Skid Mounted Modular Drilling Rig JR SK4000

The Skid Mounted Modular Drilling Rig JR SK4000 is a standard 4000m-class medium-deep modular skid-mounted drilling rig, fully designed and manufactured in accordance with API-4F, API-7K and ISO9001 international industry standards.

Product overview

The Skid Mounted Modular Drilling Rig JR SK4000 is a standard 4000m-class medium-deep modular skid-mounted drilling rig, fully designed and manufactured in accordance with API-4F, API-7K and ISO9001 international industry standards. Developed for 3000-4000m medium-deep oil and gas well drilling, completion and overhaul operations, this rig adopts a split modular skid integrated structure with standardized segmented design. It features flexible disassembly, convenient cross-regional transportation and rapid on-site assembly, solving the problems of large volume, difficult migration and long rig-up cycle of traditional integral drilling rigs. With balanced power configuration, high structural stability and wide working condition adaptability, it is widely applied in conventional oil and gas, coalbed methane, tight gas, medium-depth geothermal and industrial water well projects, serving as a cost-effective core drilling equipment for medium-sized oilfield development and global turnkey EPC projects.

Core innovative advantages and structural features

Standard Containerized Modular Skid Design

The whole machine is divided into multiple independent standardized skid modules including derrick assembly, box substructure, main drawworks power unit and integrated control cabin. All module dimensions strictly conform to international container shipping standards, enabling segmented containerized transportation without integral heavy lifting. It greatly reduces cross-border logistics costs and shortens on-site splicing and commissioning cycle, with extremely high global deployment flexibility.

Optimized High-efficiency Power Drive System

Adopts mature and reliable mechanical drive as standard configuration, with optional SCR-DC or AC-VFD variable frequency drive upgrade. The power system achieves precise matching of lifting torque and rotary speed, realizing stable stepless speed regulation under variable load conditions. It adapts to complex medium-deep formation drilling characteristics, effectively improving drilling efficiency and reducing comprehensive energy consumption.

High-rigidity Fatigue-resistant Bearing Structure

Equipped with upgraded heavy-duty K-type open-front derrick and reinforced box-type substructure. Verified by full-working-condition finite element stress and fatigue analysis, the bearing structure maintains excellent overall rigidity, impact resistance and deformation resistance under long-term rated heavy load operation, fully meeting high-intensity continuous drilling requirements of 4000m medium-deep wells.

Integrated Intelligent Central Control System

Configured with fully sealed dust-proof driller control cabin, integrating full-process drilling parameter real-time monitoring, precise operation control, multi-level safety interlock and intelligent fault self-diagnosis functions. Centralized indoor operation avoids on-site harsh environment interference, reduces manual operation errors and significantly improves drilling safety and operational standardization.

Multi-scenario Adaptability & Low Maintenance Cost

Key structural and electrical components adopt anti-corrosion, dust-proof and weather-resistant optimization treatment, stably adapting to plains, hills, Gobi and other conventional oilfield environments. All vulnerable parts adopt universal international oilfield standard specifications, with mature and reliable system structure, low failure rate and convenient global after-sales maintenance and spare parts replacement.

How to Match the JR SK4000 to Your Project

The JR SK4000 modular drilling rig solves the classic medium-depth problem: how to move a 4000 m-class rig across a country without a month of rig-up. Rated 4000 m with a 2250 kN hook load and an 800 kW (1080 HP) drawworks, the split modular skid design breaks the rig into standard container-friendly segments that disassemble fast, ship by standard truck or container, and re-assemble on site without heavy-lift cranes. The standard mechanical drive keeps the purchase and maintenance cost low, and SCR DC or AC VFD upgrades are factory options if your well programme later demands them.

When you send a JR SK4000 inquiry for quotation, the useful numbers are the number of well pads, the distances between them, and the crane capacity available at each site — that determines how far the modular split can go in your project economics. The 12-line hoisting arrangement on 32 mm wireline and 35 MPa standpipe rating tell us the duty cycle you expect; for coal bed methane, shallow tight gas, medium geothermal or routine overhaul work, this rig is usually the most balanced capital choice in the 4000 m class.

JR SK4000 pricing is configured per module set and optional drive upgrade; a benchmark quotation is returned within two working days of receiving your pad list and well programme.
