Abstract

The invention belongs to the technical field of oil field wastewater treatment, and particularly relates to an adamantine mono-quaternary ammonium salt cationic three compound combination flooding produced water oil remover, which is prepared from compounding an adamantine mono-quaternary ammonium salt cationic surface active agent, 4A zeolite, sodium carboxymethylcellulose, alcohol polyoxyethylene hydrogenated butter (11) ether and water. The adamantine mono-quaternary ammonium salt cationic surface active agent is a molecule with a long carbon chain alkyl non-polar group and an adamantyl polar group. The oil remover provided by the invention has the characteristics of simple preparation process, low cost, high temperature resistance and salt tolerance performances and good oil removing effect, the temperature resistance achieves 240 DEG C, the salinity tolerance degree achieves 240,000mg / L, and the oil removal rate reaches 97 percent or above and is improved by not less than 50 percent compared with an existing medicament. Therefore, the adamantine mono-quaternary ammonium salt cationic three compound combination flooding produced water oil remover provided by the invention can be applied in an oil removal process of three compound combination flooding produced water.

Description

technical field [0001] The invention relates to a degreasing agent for oil field sewage treatment, in particular to an adamantane monoquaternary ammonium salt cationic three-element compound flooding produced water degreasing agent. 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...
