孤岛中二区低张力泡沫驱油体系性能研究
Performance Research of Ultra-low Interfacial Tension Foam Flooding System of Gudao Second District
摘要
Abstract
In this paper, the reservoir of Gudao second district is a target area, and low interfacial tension foam flooding system to adapt to reservoir condition is developed. Through performance evaluation of foam, foam system interfacial properties and simulation test, foam performance, oil-water interfacial properties and block pressure in porous media, the ability to enhance oil recovery, different pressure changes and cut water changes are studied. Testing proves that the low interfacial tension foam flooding system has the characteristic of foam and surfactant. It can be on the double action of powerful washing and adjusting. Foam selective plugging and high apparent viscosity increase flooding systems affected area, and the activity of low interfacial tension foam system increase the displacement efficiency, and reduce the presence of residual oil, so that the foam system is more stable after injecting the foam system, the integrated oil recovery increased by 28%.关键词
