1. Reasonable engine power configuration, high lifting speed and high working efficiency.
2. In the transmission system, the hydraulic torque converter of oilfield service machine makes the transmission stable and flexible. It can be adjusted steplessly and the using rate of engine power is high.
3. The drum of 150HP workover well-servicing rigs adopts double-end input clutch. It can realize the reverse rotation, and benefit for the falling of the hook.
4. The mast of oilfield service machine is pneumatic load-bearing type with steady structure.
Applications
150HP Workover Rig,Workover Well-Servicing Rigs,China Oilfield Service Machine Manufacturer is engineered for up to 1,500 meter shallow producing wells. It is built for reliable daily operation in demanding onshore oil and gas environments, with design choices that match the real-world needs of local well servicing companies in mature shallow oil fields.
- Primary use: routine pump changes, light well servicing on shallow stripper wells.
- The rig/unit is a common sight in mature onshore basins across the Middle East, Central Asia, Africa, and Southeast Asia.
- It is selected by operators who value straightforward maintenance and locally available spare parts over overly complex control systems.

Reliability for Daily Well Service Work
A hp workover rig is built for daily well service operations, with a maximum pulling force of kN matched to . Unlike exploration rigs that stay on one well for weeks, workover crews move between wells every 1-2 days, so reliability during routine pulls and pipe trips directly impacts job profitability.
The rig's hydraulic system and hoist are designed for regular maintenance intervals of about , covering oil changes, filter replacement, and brake pad inspection. Standard wear parts (brake bands, wire line slips, swivel seals) are stocked as common spare parts that most oilfield service shops carry, so crews don't have to wait days for specialized parts when a component fails on location.
We size the winch and hydraulic system to run continuously for 8-12 hour shifts, which is the typical length of a workover job on a producing well. This avoids over-stressing components during long fishing or stuck pipe recovery operations, which are common on older producing wells.
Choosing the Right Workover Rig Size
For shallow wells under 800 meters, a 150hp unit provides enough pulling force to handle routine tubing changes, pump replacements, and routine well cleanout without the extra cost of a larger rig. If your wells regularly have stuck pipe or deep scale issues, stepping up to the next horsepower class will reduce time spent on fishing operations.
FAQs
Q: What size tubing can this rig pull?
A: Smaller workover rigs in this range are designed for 2-3/8 inch to 3-1/2 inch tubing, which is standard for shallow producing wells.
Q: Can this rig be set up on well pads without a crane?
A: Yes, most small workover rigs can self-mobilize and rig up without a separate crane, saving on mobilization costs for remote wells.
Q: What BOP height can the mast accommodate?
A: The mast is designed to accommodate standard annular and ram BOP stacks for well control during routine servicing operations.
