Определение фильтрационных характеристик при вытеснении маловязких нефтей водой
КОЗЛОВ Н.Ф. — 1998 г.
Modelling experiments has been conducted on oil displacement with water with their viscosities correlation being very close to that under formation conditions. It is shown, that initially under low pressure difference displacement occurs in high permeability zones, and after water reaches zone of drainage where pressure difference increases - in low permeability zones, thus, D5 formation goes to water in the most permeable zones. Calculations have been conducted for displacement process in two-layered formation considering obtained relative permeability values for oil and water, utilizing SUTRA softwear, showing agreeable similarity between calculated and experimental results.

Особенности освоения низкопроницаемых глинистых коллекторов нефти в условиях шельфа Вьетнама
КАЩАВЦЕВ В.Е., ФАТКУЛЛИН А.А., ХАВКИН А.Я. — 1998 г.
The study concerns the problem of oil production rate increase from the Low Oligocene reservoir of the largest Vietnam offshore White Tiger field as an example of low permeable clay reservoir. The features of waterflood performance and bottom-hole zone permeability changes in dependence with mineralization of reservoir, injected and drilling mud make-up waters have been described. It has been found that physicochemical stimulation methods with surfactants, alkali and high temperature polymers should be used for oil production increase. The software has been developed for calculation of such type reservoir development programs.
