Abstract:

This article has obtained the conclusion that oil displacement efficiency changes as wettability of the long-term water-injection reservoir changes into water affinity by applying the technological means of indoor high temperature and high pressure physical analogue experiment，oil deposit numerical simulation and so on.This research result will offer some guidance and reference to the adjustment of the developing plan in high water oil-field development.

Key words: wettability alteration, water flood multiples, oil displacement efficiency, displacement degree, fault block oil reservoir
