Sobol V. Features of flushing fluid penetration zone formation based on well-logging methods and improvement of technologies to increase the hydrocarbon inflow.

The dissertation is devoted to solving a relevant problem – study of the formation of flushing fluid filtrate penetration zone in reservoirs based on geophysical research data, methodical approaches to estimation of depth of its formation and connection between the penetration zone and geological and reservoir characteristics of rocks, improvement of the method for permeability coefficient determination according to geophysical research data for reservoirs of granular type. The study and modeling of the influence of different factors on parameters of the perforation channel have been conducted during hydro-sandblast perforation in order to overcome adverse effects of large penetration zones in the near-wellbore part of the reservoir. The hydro-sandblast perforator’s construction has been improved, and bench tests of the developed perforator have been performed.
