Prof. V.N. Schelkachev at first made theory of elastic regime for oil-gas bedding systems on based the investigations the plural outage wells in Grozny’s oil field at war conditions in 1942 ye. After putting in operation the wells (for increase it amount there no having finance and physical resources) have more dynamic levels than before and start to more production. This are explained with elastic reaction of porosity-permeability medium and saturation liquid.
Analogy conditions were being in Russian oil industry at beginning 90’s last century: there were not turn-over capitals to putting in operation outage wells; its amount were growth. Average period downtime of one well set up 5-7 years. Main these wells put in operation after downtime.
In article were made analyses of hydrodynamics effect from long downtime of many produce wells at main object development Arlanskoye oil field – terrigenous low carbonic thick series. Criterions on representative wells are work out and analyses made only for its. Representative wells make up 24.0% from total quantity of outage ones.
In result objective geology & petroleum date confirmed main statement of theory elastic regime: elastic energy content growth up; in conformity with present process growth seam pressure and hydrodynamic conditions support the increase of summary producing of oil from terrigenous low carbonic thick series and Arlanskoye oil field common.
