Research On Acidified System For The Volcanic Reservoir

How realizes gets a light from another light the precipice oil gas Buddhist scriptures Jinan use is the petroleum profession urgently needed solution crucial question effectively. The acidified transformation technology was considered that is enhances the volcanic rock oil gas pool to produce can one of most effective ways. In recent years, Daqing, the Xinjiang Karamay and so on domestic oil field has carried on the volcanic rock acidification attempt work, at present from generally speaking, in the acidified fluid chemical reaction mechanism, the sour crag liquid solid dynamic flowing simulation, research aspects and so on acidified special medium influencing factor also waits for thoroughly, but also has the massive work to do。This research by the Jilin oil fieldⅠThe kind (porosity≥5% I kind of reservoirs, porosity 3-5% II kind of reservoirs,≤3% III kind of reservoirs) including the CO2 volcanic rock reservoir oil deposit are the objects of study high, the system has carried out the volcanic rock oil gas pool acid liquor system research as well as the sour crag response microscopic analysis work thoroughly in the former foundation. Mainly includes the different acid liquor system to the core sample corrosion function research, the chemical additive in acid liquor system function research, CO2 to the acid liquor corrosion property influence research and so on indoor static state experimental study work, based on this and thoroughly did the core sample different acid liquor corrosion EMES appearance attribute analysis work, the acidified system core sample corrosion performance flowing simulator study, to cross linking the sour gel to make through work and so on system research。Through moved the static experiment and the core sample different acid liquor corrosion EMES appearance attribute analytical study has formed the crack compact oil gas pool's acidified system; Has developed under for the first time the hot conditions CO2 to the corrosion inhibitor inhibition effect influence research; The indoor realized the artificial crack simulation acidification to relieve the core sample mud injury the research.
