三相泡沫体系堵水效果及影响因素实验研究

Abstract

Abstract:

As a new type of foam stabilizing material, nano-particles can significantly improve the stability of foam. The research and application of nano-particles have been paid much attention by petroleum researchers. Considering the demand of water plugging technology in Bohai Oilfield, and guided by the theory of physical chemistry, polymer materials and reservoir engineering, we studied the evaluation of basic performance and the physical simulation of water plugging effect of nano-particle nitrogen foam system according to the geological characteristics and fluids of typical reservoirs in Bohai by technical means such as instrument detection, chemical analysis and physical simulation. The results showed that when the concentration of foaming agent（PO-FASD） and stabilizer（SiO₂ nano-particle AEROSIL380） were about 0.3 %, the foaming agent and foam stabilizer could form the three phase foam system with nitrogen in excellent performance. With the increase of the reservoir permeability gradation, the effect of water flooding development got worse, and the effect of foam plugging and increasing oil increased. While with the increase of the water flooding recovery, the effects of foam plugging and oil increasing effect were improved. However, if the viscosity of crude oil increased, the effects of foam plugging and oil increasing effect would get worse. Thus, we could find that the three-phase foam system has good plugging and liquid flow steering ability, especially suitable for high water cut reservoir high permeability layer water plugging.

Key words: Bohai oilfield, three phase foam, nano-particles, water plugging, physical simulation
