PROCESS OF DEVELOPMENT OF INHOMOGENEOUS OIL AND GAS BEDS Russian patent published in 2003 - IPC

FIELD: oil and gas industry. SUBSTANCE: process is related to use of structure- forming and intensifying compositions for control over coverage of bed by flooding with pumping of compositions through injection wells and to water insulation operations in oil and gas wells and to repair-insulation operations in injection and operating wells. According to said process bed is consistently treated by structure-forming and intensifying compositions to equalize permeable inhomogeneity. This provides for maximum decrease of coefficient of vertical permeability of bed with minimal reduction of average permeability of bed. Coefficient Dikster-Parson of vertical permeable inhomogeneity calculated by analytical formula on basis of core material or logging examinations is used in the capacity of criterion of permeable inhomogeneity. After complex action on bed with use of compositions permeability of each interlayer comprising bed is also computed by analytical formula. EFFECT: increased efficiency of technology of complex action on bed inhomogeneous by permeability when it is consistently treated by structure-forming and intensifying compositions. 1 cl, 2 dwg
