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

ZJ40/2250D Rig

ZJ40/2250D drilling rig is DC drive module with full digital DC control system. Drawworks, rotary table and mud pump are driven separately: drawworks and mud pump adopt one-to-two control, rotary table adopts one-to-one control.
The three generator sets interconnect through three SCR control cabinets to control 7 sets of DC motors: 2 sets of motors are compounded to drive drawworks, 1 set drives rotary table individually, and the other 4 sets of motors (each two compounded) drive 2 sets of 1300HP mud pumps.

Features

1. The substructure adopts modular structure with pin connection between blocks, realizing quick movement.
2. Mast is front open-face K type, five sections of mast is whole tower structure which can be installed with crown and moved as a whole. Supporting leg is base seat under substructure with good stability, using drawworks power to raise or lower as a whole.
3. Drawworks is driven by DC motor with high power utilization rate. The total number of drawworks shifts can be up to 4+4R, realizing stepless speed regulation.

Applications

ZJ40/2250D 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.
