Abstract

The invention discloses a polyacrylamide nano composite material as well as a preparation method and application thereof. The polyacrylamide nano composite material is prepared from an acrylamide monomer and a nano material in situ, wherein the content of insoluble substances in the polyacrylamide nano composite material is less than or equal to 7%. The polyacrylamide nano composite material is resistant to high temperature and salt, a complexing agent does not need to be added in the preparation process, the cost is low, and the polyacrylamide nano composite material has a good application prospect as an oil displacement agent.

Description

technical field [0001] The application relates to a polyacrylamide nanocomposite material and its preparation method and application, belonging to the technical field of polymer material production. Background technique [0002] Petroleum, as "industrial blood", plays an irreplaceable role in national industrial development and national economy. With the sustained and steady growth of my country's national economy, the demand for oil continues to increase, but my country's per capita oil resources only account for 1 / 6 of the world's average level, and nearly 50% of crude oil needs to be imported every year to meet the national industry's demand for oil. need. [0003] Most of my country's developed oil fields have entered the middle and late stages of development, the contradiction between oil supply and demand has intensified, and energy reserves and market demand are urgently required to increase oil production and improve efficiency. However, the traditional enhanced oil...
