Embodiment 1
[0022] (1) Take 100 mL of crude oil from heavy oil field C and heat it in a water bath at 75°C, add 8 mg of demulsifier DP32, shake it manually and mix well.
[0023] (2) Take 1.5 mg of a mixed solution composed of n-hexane, cyclohexanol and diethylene glycol methyl ether, wherein the mass ratio of each component is n-hexane: cyclohexanol: diethylene glycol methyl ether=1:2:4 , manual shaking to mix evenly. According to the industry standard SY / T5281-2000, the performance of demulsification and dehydration was evaluated, and the dehydration rate at 30 minutes and 60 minutes, the oil content of the dewatered sewage and the oil-water interface were recorded respectively.
Embodiment 2
[0025] (1) Take 100 mL of crude oil from heavy oil field C and heat it in a water bath at 75°C, add 6 mg of demulsifier DP61, shake and mix by hand.
[0026] (2) Get 4 mg of a mixed solution composed of n-pentane, isohexyl alcohol and diethylene glycol butyl ether, wherein the mass ratio of each component is n-pentane: isohexanol: diethylene glycol butyl ether=1:2:6 , manual shaking to mix evenly. According to the industry standard SY / T5281-2000, the performance of demulsification and dehydration was evaluated, and the dehydration rate at 30 minutes and 60 minutes, the oil content of the dewatered sewage and the oil-water interface were recorded respectively.
Embodiment 3
[0028] (1) Take 100mL of crude oil from the polymer injection oilfield P and heat it in a water bath at 65°C, add 15mg of demulsifier DP32, shake it manually and mix it evenly.
[0029] (2) Take 3 mg of a mixed solution composed of n-butane, 1,2-propylene glycol, and diethylene glycol dimethyl ether, wherein the mass ratio of each component is n-butane: 1,2-propylene glycol: diethylene glycol two Methyl ether = 1:3:8, shake manually to mix well. According to the industry standard SY / T5281-2000, the performance of demulsification and dehydration was evaluated, and the dehydration rate at 30 minutes and 60 minutes, the oil content of the dewatered sewage and the oil-water interface were recorded respectively.
