Examples
Embodiment 1
[0044] Example 1A-1C
[0045] In these examples we compare the individual efficacy of two betaine surfactants of the same type (A and B), and the efficacy of their mixed system (C). Betaine surfactant A is lauryl dimethyl betaine, and its lipophilic group has about 12 carbons. Betaine surfactant B is oleyl dimethyl betaine, and its lipophilic group has about 18 carbons. They belong to alkyl dimethyl betaine surfactants.
Embodiment 1A
[0047] Get lauryl dimethyl betaine (from U.S. Western Surfactants Research and Development Center (Western Surfactants Research and Development Center, USA, with 30% effective concentration, pH 6.0-7.0) 50 grams of deionized water 50 grams; beaker, and then stir evenly at room temperature with an electromagnetic stirrer. Adjust the pH to 7-8 with sodium hydroxide and acetic acid. The formed surfactant system is a uniform transparent liquid.
[0048] Crude oil: from oil fields in Northeast China, the crude oil presents high acidity and high aromatic components.
[0049] Test instrument: TX-500C interfacial tension.
[0050] Test conditions: (1) temperature 55 degrees Celsius; (2) salinity of reinjected water 4000 mg / L; (3) polymer: none; (4) dilution concentration of surfactant system: 0.05% (equivalent to lauryl Dimethyl betaine diluted 2000 times for use).
[0051] Test results: When the dilution concentration of the surfactant system is 0.05%, the measured oil-water interf...
Embodiment 1B
[0054] Get oleyl dimethyl betaine (from U.S. Western Surfactants Research and Development Center (Western Surfactants Research and Development Center, USA, with 30% effective concentration pH 6.0-7.0) 50 grams; 50 grams of deionized water; above respectively add a beaker, and then stir evenly at room temperature with an electromagnetic stirrer. Adjust the pH to 7-8 with sodium hydroxide and acetic acid. The formed surfactant system is a uniform transparent liquid.
[0055] Crude oil: from oil fields in Northeast China, the crude oil presents high acidity and high aromatic components.
[0056] Test instrument: TX-500C interfacial tension.
[0057] Test conditions: (1) temperature of 55 degrees Celsius; (2) reinjection water containing salinity of 4000 mg / L; (3) polymer: none; (4) dilution concentration of surfactant system: 0.05%.
[0058] Test results: When the dilution concentration of the surfactant system is 0.05%, the measured oil-water interfacial tension is 1.4 × 10 -3...
