The swabbing unit is rated by a drum-dependent lifting envelope: up to 120 kN at minimum drum diameter, down to 80 kN as the drum fills, with a maximum working depth of 3350 m. Within that window it runs a wireline swab cup that seals against the tubing wall and lifts the liquid column to surface, which is the standard kickoff for low-pressure, liquid-loaded and newly completed wells that will not flow on their own. Because it lifts fluid rather than tripping pipe, the truck is the light, low-cost way to unload kill fluid, accumulated water and edge-well loading and restore natural production without mobilizing a full workover rig.
Lifting capacity is stated at drum diameter: 120 kN at minimum drum diameter and 80 kN at full drum, which is why the 3350 m depth limit is matched to rope count rather than engine power. Operators plan runs against that pull curve, not against a nominal peak.
Maximum working depth of 3350 m covers the shallow-to-mid wells where liquid loading kills flow: new completions, edge wells and old low-pressure producers. Beyond that window a larger unit is specified, which keeps this truck sized to its cheapest viable job.
The swab cup forms a traveling seal inside the tubing and lifts the liquid column rather than circulating it. That piston action is what removes kill fluid and accumulated water fast, turning a loaded well back to natural flow.
Because the package is a drawworks and mast on a service chassis rather than a rig floor, it reaches scattered edge-well locations a full workover unit cannot cost-justify. The 80-120 kN class is the whole point: enough pull to unload, small enough to drive between wells.
A depth counter and constant-tension line control read off the drum as it winds, so each run's fill height and pull are recorded against the 3350 m limit. The operator sees when the liquid level is reached instead of guessing by sound.
The swab cup is the scheduled consumable, sized to the tubing it seals, while the drawworks and wireline are rated to the 80-120 kN envelope. Routine cup replacement rather than major overhaul is what keeps a marginal-well program economical.

The Swabbing Unit is dedicated to oil well downhole fluid recovery and production activation. It lifts accumulated liquid, kill fluid and residual fluid out of the wellbore by swabbing operation, eliminates liquid suppression on oil layers, restores natural production capacity of low-pressure oil wells, and is widely used for new well startup, old well restoration and daily maintenance of marginal wells.
Compared with a full workover rig, the swabbing unit mounts on a smaller service chassis, rigs up fast and costs far less per job. It needs no complex auxiliary procedures, disturbs the formation minimally, and restores flow in water-logged low-rate wells at a fraction of a workover spread.
Yes. The standard model is rated to 3350 m working depth; deeper swabbing programmes are discussed against the wireline and drum combination. Equipped with high-tensile steel wireline and a drawworks rated to the 80–120 kN lifting envelope, it holds stable pull and a reliable cup seal on long runs.
Yes. The unit is specified for continuous swabbing service across climates, with the winch and drum rated for the 80–120 kN lifting envelope at up to 3350 m working depth; climate provisions are configured to the site. Confirm the expected well count and service window in the inquiry so the drum configuration and support scope are matched to the workload.
Yes. The configuration is settled against the well programme before the order: swabbing depth within the 3350 m rating, lifting speed, explosion-proof grade, line-tension monitoring and wear-resistant drum lining are matched to the well depth, liquid load and site safety rules, then written into the quotation and the factory test report.
Commercial terms are confirmed in the quotation for the exact configuration, quantity and destination.

A boiler truck earns its keep by heat, not by pressure: this unit delivers working water at up to 280 through a fired tube package rated at 6 or 9.8 MPa, at a hot-water or steam output of 1.26, 1.8 or 3.0 t/h.
Three pulling ratings define this coiled tubing line: ZLG155/38 holds 155 kN continuous tension, ZLG225/45 holds 225 kN and ZLG290/50 holds 290 kN, with laying depths of 3600, 4200 and 5900 m on 1.5-inch tubing.
This unit combines two duties in one truck: a triplex plunger pump rated up to 35, 40 or 70 MPa at 50, 60, 80 or 100 m3/h for cold high-pressure flushing, and a fired heater that delivers hot wash at 20 MPa and 160, at…
The YCZ swabbing tool series covers integral and semi-sectional builds at 5 1/2 in and 2 1/2 in sizes, with a maximum load-bearing capacity of 80 kN on the YCZ01 and YCZ02 and 50 kN on the smaller YCZ03.
