<p>The proposed invention relates to oil and gas industry, namely to the devices for carrying out a hydraulic fracturing with following well clean-up and can be used for carrying out the well remedial work for stimulation of a hydrocarbons inflow. Provides a significant saving of time and financial costs for execution of the hydraulic fracturing work package. The borehole configuration comprises a mounting on the tubings (1) from top to bottom a ejector pump (4) with a through channel, a packer (2) and a hole (10) for pumping up the hydraulic fracturing fluid. According to the invention the configuration contains an additional packer mounted on the tubings below the first packer, with the possibility of mounting the packers above and below the intended for the hydraulic fracturing an interval of formation, where the hole for pumping up the hydraulic fracturing fluid is a window made between the packers. The variant of the configuration is proposed where it contains a straddle packer, comprising an upper and lower packer units, mounted on the tubings with the possibility of mounting the packer units above and below the intended for the hydraulic fracturing the formation interval, where the hole for pumping up the hydraulic fracturing fluid is a window made between the packer units.</p> |
