• Combining with domestic process characteristics of coiled tubing
units, Petrokh develops double truck mounted coiled tubing unit which
meets domestic vehicle dimension requirements.
• With the design idea
of humanization, safety and stable performance, this unit is designed
to have reasonable layout, safe transportation and good off-road
performance, which is ideal for mountainous areas such as Northern
Shaanxi, Sichuan and Chongqing areas. This unit adopts humanized designs
such as integrated quick connection panel, hydraulic integrated quick
connection, rear protection with adjustable pedal and one-key control
cabin limit to ensure convenient operation and maintenance. Some key
components such as injector and coiled tubing reel have been proved to
have good performance after long time of use in oilfields.
Competitiveness
• Compared with the products of both domestic and foreign competitors,
our products has optimized the following aspects to improve overall
performance:
• Optimize the layout of the whole unit to ensure
reasonable load distribution. Move the power pack forward to reduce the
load of front axle and enlarge the maintenance space for the pump drive,
drive shaft and hydraulic pumps.
• Moving the power pack forward can
release more space under the control console, which make it more
convenient to maintain the hydraulic and electric components inside the
control console on one hand. On the other hand, it is more convenient to
observe the tubing reel condition from the control cabin.
• The
control cabin is optimized to be integral lifting, which improves seal
and heat prevention performance, convenience in maintaining control
console and the user experience.
• The tubing reel adopts quick-change sprocket set structure which makes the chains can be changed in 10 seconds.
•
Optimize the upper and lower ladders of the control cabin to ensure
convenience and safety (reversing platform and ladder with hook).
•
Rear protection integrates reversing pedal structure. Thus, the hose
reel can release and retract hose conveniently and operators can climb
to the subframe for operations easily here.
• The drive shaft is protected with guard which has openings for convenient maintenance.
