Alkali-surfactant-polymer flooding experiment in GT block of Daqing oil field
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 4
Abstract
GT block at present, injection-production well pattern and water injection mode has basically met the needs of oil field development. In order to study the suitable surfactant flooding system of domestic carboxylate for ASP flooding in Daqing oil field, for the first time, in GT block we carry out domestic oleic acid carboxylate surfactant applied to field experiment of asp flooding. The indoor experiment and field test show that, test obtained the effect that oil is increased and water precipitation is reduced. In addition, great changes have taken place in ion of produced fluid. And emulsification happened, but emulsification extent without added. This experiment is the first time to apply oleic acid surfactant in Daqing oil field. Therefore the result and analysis produce a positive effect on alkali-surfactant-polymer flooding in Daqing oil field. Keywords: GT block, Daqing oil field, surfactant
