Physicochemical Properties and Oil Displacement Efficiency of Gemini Surfactant ASP Flooding
摘要
Abstract
The anionic Gemini surfactant Sodium dioleoylamino cystine (SDOLC) was synthesized by one-step reaction of sodium cystine and oleoyl chloride .The reducing oil/water interfacial tension properties and viscoelastic properties of Gemini/HPAM/alkali mixed system were investigated by Texas-500C spinning drop interface tensiometer and MCR301 rheometer ,and the oil displacement efficiency in homogeneous and heterogeneous cores were evaluated . It was found that the minimum dynamic interfacial tension magnitude between Daqing crude oil and Gemini surfactant/alkali mixed solution is not affected with the addition of HPAM ,but the viscosities increased .Overall considering the interfacial tension and viscosity ,mixed solution including mass fraction of 0 .18% HPAM ,0 .1% SDOLC ,0 .15% NaOH and 0 .06% HEDP · Na4 was chose as Gemini surfactant ASP flooding system .The viscosity of this system was 44 mPa · s and oil/water interfacial tension was 2 .4 × 10-2 mN/m .Homogeneous and heterogeneous cores were water flooded until 98% water cut ,and then were treated by 0 .6 PV Gemini surfactant ASP slug followed by water flooding to give an enhanced oil recovery of 26 .11% and 22 .25% ,respectively .关键词
