Аннотация
The article presents the features of the geological structure of low-viscosity oil objects represented by carbonate reservoirs in the Fergana region of Uzbekistan, characterized by a wide range of changes in geological and physical factors and parameters of the implemented development systems. Based on the clarification of the parameters characterizing the structure of deposits, geo logical heterogeneity and reservoir properties of productive formations, as well as the results of developing objects in the late stage of operation. Using the method of multifactor correlation and regression analysis, a geological and statistical model was created that allows establishing the qualitative and quantitative influence of geological and technological factors on the oil recovery factor from objects in the Fergana region of Uzbekistan represented by carbonate rocks. It is shown that geological factors have an overwhelming influence on the oil recovery factor, and from technological factors, only the well grid density has a significant effect. The resulting geological and statistical model of the oil recovery factor is recommended for use in justifying geological and technical measures to improve the implemented development systems of objects.
