Abstract

The invention provides a nanometer surface active agent for oil exploitation and method for making same, the surface active agent is prepared from nano material, 4A-zeolite, sodium carbonate, sodium sulfate, sodium silicate, polyoxythylene fatty alcohol ether sodium sulfate, dodecylbenzene sulfonic acid sodium, dodecylbenzene sulfonic acid and aromatic hydrocarbon dissolvent through mixing, heating, and stabilizing.

Description

Technical field: [0001] The invention relates to an active agent for oil exploitation and a preparation method thereof, which belongs to the category of oil field chemical additives. technical background: [0002] In the process of oil recovery and production in oil fields, in order to maintain the normal production of oil wells and prevent and remove paraffin deposits on the tubing wall, anti-wax agents are widely used; in order to relieve formation blockages and increase crude oil production, oil layer plugging removers are often used; in order to reduce viscous Viscosity reducers are widely used in the development process of heavy oil; in order to improve the water recovery rate of heavy oil thermal recovery wells, thermal recovery wells often use drainage aids before steam injection. The basic mechanism of action of these chemical additives is to change the surface effect of crude oil, pipe wall and oil layer respectively. At present, due to the lack of multi-functional...
