The company developed the carbon dioxide stimulation technology in 2003. After years of development, it has formed a full-process technical service system based on carbon dioxide (nitrogen) injection technology, supplemented by plugging adjustment technology before injection and anti-corrosion technology after injection.It can meet different needs in the application of carbon dioxide stimulation technology!
1. The main mechanism of C02 stimulation
Main oil production mechanism of C02 stimulation in typical reservoirs.
(1) Swell crude oil volume and increase oil phase separation flow
(2) The viscosity reduction effect of CO2 on crude oil improves the oil-water mobility ratio
(3) Foam Jamin Effect and Reduction of Water Phase Permeability during Reverse Drainage
