Modular Land Drilling Rig SZJ2250M

The Modular Land Drilling Rig SZJ2250M is a heavy duty skid type modular on land drilling rig compliant with API international petroleum equipment.

Product overview

The Modular Land Drilling Rig SZJ2250M is a heavy duty skid type modular on land drilling rig compliant with API international petroleum equipment standards, specially developed for 4000 meter deep well geothermal drilling, oil gas exploration, coal bed methane exploitation and deep water well construction projects. Adopting three main module split skid mounted layout, this rig integrates high power hydraulic top drive unit, heavy load derrick substructure assembly, dual power energy saving power system and intelligent automatic control platform. It supports mud rotary drilling, air DTH percussion drilling, foam drilling and air reverse circulation drilling technologies, adapting to sand gravel strata, weathered rock, medium hard and hard rock formations. Each functional module can be disassembled independently for highway transportation, requiring only four truckloads for complete equipment shipment; low position assembling and automatic hoisting mechanism greatly reduce high altitude operation risks during rig up process. Equipped with complete mud air manifold system and real time drilling parameter monitoring module, SZJ2250M features short site commissioning cycle and low non productive time. It serves as a high efficiency modular deep well drilling solution for large scale energy engineering contractors in remote oil gas fields, geothermal bases and mountainous well site regions worldwide.

Core innovative advantages and structural features

Three Module Split Modular Skid mounted Layout

Main equipment is divided into independent transport ready skid modules. The whole set can be shipped by four standard trucks without oversized transportation permit. Low position assembling design and automatic hoisting auxiliary mechanism minimize high altitude working risk. Short distance self propelled relocation function is reserved for well site internal position adjustment, greatly shortening rig up and rig down cycle and lowering mobilization cost for scattered well site projects.

Dual Gear High power Hydraulic Top drive System

Two gear selectable torque speed output matches diversified formation requirements. Low gear mode provides high torque for hard rock penetration; high gear mode realizes fast rotary speed for high efficiency drilling. Large bore spindle allows pass through of large size drill string. Stable power output guarantees continuous heavy load operation under 4000 meter deep well working condition.

Dual source Power supply & Significant Energy saving Performance

Standard with dual 800kW generator sets, supporting both full electric drive and backup diesel power supply mode. Compared with single diesel driven scheme, electric driven mode cuts comprehensive energy consumption by more than 50%. Optimized power distribution logic reduces idle power loss under variable drilling load conditions.

Multi process Integrated Fluid Manifold Configuration

Factory integrated mud manifold, air manifold and foam pump assembly are equipped as standard. Seamless switching among mud drilling, air drilling, foam drilling and air reverse circulation drilling can be realized on site without large scale pipeline reconstruction, satisfying multi technology construction demands of geothermal, coal bed methane and deep water well projects.

Intelligent Automated Control & Multi layer Safety Interlock

Centralized integrated control cabin visualizes torque, pressure, hook load, depth and other key drilling parameters in real time. One touch operation supports collaborative control of main rig and auxiliary equipment with multi point safety interlock logic. Emergency stop linkage, derrick anti tilt monitoring and pipeline over pressure protection are embedded to enhance HSE performance for long time field operation.

High rigidity Derrick Substructure & Convenient Field Maintenance

Heavy load derrick and box type substructure adopt high strength welded structure to bear 2250kN maximum hook load. Modular layout makes core components and wearing parts accessible for inspection and replacement. Key hydraulic and electrical parts adopt internationally universal specifications, facilitating global spare parts supply for overseas projects.
