Abstract

The efficiency of oil production is influenced by various factors, the main of which are the reservoir properties of oil-bearing formations - porosity and permeability. Porosity determines the storage capacity and permeability determines the filtration ability. Reservoir properties generally depend on the type of reservoir, the particle size of the reservoir rock, the presence of clay particles, etc. However, the formation depth has the greatest influence on the reservoir properties. For all types of rocks, permeability and porosity decrease with the bedding depth increasing. The volume of the pore space and the permeability of rocks also depends on the effective pressure. In this work, on the example of the northern Perm Region oil fields, confined to layers of the same geological age, the influence of the layer's geological characteristics on their reservoir properties is assessed. When analyzing the reservoir properties of 40 oil layers, equations that describe the influence of the depth and effective pressure on the reservoir properties of oil layers were obtained. Analytical dependences of the influence of porosity on the permeability of rocks are also obtained.
