Our AdvantagesThis large channel allows fluid to flow freely
as the packer is run, recovered, and circulated, greatly reducing
cartridge friction and avoiding ball-tooth collisions. The packer
can be used in high pressure Wells where a hydraulic anchor can
effectively prevent the packer from going up. At the same time, the
pressure also acts on the balance piston, which moves down against
the center pipe and the seal sleeve. This principle eliminates
excess set load and keeps the packer's bypass balance channel
closed. Characteristics 1, can be safely set in all levels of
casing; 2, reliable sealing system, in the operation can withstand
the pressure difference up and down; 3, ground control bypass
channel and pressure balance valve; 4, balance piston structure to
strengthen the stability of the tool under pressure; 5. Automatic
J-type device can easily achieve setting and unsealing, and can be
set several times after entering the well; 6. Lifting the tubing
will first open the bypass valve to balance the pressure, to ensure
the safety of unsealing operation; 7, can withstand high pressure,
7 "and below specifications can withstand up to 70MPa (10000psi)
pressure difference. Iv. Specifications and models Product
DescriptionIn oilfield drilling engineering, oil drill pipe is the
main component connecting ground rotation system, lifting system
and circulation system with drill collar and drill bit. Through
these components, the rotary wheel drives the drill bit to rotate,
the big hook drives the drill bit to lift, and the mud is sent to
the bottom of the hole to form circulation, so as to realize the
drill bit breaking rock layer and continuous drilling.Great Petro
anti-sulfur drill pipe is a special drill pipe independently
developed by Great Petro to meet the needs of oil and gas
exploration and drilling in areas with sulfur and high sulfur
content, which has the stress corrosion resistance of hydrogen
sulfide.Product advantageOn the basis of the first generation of
DT-S 95 and DT-S 105 antisulfur drill pipe suitable for use in
moderate H2S corrosion environment, by optimizing the chemical
composition of materials and heat treatment process, The second
generation of DT-SS 75, DT-SS 95 and DT-SS 105 anti-sulfur drill
pipe suitable for use in severe H2S corrosion environment has been
developed. The performance indexes of the SS series of anti-sulfur
drill pipe meet the requirements of IRP1.8, NACE MR0175 and
ISO15156 standards.Product specificationProduct size: Covers all
API standards from 2-3/8 "to 6-5/8"Steel grade: DT-S 75, DT-S 95,
