In situ combustion slug and steam driving combined type crude oil producing method

The invention discloses a method of oil pumping which adopts the combination of fire oil layer slug and steam drive and is applicable for the pumping of thick oil reservoir. After the steam soaking of the thick oil reservoir and before the pumping of the steam drive, the fire oil layer slug type pumping is performed; an ignition technology is adopted to ignite the oil layer to burn; an air compressor is used to inject air into the oil layer continuously from a center injection well; after 0.3 to 0.8 years of pumping, steam is injected into the oil layer through an injection well, and the steam drive type pumping is performed. The invention can generate the high temperature of 400 to 800 DEG C in the burning zone of the fire oil layer slug, which is in favor of the water stored in an individual well after the steam soaking to be vaporized as high-dryness steam; the temperature of the bottom of the injection well, and the dryness of the steam injected by the following steam drive are improved; the strata pressure is improved; larger producing pressure differential is achieved, which is in favor of improving the lifting rate of the oil well; moreover, the invention is in favor of shortening the low-production period at the beginning period of the steam drive and improving the developing effects of the steam drive and the recovery ratio of crude oil.
