Evaluation and Plugging Relief Technology of FYR Surfactant for Oil Well

Article Preview

Abstract:

When CaCL2 or CaBr2 solution is used to kill the well during the pump check process,the productivity of the oil well becomes unstable. The developed FRY surfactant that a nonionic polyether surfactant is used as main material and compounded with various anionic and zwitterionic surfactants could solve this problem. The results show it has excellent foamy characteristic and wettability, and can eliminate the alkali and water sensitization of stratum under acidic condition. The FRY surfactant has been successfully applied to the plugging relief of oil well. The synthesis, performance evaluation and field application of the FRY surfactant are introduced in the paper.
