Differentiation and grouping of complex-structured oil reservoirs in carbonate reservoirs in development management problems solving

Abstract

The article presents the developed algorithm and the results of carried out differentiation and grouping of oil deposits in the carbonate reservoirs of the Volga-Ural oil and gas province, both under development and out of exploration, according to geological parameters, the determination of which is possible at the stage of geological exploration. A method for selecting an analogue deposit, which has been in development for a long time has been worked out for a deposit coming out of exploration in order to use the experience of developing an analogue deposit in the conditions of a deposit being put into development. The comparison of the selected groups of objects by geological parameters is carried out, the characteristics of the features of each of them are given, the main differences in the geological structure are revealed. It has been established that the features of the geological structure of various groups of objects are mostly determined by their tectonic-stratigraphic confinement. Keywords: free-flow production; increase of differential pressure; field-scale experiment; well pattern; well interference; oil flow paths.

“…Одними из таких объектов являются низкопродуктивные залежи в карбонатных коллекторах нижнего карбона и верхнего девона восточного региона Волго-Уральской нефтегазоносной провинции. Объекты, находящиеся длительное время в разработке, были дифференцированы [42,43] в 8 групп, в пределах которых объекты близки по особенностям геологического строения (табл. 1).…”

Oil flooding in carbonate reservoirs management

“…В работах [29][30][31][32][33] , на основании использования данных потокометрических исследований нагнетательных скважин, установлено, что с увеличением перфорированной толщины пласта коэффициент охвата пласта закачкой снижается. Этот факт объясняется ростом неоднородных включений при увеличении мощности продуктивного пласта.…”
