| titleOfInvention | It is a kind of to note strong pressure-air, oxygen-enriched flooding method to deep buried hill reservoir |
| abstract | The present invention provide it is a kind of noting strong pressure-air, oxygen-enriched flooding method to deep buried hill reservoir, include the following steps：High-pressure gas injection well completion is carried out to gas injection well first, injects 0.05~0.15PV initiators after completion into gas injection well, initiator uses sodium sarcosinate and mannitol；Strong high-pressure gas injection is carried out, injects 3~50,000 mark side's air to stratum；It is denitrogenated by air, isolates the oxygen-rich mixture of oxygen quality percentage 50~70%, oxygen-rich mixture is injected into oil reservoir；Carry out strong high-pressure gas injection；After stratum, which cracks, stablizes, increases gas injection rate and carry out strong high-pressure gas injection.This method cracks the crude oil of script colloid, heavy under formation temperature effect through Strong oxdiative, greatly improves rate of oil production and recovery ratio that follow-up air drives, reduces the oxidative cracking reaction time, realize quick oxicracking, improve the service efficiency of gas. |
