Description of Compound Ionic Demulsifier for Oil Recovery

1. Overview and characteristics.
With the increase of crude oil, heavy oil and complex heavy oil production and frequent oil flooding and well washing operations in oil field development, the crude oil content in sewage increases. After the traditional sewage treatment process settles, organic and inorganic treatment agents are added at one time, and the crude oil obtained contains many suspended impurities, and the low quality and low price are not cost-effective. The agent is a combination of cationic polymer and block resin functional group compound ammonium salt. The average molecular weight is 600 to 4 million, which can be added before the sedimentation tank to promote oil-water separation. The agent is added in the post-treatment process, and the high-quality crude oil is floated, and then the sewage is treated to remove impurities. The effect is good. This agent is especially suitable for conventional crude oil demulsification; tertiary oil recovery demulsification and other anionic active agent flooding block sewage treatment.
