulas adapting to Qiao 29 Block that oil displacement and sweep efficiency are estimated by using water-drive oil lahaator data of a part of rock in Qiao 29 Block have been proposed by a method of regession, analyses the main element affecting water-drive recovery efficiency of complex faultbfork reservior. In this paper, we bring forward that improving plane sweep efficiency is mostly approach to improve water-drive recovery efficiency according to systhetically of oil displacement, inter-zone internal heterogeneity, plane heterogeneity and injection-production system.
