Mechanical packers
Mechanical packers are intended to be used for separation of the reservoir from the annular space or two reservoirs from one another.
Main distinguishing feature of our production packer from mass-produced one - is the ability to transfer the packer from transit to working condition and vice versa by vertical displacement of the flow column, whereon it is descended, instead of its rotating.
Shifting mechanism provides numerous and safe transition of the packer from one position to another. These packers usage is especially effective in deflected wells.
Packers are manufactured for operation in the columns 5.5-7 inches in diameter.
Basic parameters and dimensions of our packers are given in the following table.
