Abstract

Active crude oil water plugging is a kind of water plugging technology without damage to the reservoir selectivity, and can achieve a good water plugging and enhancing oil production of purpose. Aiming at some problems existing in water blocking activity of crude oil research, research and solve some of the following issues: First, experimental study on the matching relationship between crude oil component and emulsifier, the activie crude oil and water plugging, selective plugging big channels for water effectively, the HLB value of 3.5~6.0 surfactant as emulsifier is better. Second, on the active crude adaptive control water and increase oil micro mechanism of active oil into the oil: crude oil in high water cut channel, in the fine pore throat due to shear the emulsion is formed, the formation of Jiamin action, the flow channel was blocked up with emulsified oil, water flow around the jam, into the oil flow channel, play the good water plugging and oil increase effect. In addition, the effects of ion composition, viscosity and sealing strength of petrophysical parameters on emulsion formation water influence viscosity and sealing strength of emulsion and injection time of water plugging effect is studied and the corresponding conclusion is drawn. These important conclusions through research have important guiding significance for the development of water flooding oilfield.
