Product Description
RTTS Packer
Usage: RTTS Packer is extensively used in well
testing, HP acidification, cementing, other oil formation
improvement and so on.
Structure features: RTTS Packer has advantages of
HT/HP resistance, sealing well, compacted in design, reliable
setting, small unset power and etc. It can accomplish many function
operations in one single trip, and high success rate of
performance in oil sites.
PT Packer
Usage: PT Packer could be used in well
testing, acidification, fracture, perforation, cementing and many
other down-hole operations.
Structure theory: PT Packer is one kind of packers
which has slip structure, high load and compressible setting
method. It could keep the high differential pressure from one side
of casing. PT Packer has larger by pass area below elements, which
could reduce suction in running tools and balance two sides of
pressure before setting. The by pass is closed by seal valve. Well
testing apply large by pass structure firstly, then apply hydraulic
hold-down slip top coupling structure.
Y******5/**8 Packer
Usage: Y******5/**8 Packer could be used in
stratified well testing, oil recovery, water plugging and
acidification. This kind of packer could work with slip type packer
or backup slip together.
Structure theory: Running string tools according
to setting height and space between tubing and top flange. Below
packer, there is tailpipe, slip type packer or backup slip as
support. String weight compresses rubber element to increase the
ID, which could block and seal oil or casing annular. Pull string
upside, rubber element reinstate again.
Features: Increase shear pin structure to avoid
wrong setting. When running string tools, wrong setting would
happen if Packer stopped to move down and under string weight.
Shear pin structure could prevent from wrong setting if running
string tools and cut shear pins to down into well.
Y******5/**8 Packer
Usage: Y******5/**8 Packer could be used in
stratified well testing, oil recovery, water plugging and
acidification. This kind of packer could work with slip type packer
together.
Structure features: Increase pressure by tubing to
setting piston. Cut setting shear pin when tubing pressure is high
enough, setting piston push spring sleeve up and compress rubber
element to get annulus. Spring connect with spring seat, which
could prevent rubber element return back as releasing tubing
pressure.
Pull up string tools, cut shear pins as soon as the friction
between rubber element and casing internal surface is higher than
cutting power of unsetting shear pins. Spring and spring sleeve
move down together, to unset Packer.
Y******5/**8 Rail Type Packer
Usage: This type of packer could set by pulling up
& pushing down middle tubing operation conveniently. It is
mainly used in stratified well testing, oil recovery,
hydraulic pump, fluid pump and etc.
Structure features: When running string tools as
required height, steel ball moves from end side of short slot to
end side of long slot. Slip open to touch casing surface. String
weight compresses rubber element to enlarge diameter, which could
seal and block oil and get annulus. Pull up string tools, steel
ball moves to end side, cone-shaped seat leaves slip and slip
returns back, rubber element returns back and unset packer
meanwhile.
