Abstract

The invention belongs to the technical field of oil field wastewater treatment, and specifically relates to a degreaser used for treating ternary compound flooding produced water in an oil field. The degreaser is prepared by compounding an adamantine mono-quaternary cationic surface active agent, sodium percarbonate, tallow soap, sodium ethylene diamine tetracetate and water, wherein the adamantine mono-quaternary cationic surface active agent is a molecule with a long carbon chain alkyl non-polar group and an adamantyl polar group. The degreaser has the characteristics of simple preparation process, low cost, strong temperature resistance and salt tolerance, and excellent degreasing effect; the degreaser can resist the temperature up to 230 DEG C, the resistance degree of mineralization is 230000mg / L, and the oil removal rate is more than 97%, and is improved by more than 50% compared with an existing agent. Therefore, the degreaser is widely applied in the degreasing process of the ternary compound flooding produced water.

Description

technical field [0001] The invention relates to a degreasing agent for oil field sewage treatment, in particular to an oil degreasing agent for oil field three-element compound flooding production sewage treatment. Background technique [0002] With the continuous development of oilfields and the continuous development of oil recovery technology, it has experienced primary, secondary, and tertiary oil recovery. Some oil fields in my country have entered the stage of tertiary oil recovery. Common tertiary oil recovery methods include polymer flooding, ASP flooding, binary flooding (alkali-polymer flooding, ie AP flooding), alkali flooding, foam composite flooding, etc. The composite flooding recovery technology is the most typical. Relevant studies have shown that ASP flooding can significantly increase oil recovery and has broad application prospects. However, because the produced water of ASP flooding contains a large amount of polyacrylamide, surfactant and alkali, the p...
