What depth rating is this small skid rig designed for?

This 750HP class rig is rated for wells up to 2,800 meters, which makes it a cost-effective choice for shallow to medium-depth development work.

Can this rig be equipped with cold-weather features?

Yes, we can add arctic packages including heated cabins, engine block heaters, and low-temperature hydraulic fluid for operations in cold climates.

What is the footprint when rigged up?

The standard substructure layout is optimized for smaller well pads, which is useful for mature fields with limited space between wells.

Product List

ZJ40/2250LDB Rig

ZJ40/2250LDB rig adopts 3 diesel engines coupling units compounded by compounding transmission case to drive drawworks and mud pumps, with standby interfaces for auto-air compressor and energy-saving generator.
The main brake of drawworks adopts hydraulic disc brake, and the auxiliary brake is electromagnetic brake. The rotary table is independently driven: AC variable frequency speed regulating motor drives the rotary table through one two-shift transmission box and cardan shaft.

Features

1. Substructure adopts the modular mode, and blocks connect with each other by pins, which can realize quick movement.
2. Mast is front open-face "K" type mast. The five sections of mast is tower-type integral structure, which can be installed with the crown block and moved together. The supporting leg is located at base of substructure with good stability, and it is raised and laid down by drawworks as a whole.
3. The rig is equipped with frequency conversion (VFD) and MCC system. VFD is used to control AC frequency conversion motor and the automatic bit feeding motors of rotary table; MCC is used to control other devices.

Applications

ZJ40/2250LDB Rig,Land Drilling Rig,China Drilling Rig Supplier is a heavy-duty land drilling rig built for sustained drilling operations in onshore oil fields. Its skid-mounted design makes it a popular choice for operators drilling concentrated field blocks where rig moves are infrequent and ease of assembly matters more than road mobility.

- It is typically used for drilling 2,500 to 5,000 meter production wells, depending on the horsepower rating.
- Common applications include development drilling in mature onshore basins, exploration well drilling, and workover operations on deeper wells.
- Operators in the Middle East, Russia, and Central Asia often prefer skid rigs for their lower initial cost and simpler maintenance compared to complex truck-mounted rigs.

Field-Proven Design

Our skid rigs use AC variable frequency electric drive, which simplifies the power transmission system compared to older mechanical drive rigs. This design reduces moving parts, lowers maintenance requirements, and gives the driller finer control over hook load and rotary speed.

- The control system uses common industrial PLC components that are available worldwide.
- Drawworks and rotary table components are interchangeable with common API-spec drilling rig spares.
- Optional cold-weather packages are available for rigs operating in northern climates.
