# 国内外水驱油田油藏参数变化规律和特征研究Study on Reservoir Parameters Variation Rules and Characteristics of Waterflood Oilfield

Abstract: Study on reservoir parameters variation rules and characteristics provide fundament for develop-ment modes of optimizing remaining pay zone. This paper compares relative permeability calcula-tion methods domestic and overseas and studys influential factors of porosity and permeability var-iations during oilfield development, recognitions of this paper are concluded as follows: influential factors of porosity and permeability variations during oilfield development include factures conduc-tivity, pore scale and distribution, suspended solid of injected water, incompatibility of injected wa-ter and formation water, optimum injection rate, and rock types and resistance. According to the development status in domestic waterflood oilfields, when calculating relative permeability, foreign experience of focusing on correlation and match of measured data can be referred.
