Application of salt-resisitant comb-shaped polymers in polymer flooding

Zhenquan Li

Abstract

This paper reported the application of salt-resistant comb-shaped polymer(KYPAM)in polymer follding with comparison to MO-4000 under the conditions of Shengli oilfield job site testing.When the KYPAM dosage is 53% less than MO-4000,water content of oil well is reduced by 1.7%,and the daily oil output increase is 44.9%.It is concluded that KYPAM has very good properties for use in Shengli oilfield EOR (enhanced oil recovery)application in the future.
