Annotation:

The article describes the method for optimization of hydraulic fracturing technology by elimination of the stage of mini-hydraulic fracturing technology in the fields of the Perm territory. The stages of hydraulic fracturing technology implementation are described and the main defined technological parameters are presented. The initiative to eliminate the stage of mini-hydraulic fracturing is mainly aimed at reducing the cost of hydraulic fracturing operations, while there are concomitant positive factors: a decrease of a reservoir clogging due to a decrease of the volume of injected chemical reagents; a reduction of the time required for conducting a hydraulic fracturing operation due to the exclusion of some preparatory work related to the mixing fluid delivery and heating, gel preparation, injection of a mini-fracturing stage, recording of the pressure drop curve and analysis of the mini-fracturing stage. The results of hydraulic fracturing conducted in the fields of the Perm territory are examined in detail, where the optimization of the technology has led to a reduction in the time and cost of work while ensuring increased technological efficiency and the absence of deviations during the use of hydraulic fracturing as well as allowed obtaining an additional effect like extra oil production.
