Abstract
Recently, there has been a tendency in the Russian Federation to reduce the design values of oil recovery, the main parameter characterizing the rationality of field development. In many ways, the decrease in question is due to the development of the most productive deposits discovered back in Soviet times. To maintain production levels in mature fields, it is necessary to apply various methods of increasing oil recovery (MIOR). According to many experts, one of the most effective ways to increase oil recovery are methods aimed at increasing the reservoir coverage ratio and displacement coefficient by pumping various chemical compositions into the productive reservoir. Thus, when using various physico-chemical methods of enhanced oil recovery (PCMOR), it is necessary to conduct preliminary assessments of their effectiveness. Due to the comprehensive analysis of field data on several fields in Western Siberia, the main geological and technological parameters that most affect the effectiveness of the measures are highlighted in the work. Based on the selected characteristics, using geological and statistical modeling, a methodology for predicting the specific effect of PCMOR MIOR treatments has been developed.
