Improving oil recovery efficiency.
Improve fluid fluidity: foaming agent can form stable foam, which can reduce fluid viscosity, improve fluid fluidity, and make oil easier to be pumped to the ground.
Increase oil displacement efficiency: in foam oil displacement technology, foaming agent is mixed with water and gas to form foam. These foam can block high permeability 1ayers, force crude oil to flow through low permeability layers, thus improving oil displacement efficiency.
It can foaming with air,nitrogen and carbon dioxide.High temperature and salt resistance,good compatibility
