Embodiment 1
[0037] A water-based wax remover for oil wells, consisting of the following components by weight percentage: 18% mixed surfactant, 2% composite dispersant, 9% alcohol ether co-solvent, 0.5% hydroxyethylene diphosphonic acid, 0.3 % disodium hydrogen phosphate, 0.3% sodium hexametaphosphate, 1% stabilizer, and the rest is composite magnetized water;
[0038] Among them, the mixed surfactant is composed of sodium oleoyloxyethanesulfonate, carbon fatty alcohol polyoxyethylene ether, octylphenol polyoxyethylene ether, and glycerol in a mass ratio of 4:2:1:1. The mixed surfactant prepared by the above ratio can greatly improve the wax removal and anti-wax effect. Mixing, the components of the mixed surfactant are stable and uniform, which is significantly better than that of a single surfactant. The combination of sodium oleoyloxyethanesulfonate, carbon fatty alcohol polyoxyethylene ether, and octylphenol polyoxyethylene ether can reduce each other. Loss in wax removal and anti-wax...
Embodiment 2
[0049] A water-based wax remover for oil wells, consisting of the following components by weight percentage: 21% mixed surfactant, 4% composite dispersant, 11% alcohol ether co-solvent, 1.2% hydroxyethylene diphosphonic acid, 0.4 % disodium hydrogen phosphate, 0.4% sodium hexametaphosphate, 2% stabilizer, and the balance is composite magnetized water;
[0050] Among them, the mixed surfactant is composed of sodium oleoyloxyethanesulfonate, carbon fatty alcohol polyoxyethylene ether, octylphenol polyoxyethylene ether, and glycerol in a mass ratio of 4:2:1:1. The mixed surfactant prepared by the above ratio can greatly improve the wax removal and anti-wax effect. Mixing, the components of the mixed surfactant are stable and uniform, which is significantly better than that of a single surfactant. The combination of sodium oleoyloxyethanesulfonate, carbon fatty alcohol polyoxyethylene ether, and octylphenol polyoxyethylene ether can reduce each other. Loss in wax removal and anti...
Embodiment 3
[0061] A water-based wax remover for oil wells, consisting of the following components by weight percentage: 25% mixed surfactant, 7% composite dispersant, 12% alcohol ether co-solvent, 1.5% hydroxyethylene diphosphonic acid, 0.5% % disodium hydrogen phosphate, 0.5% sodium hexametaphosphate, 3% stabilizer, and the balance is composite magnetized water;
[0062] Among them, the mixed surfactant is composed of sodium oleoyloxyethanesulfonate, carbon fatty alcohol polyoxyethylene ether, octylphenol polyoxyethylene ether, and glycerol in a mass ratio of 4:2:1:1. The mixed surfactant prepared by the above ratio can greatly improve the wax removal and anti-wax effect.
