Primary Study on EOR for High Temperature and Salinity Reservoirs in Tarim Basin

Abstract

Abstract: The exploitation status and existing issues are reviewed of Lunnan field and Tazhong-4 field in high water cut stage as major oil fields in Tarim basin. The primary research on EOR for reservoirs with high temperature, high salinity and high Ca and Mg ions are proposed. It is recognized that the key point should be focused on the remained oil distribution and new materials such as aqueous polymer gel, polymer resin, organic/inorganic composite material and inorganic material, which are suitable for profile control. And the nonionic-anionic surfactants, multi-polarization surfactants and special surfactants as oil displacement agents are technically and preliminarily studied in this paper.

Key words: Tarim oil field, tertiary oil recovery, EOR, high temperature, high salinity
