OIL POOL DEVELOPMENT METHOD Russian patent published in 1995 - IPC

FIELD: oil industry. SUBSTANCE: oil pool development method involves working agent injection by means of injection wells and withdrawal of oil by means of producing wells. For leveling the influx profile, the values of porosity and content of clay in the oil bed partings are determined, and the values are averaged. Perforation is performed with less numbers of perforation holes in partings showing greater porosity and lower content of clay, and more perforation holes are done in those partings that show lower porosity and higher content of clay than the average values. This is followed by selective interval-after-interval intensification treatments of the partings, and the same operations are performed in the producing wells. In the producing wells, prior to influx flow leveling, the watered partings are isolated and cut off. EFFECT: higher efficiency. 3 cl, 2 tbl
