Definitions
- the present invention relates to a surfactant composition.
- the present invention relates to a surfactant composition useful for tertiary oil recovery, a process for its manufacture and its use in tertiary eucalyptus oil. Background technique
- the tertiary oil recovery technology is an effective method to increase the oil recovery rate.
- chemical flooding technology is a very important and large-scale implementation technology in tertiary oil recovery, including polymer flooding technology, surfactant flooding technology, alkaline water flooding technology, etc., as well as polymers, alkalis, and surfactants.
- Chemical flooding is the result of both physical and chemical interactions. The physical action utilizes the sweeping action of the displacement fluid, while the chemical action utilizes the microscopic oil displacement of the displacement fluid. The core of the chemical action is to reduce the interfacial tension between the displacement fluid and the crude oil.
- Surfactants have both oleophilic (hydrophobic) and hydrophilic (oleophobic) properties.
- the molecules When the surfactant is dissolved in water, the molecules are mainly distributed at the oil-water interface, which can significantly reduce the oil-water interfacial tension.
- the decrease in oil-water interfacial tension means that the surfactant system can overcome the cohesive force between crude oils and disperse large oil droplets into small oil droplets, thereby increasing the passage rate of crude oil flowing through the pore throat.
- the oil displacement effect of the surfactant is also manifested in the reversal of the wettability of the oleophilic rock surface, the emulsification of the crude oil, the increase of the surface charge density and the oil droplets, etc., which is the role of the surfactant in becoming a displacement fluid. The cause of the component of action.
- the prior art tertiary oil displacement fluid has many problems, mainly due to the poor interfacial activity of the surfactant component, resulting in low displacement efficiency of the displacement fluid produced therefrom, and at the same time due to the displacement fluid system. It is too complicated, so it is difficult to break the milk, and the sewage treatment is difficult. Because the displacement fluid contains inorganic alkali, it will cause damage to the formation and oil wells, causing corrosion equipment and pipelines, and the inorganic base will seriously reduce the polymer.
- Viscosity in order to achieve the desired viscosity, the concentration of the polymer is greatly increased, and the comprehensive cost of the oil recovery is increased;
- the active agent component has limited ability to resist high temperature, high salt and high salinity;
- the surfactant component has poor stability during compounding and is prone to precipitation.
