Method for extracting a hydrocarbon oil and / or liquid nonaqueous phase (NAPL) of a subsoil

摘要

An extraction process of a hydrocarbon oil and / or a liquid non-aqueous phase (NAPL) of a subsurface, comprising: introducing into the ground a surfactant and / or a cosolvent to increase solubility and / or mobility of hydrocarbon oil and / or NAPLs and solubilize and / or desorbing the hydrocarbon oil and / or NAPLs; introducing into the ground a liquid oxidant which generates a gas phase; allow the oxidizer that generates a gas phase decomposes to form a gas phase; allowing the clean gas phase hydrocarbon oil hydrodynamically and / or NAPLs of soil particles subsurface; inducing hydrocarbon oil and / or NAPLs to flow towards an extraction well; extracting subsurface NAPL through extraction well.
