Experimental Study into the Processes Running in Hydraulic Packer upon Pipeless Water Lifting from Wells by Means of Electrical Submersible Pump

The work discusses the processes in hydraulic packer with ejector upon pipeless water lifting from wells, determination of engineering and technical parameters, verification of reliability and correction of theoretical backgrounds for the processes: fixation of hydraulic packer with electrical submersible pump in well, compression of hydraulic packer with well casing wall and pinching îf the packer detwisting mechanism in well; adjustment of major parameters of substantiated typical sizes of hydraulic packers with ejector during their experimental study.
