oil gas injection

In other countries, carbon dioxide injection technology is mainly used for the late high water reservoir, heterogeneous reservoir and is not suitable for thermal recovery of heavy oil expeller. Promotion of carbon dioxide flooding the major constraints is a natural resource of carbon dioxide, carbon dioxide and carbon dioxide to the conveying onrush production wells and wells machine for pellets corrosion problems, safety and environmental issues. To solve the above problem, a carbon dioxide injection for enhanced oil recovery technology, which is injected into the formation reaction solution under reservoir conditions make adequate response to release carbon dioxide gas, carbon dioxide dissolved in the crude oil among the lower oil viscosity, so as to achieve the purpose of enhanced oil recovery.
