~Freet has manufactured six generations pre-stressed
insulated tubing(PIT) since ***9.
PIT as a high-tech product of Freet have applied two national
patents, one patent of Supercritical insulated tubing
manufacturing (***********9.9)has been awarded to
Freet(Supercritical insulated tubing is the fifth generation of
PIT).
The other patent of sulfate resistance pre-stressed insulated
tubing welding has been accepted, and product have been applied
in down-hole of PDO with great effect.
VIT (the four generation of PIT)is composed of host string,
thermo-case, coupling, seal ring and liner pipe.
The insulated tubing adopts double-walled enclosed welded
structure; the inner tube is treated with pre-stressing during
welding.
 There are multi-layer insulation structure in the annulus
space and getter in the thermo-case which can reduce heat
transfer, energy loss by convection and radiation,Â
and protect hydrogen explosion and prolong the service
life with special handicraft treatment.
VIT applies to such operating condition as the temperature of
heat carrier is not over **0℃. It mainly applies to steam
thermal recovery well with “huff and puff†and “steam
drive†as well as heavy oil well with “integration of
production and injectionâ€.
Using VIT correctly can not only reduce the heat loss of steam
injection and guarantee steam quality but also decrease casing
deformation and protect cementing casing.
The thread type of VIT is API buttress modified.
With PTFE seal ring inside coupling and insulated liner in
annulus space between inner and outer tube they can not only
assure positive confinement among pipe strings and connection
reliable but also insure the laminar flow state of steam
injection and reduce the resistance of steam transport and heat
loss in the coupling.
VIT is manufactured in accordance with the standard of
SY/T******4Â Â Pre-stressed insulated tubing .VIT with
different performance grades can meet the needs of thermal
recovery for heavy oil, super heavy oil with different depth and
horizontal wells.
The thermal conductivity(λ) of VIT is less than 0.*2w/m*℃,
which K value is less than 0.**2 BTU/(h-ft- °F)(,and equal to
grade D and E in SY/T******4), is the fourth generation PIT for
heavy oil thermal recovery leading in domestic market.
VIT both grade D and E applies to heavy oil well and super heavy
oil well, and can improve the quality of injected steam and
development effect after steaming; it also applies to production
well with high water, and protects oil string, too. At the same
time, VIT can not only save fuel and shorten steaming circle
obviously but also have distinguished economic and social
benefit.
Supercritical insulation tubes (SIT) is a new product
territory in which hasn’t been set foot in the world, and also
the fifth generation product of pre-stressed insulated tubing
.
The product can meet such well condition that temperature of
steam injection is not more than **0℃, injection pressure is
not more than *6MPa, and the well depth is less than ***0
meters.
It can meet the requirements of the steamed thermal recovery for
both heavy oil well and super heavy oil well.
