Description
Technical field
The invention belongs to field use fields.More particularly to a kind of flammable closure work of emulsified asphalt method water logging fireflood oil reservoir
Skill.
Background technique
Fireflood is exactly using the heavy component in in-place oil as fuel, using air or oxygen rich gas as combustion-supporting
Agent takes the methods of spontaneous combustion and manual firing that reservoir temperature is made to reach crude oil burning point, and is continuously injected into combustion adjuvant, makes Crude Oil
Sustained combustion, combustion reaction generates a large amount of heat, heated oil reservoir, so that reservoir temperature rises to 600~700 DEG C, heavy component
It cracks at high temperature, the gas and water vapour of light oil, burning generation that gas, the heavy oil pyrolysis of injection generate are for driving
Crude oil is flowed to producing well, and is produced from producing well.
It is that air onlap is serious that combustion in situ, which recovers the oil there are a significant deficiency, and top development degree is big, when exploitation enters
Certain degree can cause has channeling, and especially own to develop oil reservoir, has channeling degree is bigger.
Current common ignition process causes fire floor position to employ unevenness, and the oil reservoir for being not suitable for fireflood generates coking waste,
Subsequent developable resource is greatly reduced, the heavy crude reservoir of steam soak exploitation is carried out especially for oneself, coking waste is asked
Topic is particularly acute.
Heavy oil wells envelope alter technical aspect mainly and have the particulate species such as traditional cements blocking agent, high temperature organogel, thermosetting resin,
The types such as gel particle blocking agent, foam class water shutoff agent.The wherein particulate species such as traditional cements blocking agent there are partial sizes big, non-selectivity,
The disadvantages of easily causing reservoir damage；High temperature organogel is on the high side；Thermosetting resin non-selectivity, curing rate are non-to temperature
It is often sensitive, poor controllability；Gel particle blocking agent can not inject earth formation deep；Foam class water shutoff agent plugging strength is too low, stratum is suitable
Answering property is poor.
