CT70 CT80 CT90 CT100 CT110 Corrosion Resistance Coiled Tubing API
5ST For Oilfield Drilling
Product name: Coiled tubing
Product description: Coiled tubing products are made of special
long pipe billets that are continuously welded at the manufacturer
at one time. The finished pipe string is wound on the reel and
delivered to the user. The pipe string must be repeatedly bent and
deformed during use, and it must be rewound on the reel after use.
Continuous tubing can be used for dozens of downhole operations
such as logging, well repair, drilling, and completion; Continuous
pipeline pipe can be used in oil production, submarine pipelines,
and transportation pipes. At present, high-quality continuous pipe
products that meet user needs can be produced according to API Spec
5LCP and API Spec 5ST standards.
Performance characteristics:
Coiled tubing products have high strength, high plasticity and good
low-cycle fatigue performance, and can be used repeatedly for more
than 20 times. It is used for downhole operations in oil fields
with high efficiency, low cost, safety, environmental protection,
time saving and labor saving.
Specifications of coiled tubing:
Outer diameter of the pipe: φ25.4mm-φ88.9 mm (1inch-3.5inch)
Length of the pipe: Maximum 8000m
Implementation standard: API Spec. 5LCP, API Spec. 5ST
Product material: API Spec. 5LCP X52C ~ X90C, API Spec. 5ST
CT70-CT110
Yield strength: 483MPa-758MPa (70ksi-110ksi) for coiled tubing,

Application fields and main advantages of continuous tubing
products:
With the development of continuous tubing operation machines and
related supporting equipment, the current continuous tubing
operation technology has been applied to drilling, well repair, oil
testing, oil production, production increase, completion and other
fields. Its operation characteristics are mainly:
1. Oil wells are operated without stopping production: pressure
control equipment can make continuous tubing safe under pressure
conditions.
2. High-pressure pipeline: The continuous tubing string provides a
high-pressure channel for fluid circulation in and out of the
wellbore. In addition, hydraulic tools can be operated through the
continuous tubing string or downhole power can be provided through
the fluid pump.
3. Uninterrupted circulation: When the continuous tubing string is
lowered into the well or extracted from the well, the fluid can
still be pumped into the well uninterruptedly.
4. Rigidity and strength: The rigidity and strength of the
continuous tubing string enable tools and equipment, as well as the
continuous tubing string itself, to be pushed into and pulled out
of high-angle wells and horizontal wells.
5. Install wires and pipelines: electrical wires or hydraulic
pipelines can be installed in the continuous tubing string and
terminated at the continuous tubing reel. Operation control and
power functions can be installed between the downhole tool assembly
and the ground equipment.
