Abstract:
     The chemical oil displacing agent may be used alone or recompounded with other surfactant with the recompound consisting of ligosulfonate modified by long carbon chain fatty acyl amide 2-50 %, other surfactant 2-50 %, and solubility agent 2-50 % other than water. The oil displacing agent with ligosulfonate modified by long carbon chain yacyl amide as main component constitutes stable, effective and cheap reinforced oil extracting system, ensures the very low interface tension in wide raw oil-water concentration range, and is favorable to the industrial application in reinforced oil extraction.
