The structure of the oil-bearing strata and possibility of extracting oil from them

Abstract

It is important to study the structure of oil-bearing strata is. In many ways, the structure of the Earth’s layers affects the possibility of intensifying oil production. This is one of the urgent problems of the oil industry. Obviously, at various stages of oil field development, methods of intensifying oil production, depending on the structure of oil-bearing rocks and geological and physical characteristics have their own features, which are manifested when they are used in the field conditions. Determination of the oil recovery factor (ORF) causes great difficulty in the operational assessment of oil reserves. At the stage of initial assessment, this indicator is taken either by analogy, or approximately. In order to make this parameter more valid, the main factors influencing its formation were studied. The formula for calculating oil recovery factor takes into account three main coefficients: grids, displacement and waterflooding.
