Description：
|
The tractor is a kind of tool to convey the downhole tools in the horizontal well and highly deviated well. When logging in the horizontal well and highly deviated well, if the downhole tools couldn’t down to the destination well section by its gravity, the tractor can convey the downhole tools to the right position by its power unit. Compare with the drill pipes transportation, it can save logging time, lighten the working strength of homework and reduce the risk of construction. And no need well derrick, can convey greater distance compare with the continuous pipeline transportation and with no influence by the well depth.

INTRODUCTIONCOMPOSITIONTECHNICAL SPECIFICATIONSADVANTAGES
The tractor is a kind of tool to convey the downhole tools in the horizontal well or highly deviated well. When logging in the horizontal well or highly deviated well, if the downhole tools couldn’t down to the logging interval by its gravity, the tractor can convey the downhole tools to the right position by its power unit. Compare with the drill pipes transportation, it can save logging time, lighten the working strength of working and reduce the risk of construction. And no need well rig, can convey more loggerr distance compare with the continuous flexible pipe transportation and with no limit by the well depth.
The tractor has its own independent system, includs downhole tools and surface controller. It should be work together with the logging winch.
The logging tools can be connected at the top or the bottom of the tractor.
Max. logging temperature: 175℃
Max. logging pressure: 140MPa
O.D.:ф80mm
Length: 7.1m（4-drive）
Weight: 160Kg（4-drive）
Power voltage: 0~600VDC
Max. traction speed: 9m/min
Max. load: 810Kgf（6-drive）
Casing size: 4.5″~9.625″
Traction direction:
two-way(push-pull)
Applicable cable: monopole cable
or 7-conductor cable
-
Applicable for all kinds
-
Monopole cable can be used since the strong traction ability
for load.
-
7-conductor cable for the large traction requirement
-
Using 7-conductor cable for the logging tool, 4-conductor for
the power supply, max. current is 6A.
-
The 7-conductor cable logging tool only should be
connected at the bottom of the tool string.
-
The tool has simple appearance and high safety.
Easy maintenance since the simple
appearance. Less parts bare in the drilling liquid, It can be take back
automatically by the spring force in case of the driver power failure. Reduce
the risk of getting stuck in the well.
-
Has a logger time continuous working ability
-
Strong tool driving wheel has the big friction with the casing.
It still can work even if the driving wheel has some abrasion,
guarantee the long distance driving, reduce the use-cost.
It can be work for the large traction
requirement since the maximum traction could be reach at 810kg. It has high
efficiency and small hot, can be used in empty hole with no well liquid, wide
range application.
-
Can be used for perforating
It has strong load ability, better
stiffness, can shock resisting impact perforation, can be used for
perforation for the horizontal well with additional auxiliary perforation tool.
The tool adopt the idea of modular design,
the driver can be exchanged each other, many ways combination, select the
combining mode basis the application, and different load ability for the
different combining form.
-
Unique ability for through the steps and walking along the wall
It has the ability for through the steps
and walking along the wall when equip with 4-driver section or 6-driver
section.
The load
ability for different combining form
