API Swellable Hydraulic External Casing Packer For Oil Well Drilling Tools
1. Description of packer
Casing Packer (casing external packer) uses hydraulic expansion type structure, mainly be used in the complex wells'(oil,gas,water) completion project, to achieve downhole packer and bridging and in favor of improvement of the quality of completion. The practice proved that this tool have characters of easy operation,wide adaptability, it has a very important position in the completion project.
Hydraulic expansion packer mainly consists f of e valve m system t joint assembly, rubber barrel, central tube ,casing sub. The valve systems is divided into axial valve system and radial valve system. Radial valve system is composed of a a set of three valve.
2. Working Principle
In the construction process, the replace plug will touch off the
breaking stick which is sealed in the intake hole when the replace
pluge through the valve joint of the packer. The replace pluge will
make the casing form seal when it move to the spoiler(we also can
use the pitch or blind plate and pipe string process structures
make casing form seal, for these process pipe string structure
without plug through so we should take off the breaking stick in
advance), Bie pressre liquid through the valve system fo intake
hole into the open valve system of intake hole into the open valve.
when the pressure to achieve set valve, the pin on the ope valve is
snapped. open valve open, and at the same time, single valve is
opened, the fluid through limiting valve into the expansion cavity
between center pipe and rubber cylinder, make packer inflation and
wall close contact form seal.
When the pressure of the expansion cavity reach the value of
limiting valve's pin pressure, pin shear, liemeitng valve closed
and will make intake hole sealing, the caing pressure valve have no
influence on the pressure is zero, open valve automatic locking,
realize premanent closed,(see chart 3)after the downhole pressure
operation dose noe affect the packer fate.
In some specaail pipe string process well, also can use the inner
pipe tools to a packer, achieve completion purpose(Such as packer
direct completion and packer in the screen between the packer and
completion method).
