Description
Technical field
A kind of low-temperature reservoir air foam flooding shaft oxygen consumption experimental facilities.
Technical field
The utility model relates to air foam flooding shaft oxygen consumption experimental facilities field, oil field, and particularly a kind of low temperature low permeability oil field evaluates the experimental facilities of air foam flooding shaft Security and feasibility.
Background technology
Air injection improve recovery ratio be a kind of air compressor that utilizes by the new technology of air Injection oil reservoir, have that source of the gas enriches, cost is low, by the advantage of region and environment restriction.Air injection not only has the effect of general gas injection, and has other effect of oxidation generation.In producing in the past, air injection is in fact is mostly carry out combustion in situ exploitation for heavy crude reservoir, in recent years, crude oil price remains high, light oil reservoirs air injection improves recovery efficiency technique and is subject to most attention, air-injected low-temperature oxidation can significantly improve the oil production of light oil reservoirs, and oil recovery factor can be made to improve 7%-15%.Thick oil filling air burns oil reservoir development, and by shaft bottom manual firing, enter high-temperature oxydation reaction, reservoir temperature reaches 500-600 DEG C.And LOW PERMEABILITY RESERVOIR is light oil reservoir substantially, air injection exploitation does not have shaft bottom manual firing, the temperature that light oil oxidation liberates heat can reach in oil reservoir is lower, be commonly referred to as low-temperature oxidation, low-temperature oxidation reaction is that light oil reservoirs air injection improves one of mechanism of recovery ratio, oxygen is consumed completely inner on stratum, and it is dangerous to be unlikely to oxygen breakthrough appearance.Generally believe that the low-temperature oxidation limiting temperature of best oil product is also more than 60-80 DEG C, and low permeability oil field part oil district, North Shaanxi Province of China area reservoir temperature is on the low side, only less than 30 DEG C, is unfavorable for low-temperature oxidation, namely the probability of oil reservoir inside generation low-temperature oxidation is very micro-.In such cases, the oxygen sub-fraction injecting stratum is consumed by low-temperature oxidation reaction, and major part by country rock, formation water and crude oil consume, remaining oxygen will form Combination explosion gas with the light hydrocarbon component in stratum, when the concentration of gaseous mixture reaches within explosive range, accident of will blasting under certain condition.In order to prevent the generation of explosion accident, must by experiment simulated air inject to occur behind stratum low-temperature oxidation, by country rock, formation water and crude oil the amount of oxygen that consumes, thus the content controlling oxygen is below safety content of oxygen.And there is no the special experimental facilities for the experiment of low-temperature reservoir air foam flooding shaft oxygen consumption at present.
