Beschreibung
Zusammenfassung:	The invention discloses a crude oil desalting complex agent and a preparation method thereof. The crude oil desalting complex agent is prepared from the following components: (A) 30-80 percent of a maleic anhydride modified phenol-amine polyether compound, (B) 5-20 percent of a phase-transfer agent, (C) 10-30 percent of organic amine, (D) 2-15 percent of an asphalt colloidal dispersant, and (E) 2-20 percent of an auxiliary. The crude oil desalting complex agent has excellent demulsification desalting and dehydrating performance, and is especially suitable for desalting and dehydrating inferior crude oil with high colloid content and high asphaltene content.
