6000 m on phi2.4 mm wireline
Solid wireline well-test depth reaches at least 6000 m with a 6500 m or more drum on phi2.4 mm line, deeper than the 4500 m electric-cable rating. That reach is the mechanical-intervention half of the unit.

Wireline Unit
The wireline unit is the mechanical counterpart to the logging truck: on an EQ6672CT 4x4 chassis it runs solid wireline to at least 6000 m on phi2.4 mm line (drum 6500 m or more) or electric cable to at least 4500 m on phi3.5 mm (drum 5000 m or more), with a modest 10 kN maximum pull at up to 6 m/s and a drum speed of 0 to 350 r/min. That deeper 6000 m reach on thin solid wireline is what sets it apart from a 5000 m logging cable winch, since this unit runs tools, plugs, wax cutters and downhole gauges on a line built for mechanical intervention rather than data telemetry. Because it trips no pipe, one wireline run sets or retrieves bridge plugs, cuts paraffin and takes well-test pressure in the same mobilization.
Core advantages
Designed around the operating requirement.
4500 m electric cable
For logging and gauge runs the same truck carries 5000 m or more of phi3.5 mm cable good to 4500 m or more, so well-test data acquisition and mechanical tool work share one winch package.
10 kN controlled pull
Maximum hoisting pull is 10 kN, deliberately light for wireline-scale tool delivery rather than pipe pulling. The low pull keeps tools and thin line from over-stressing, which is why depth, not force, is the spec.
6 m/s fast line speed
Hoisting speed reaches 6 m/s with the drum turning 0 to 350 r/min, fast enough to cycle tools between runs without tripping pipe. The speed range is what makes wireline intervention economical versus jointed pipe.
4x4 EQ6672CT mobility
The EQ6672CT 4x4 chassis carries the winch, hydraulic power and control cabinet into unpadded well sites; the 6700x2320x3010 footprint keeps it narrow for remote-location roads. Off-road reach is what puts the unit on scattered wireline job sites.
Tool-and-plug intervention
Without a kill job or a pipe trip, the line runs bridge plugs, wax cutters and downhole gauges in one mobilization. The 10 kN, 6000 m envelope is sized to those tools, not to heavy fishing.

Buyer questions
Frequently asked about this equipment.
Buyers comparing the wireline unit with the logging truck usually ask about winch scope and cable service.
What is the difference between Wireline Unit and Logging Truck?
The Wireline Unit focuses on mechanical downhole intervention, including tool running, fishing, plug operation and wellbore maintenance, serving well construction and troubleshooting. The Logging Truck mainly completes geological data collection and reservoir evaluation. The Wireline Unit is more functional in practical well service and on-site construction.
What main operations can the Wireline Unit complete?
It covers all conventional oilfield wireline services: downhole well testing data acquisition, bridge plug setting and retrieval, paraffin cutting, downhole tool salvaging, wellbore blockage removal and daily well condition troubleshooting, realizing multi-purpose well intervention construction.
How does the equipment ensure downhole operation safety?
The unit runs a closed-loop constant-tension control that monitors downhole line tension and depth in real time. Over-tension alarm, overload protection and emergency stop trip the winch before the line parts or the tool sticks, which is the protection that matters on wireline runs where line break means a stuck tool and a fishing job.
Can the Wireline Unit adapt to harsh climate and complex terrain?
Yes. The unit is built for field service across climates: the EQ6672CT 4×4 chassis moves it on rough access, and the drum, winch and hydraulic systems are protected for dusty and cold conditions. Its reach to 6000 m on φ2.4 mm solid wireline is the figure that matters for tool runs, plug setting and paraffin cutting, and the climate provisions are matched to the site in the quotation.
Can the Wireline Unit be configured for a specific well programme?
Yes. The configuration is settled against the well programme before the order: line type and reach (6000 m on φ2.4 mm wireline or 4500 m on φ3.5 mm cable), winch pull (10 kN class), running speed, explosion-proof grade and tension monitoring are matched to the planned tool runs, well depth and site safety rules, then written into the quotation and the factory test report.
