Abstract

The invention discloses a nano active material. The nano active material is obtained by carrying out surface modification on organic modified montmorillonite by adopting maleic acid and a small molecular surfactant monomer. On one hand, modified montmorillonite and a traditional polymer monomer are copolymerized to form a net structure by taking a nucleation effect of a nano material as theoretical guidance, inward curling of a molecular structure can be inhibited under high-temperature and high-salt oil reservoir conditions, a polymer molecular chain keeps an intramolecular/intermolecular specific molecular structure, and foaming and liquid carrying performance reduction caused by degradation and curling of polymer molecular chains due to temperature and mineralization degree are reduced. On the other hand, by introducing a salt-resistant monomer, the salt resistance of the foam scrubbing agent under a hypersalinity condition is improved. The foam scrubbing agent developed by the invention is convenient in raw material source, relatively simple in preparation process, low in cost and low in energy consumption, and compared with a conventional foam scrubbing agent, the foam scrubbing agent is high in foam scrubbing temperature, rapid in foaming, large in foaming amount and long in foam stabilizing time.

Description

technical field [0001] The application relates to a nano active material and its preparation method and application, belonging to the technical field of nano materials. Background technique [0002] In the middle and late stages of natural gas well development, formation energy decreases, and formation water enters the near-wellbore area or wellbore with natural gas flow, and accumulates there, resulting in water flooding and a decrease in gas well production. At present, in order to solve the problem that the production of gas wells is affected by formation water, the foam drainage gas recovery technology is adopted, that is, the foam drainage agent is injected into the wellbore. Aqueous foam that is brought to the surface by air flow, reducing fluid accumulation in the wellbore. In the natural gas exploitation technology, the foam row technology has attracted more and more attention due to its advantages of convenient construction, simple equipment, low cost, wide range o...
