ABSTRACT: 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 оf the packer detwisting mechanism in well; adjustment of major parameters of substantiated typical sizes of hydraulic packers with ejector during their experimental study. The work is based on patent reviews, theoretical considerations, calculations, procedural and experimental approaches.The work presents the results of performed experimental study of the processes in hydraulic packer with ejector upon pipeless water lifting from wells by means of electrical submersible pump: fixation and compression of hydraulic packer in well, pinching of detwisting mechanism. The following parameters are experimentally determined: coefficient of packer local resistances, friction coefficient of rubber-coated roller along steel pipe, required minimum excessive water pressure in packer for expansion of sealing ring, required force for packer shimming. Experimental study of the processes in hydraulic packer has confirmed reliability of the assumed mathematical backgrounds, they will be applied in development of their required typical sizes. Therefore, the positive experimental results of study of innovative patented hydraulic packer with ejector can be applied for marketing of devices with required typical sizes for electrical submersible pumps in order to implement efficient water lifting both for general purpose water supply and for melioration, thus reducing metal consumption by 2-3 times in comparison with the existing technology of water lifting (using pipes), as well as operational expenditures for assembling works, increasing operation lifetime of well casing, excluding water pollution and well clogging, improving power indices of pump facility.
