Experimental Study of Foaming Agent Screening and Performance Evaluation of Nitrogen Foam Flooding in Daqing Oilfield

Abstract:

Through the laboratory experiment, the foaming properties of six kinds of foaming agent was evaluated comprehensively. Through the primary selection, foaming agent concentration selection and salt tolerance evaluation, HY-2 foaming agent was selected in follow-up experiments. The Liquid viscosity effect for foaming performance showed that there exists an optimal value of the liquid viscosity, corresponding to the concentration of foam stabilizing agent should not be less than 700mg/l. The impact of temperature on the performance of foaming agent was mainly on the foam stability, the higher the temperature, the stability of the bubble the worse. Due to the presence of crude oil, foaming volume and stability of the foam appeared a downward trend, the character of which is very advantageous to adjust fluidity difference between the layers of high permeable formation and low permeable formation.
