Abstract
The invention discloses a foam displacement agent which comprises the following process steps: S1, preparing the following raw materials in parts by weight: 5-75 parts of foaming agent paste, 1-35 parts of hydrogenperoxide, 0-5 parts of dimethicone, 0-20 parts of a foam stabilizing agent and 1-85 parts of water; putting the foaming agent paste, the hydrogenperoxide, the dimethicone and water ina stirrer to stir for 1-30 minutes as a speed of 1400-1800 revolutions / minute and obtaining a mixture A after uniform stirring; adding the mixture A in a foam generator and introducing air to obtain amixture B; mixing the mixture B and the foam stabilizing agent at a temperature of 40-55 DEG C to obtain the foam displacement agent. The foam displacement agent disclosed by the invention effectively improves the oil recovery ratio and is suitable for popularization.
Description
technical field [0001] The invention relates to the technical field, in particular to foam displacing agents. Background technique [0002] Foam is composed of gas, water, foaming agent and stabilizer, and sometimes other additives such as alkali, small moleculealcohol, solid particles, etc. Foam is a special dispersion system with gas as the dispersed phase and water as the continuous phase. A two-dimensional interface is separated from the thin liquid film. The three liquid films along the liquid film boundary always touch at an angle of 120°. The boundary where they touch each other is called the Plateau boundary. The application of foam in daily life, such as Shampoo, foam fire extinguisher. [0003] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as "industrial blood". There are oil reserves in some areas of the upper crust, and the main components are various alkanes, naphthenes, and aromatic hydrocarbons The oil-f...
