New-type Dual Sealing Multi-function Hydraulic Packer (Patent product)

After many years’ oil recovery, almost all the casing in old wells are in distortion, corrosion etc. So packer could not set and seal normally and bring operation failure. According to this problem, our engineer discussed with oilfield expert and designed this new-type dual sealing packer. There are two sets of rubber elements in packer, and all could be set reliable. One reliable setting, then whole packer could set strictly. This type of packer is mainly for resolving the problem of unset in casing which in distortion, corrosion and etc.

New-type Dual Sealing Multi-function Hydraulic Packer is composed by hydraulic anchor system, rubber element sealing system, dual slips anchor system and hydraulic setting system. Connecting structure between two series of elements are crucial for designing. Make sure two series of elements could set strictly and unset safely. One series of element seal reliable, could guarantee whole packer seal safety. When unset of packer, pull up string tool to determined shear pin cutting power to open locking system, which to release pressure on element. Two series of elements return back and packer unset.
