Abstract
To ensure the rational development and selection of the most effective method of influencing the formation, it is important not only to identify filtration zones and determine their conductivity, but also to assess the activity of these pathways, fixing those areas (zones) that remain either weakly active or inactive under the existing reservoir pressure increase system (PPD). By itself, the presence of such sites causes inefficient maintenance of the energy state of the deposit and negatively affects the coverage ratio of oil reservoirs. However, in such areas of the reservoir that are not covered by flooding, there may be undeveloped oil reserves. According to the results of the work, it was found that the presence of inactive zones is determined by tracer studies of the deposit based on the low concentration of the tracer, its prolonged output and the correlation of the dynamics of its removal with the movement of the indicator in the filtration model; to identify the presence of the tracer and conduct a reliable interpretation, a spectrum survey is required to exclude the possibility of attributing natural fluctuations (noise) to the indicator signals; to increase the accuracy of tracer identification when removing the spectrum, it is recommended to adjust the pH value of the solution depending on the type of luminescent tracer used.
