ZJ50 1500HP Skid-Mounted Land Drilling Rig（Drilling depth: 5,000 meters）

The ZJ50 1500HP skid-mounted land drilling rig is designed for medium-deep onshore drilling projects with nominal drilling depths of up to 5,000 meters, depending on drill pipe size, well program and actual operating conditions.

This rig is suitable for oil, gas, geothermal and other land drilling projects requiring reliable hoisting capacity, stable mud circulation, practical field operation and configurable supporting systems.

The ZJ50 rig can be supplied as a main rig system or as a complete drilling rig package according to the customer's project requirements. The final configuration may include the mast, substructure, drawworks, rotary system, traveling system, mud pumps, solids control system, well control equipment, power and control system, auxiliary equipment and recommended spare parts.

The ZJ50 skid-mounted drilling rig is a widely used 1,500HP land drilling rig platform for medium-deep drilling operations. Compared with smaller rigs such as ZJ30 and ZJ40, the ZJ50 rig provides higher hook load, stronger drawworks capacity and larger mud circulation capability. Compared with ZJ70 rigs, it can offer a more economical solution for projects that do not require 7,000-meter deep-well capacity.

A complete ZJ50 drilling rig package may include:

• Mast and substructure
• Drawworks
• Crown block
• Traveling block and hook
• Rotary table
• Swivel
• Power and transmission system
• Mud pumps
• Solids control system
• High-pressure mud manifold
• Well control equipment
• Driller cabin
• Electrical control system
• Power generation system
• Air supply system
• Auxiliary tools
• Recommended spare parts
• Technical documentation

The final equipment scope shall be confirmed according to the customer's drilling program, technical specification and contract.

The ZJ50 1500HP land drilling rig is suitable for:

• Medium-deep onshore oil wells
• Natural gas wells
• Geothermal drilling projects
• Development drilling projects
• Exploration drilling projects
• Desert land drilling projects
• Cold-area land drilling projects, subject to adaptation requirements
• Coastal land or beach drilling projects, subject to site conditions
• International drilling projects requiring modular transportation and export support

Before quotation, the rig configuration should be reviewed according to the required drilling depth, drill pipe size, casing program, mud pump capacity, BOP pressure rating, site conditions and destination logistics.

The following specifications are for general reference. Final parameters shall be confirmed according to the selected configuration and contract.

Mast and Substructure
The mast and substructure are designed to support the drilling operation, rig-floor equipment and wellhead clearance requirements. The rig-floor height and clearance under the rotary table beam should be selected according to the BOP stack, wellhead arrangement and operating requirements.
 

Drawworks
The drawworks is the main hoisting system of the ZJ50 rig. Depending on the selected drive type, the drawworks can be configured with suitable braking, speed regulation, automatic feeding and control functions.

Typical considerations include:

• Rated power
• Main brake system
• Auxiliary brake system
• Speed regulation method
• Automatic bit feeding function, where required
• Control and monitoring system
• Maintenance accessibility

Rotary System

The rotary system is selected according to rotary table opening, torque requirement, speed range and drilling operation habits. Electric or VFD-controlled rotary drive options can be evaluated when independent speed regulation is required.

Traveling System
The traveling system normally includes:

• Crown block
• Traveling block
• Hook
• Drilling line
• Associated accessories

The rated capacity and reeving arrangement should match the required hook load and drilling depth.

Mud Circulation System

Mud circulation capacity is one of the most important parts of a ZJ50 rig package. The mud pump model, quantity and power should be selected according to hole size, drilling depth, pressure requirement and required flow rate.

Typical mud circulation equipment may include:

• F-series triplex mud pumps
• Mud tanks
• Shale shakers
• Vacuum degasser
• Desander
• Desilter
• Centrifuge
• Mud agitators
• Mud guns
• Mixing hopper
• Mud manifold and pipelines

Well Control System

The well control package can be configured according to the required pressure rating and well program.

Optional well control equipment may include:

• BOP stack
• BOP control unit
• Choke manifold
• Kill manifold
• High-pressure valves
• Drilling spool
• Spacer spool
• Well control pipelines and accessories

Power and Control System
The ZJ50 rig can be configured with different drive and control solutions according to the customer's project requirements. Mechanical, LDB, DB and AC VFD options can be evaluated based on the customer's operating habits, automation requirements, local maintenance capability, power availability and budget.

Before purchasing a ZJ50 1500HP drilling rig, most international buyers carefully review the following points:

• Whether the rig capacity matches the required drilling depth and drill pipe size
• Whether the maximum hook load is suitable for the expected well program
• Whether the drive system is suitable for local operation and maintenance conditions
• Whether mud pumps, solids control equipment and well control equipment are included
• Whether the BOP pressure rating meets the project requirements
• Whether the rig-floor height can match the required BOP stack
• Whether the rig can be customized according to local site conditions
• Whether the equipment can be inspected before shipment
• Whether spare parts, manuals and technical documents are available
• Whether warranty terms are clearly defined before contract signing
• Whether shipping dimensions, weight and packing details can be provided
• Whether real equipment photos, videos and inspection records are available for review

Rongli supports customers during the selection stage by reviewing the drilling program and preparing a suitable technical proposal according to the actual project requirements.

For drilling rig projects, real photos and videos are important for customer evaluation. They help buyers understand the actual equipment condition, structure, manufacturing quality and preparation progress before making a purchasing decision.
According to project availability, we can provide:

• Real equipment photos
• Factory inspection photos
• Equipment testing videos
• Mud pump test videos
• Drawworks and rotary system inspection videos
• Refurbishment process photos, if applicable
• Loading and packing videos
• Container loading or breakbulk loading photos
• Field installation or operation records, where available
