Jack Up Drilling Platform

Shandong Haiding Shipbuilding Co., Ltd.  is a professional leader in China in Jack up drilling platform manufacturing with high quality and reasonable prices. Welcome to contact us. HAIDING SHIPYARD Jack up Drilling Platform is a heavy-duty oil and gas drilling equipment designed for 3-100m marine water depth, with spud leg design length of 30-150m and total platform load capacity of 3000 tons. It core-integrates a 5000m deep well drilling system, high-precision wellbore control module, and mud circulation treatment system, focusing on three tasks: deep-sea oil and gas field exploration drilling, old oilfield development well operations, and emergency rescue drilling. Aiming at the pain points of marine drilling such as "difficult deep well control, high wellbore accuracy requirements, and strong interference from complex sea conditions", it realizes stable drilling operations from shallow sea to deep sea through CCSB steel plate rigid structure (yield strength ≥235MPa), full-automatic platform leveling (±0.05°), and strong wind-wave resistance design (Grade 12 wind resistance). The drilling efficiency is 25% higher than traditional platforms, and the wellbore verticality deviation ≤0.5‰, providing a "high-reliability, high-precision, high-efficiency" drilling solution for marine oil and gas development.

Core Advantages

Strong Deep Well Drilling Capacity, Adapted to Oil & Gas Exploration Needs

5000m Deep Well System Integration: HAIDING SHIPYARD Jack up Drilling Platform equipped with a full-hydraulic rotary table drilling system (rotary table torque ≤60kN·m, maximum drill string weight 300 tons) and a 5000m deep well drilling rig (drill pipe specification 5-1/2 inches), which can penetrate complex formations such as marine sedimentary layers and basalt layers, completing oil and gas reservoir exploration wells and appraisal well operations, with a daily footage of 200-300 meters (soft formation conditions);

Mud Circulation & Purification: HAIDING SHIPYARD Jack up Drilling Platform equipped with a 120m³/h high-flow mud pump (working pressure ≥35MPa) and a four-stage purification system (shale shaker, desander, desilter, centrifuge), the mud solid content is controlled ≤5%, ensuring wellbore stability during deep well drilling and avoiding well collapse and sticking accidents.

High-Precision Wellbore Control, Reliable Drilling Quality

Full-Automatic Wellbore Positioning: Integrating GPS+Beidou dual positioning (accuracy ≤0.5m) and measurement while drilling (MWD) system (measurement accuracy ±0.1°), real-time monitoring the well deviation angle and azimuth angle, adjusting the weight on bit (control accuracy ±0.5kN) through the automatic bit feeding system, ensuring the wellbore verticality deviation ≤0.5‰, meeting the trajectory control needs of directional wells and horizontal wells;

Platform Stability Compensation: HAIDING SHIPYARD Jack up Drilling Platform adopts a three-axis inclination sensor (accuracy ±0.02°), when the platform tilts due to wind and waves, the full-automatic leveling system adjusts the spud leg lifting in real time (adjustment accuracy ±0.05m), ensuring the platform level error ≤0.05° during drilling operations, avoiding wellbore trajectory deviation caused by platform shaking.

Full Water Depth Adaptation, High Tolerance to Harsh Environments

Spud Leg & Structure Adaptation: HAIDING SHIPYARD Jack up Drilling Platform adopts 4 sectional truss spud legs (diameter 2.0-2.5m, material: CCSB marine steel plate) with customizable length of 30-150m, adapting to 3-100m water depth: 30-50m short legs for shallow sea (3-20m), 50-80m medium legs for medium sea (20-50m), 80-150m long legs for deep sea (50-100m); spud cans adopt expandable design (contact area ≥80㎡, welded with CCSB steel plate) to prevent sinking into seabed soft soil;

Harsh Environment Resistant Design: The HAIDING SHIPYARD Jack up Drilling Platform has Grade 12 wind resistance, wave resistance height ≤6m, current resistance speed ≤2.5 knots. The drilling module is equipped with IP67 dustproof and waterproof sealing, and the mud system is equipped with a low-temperature heating device (normal start at -20℃), which can operate during the South China Sea monsoon period and Bohai Bay winter ice period, ensuring uninterrupted drilling tasks (CCSB steel plate impact energy ≥27J at -20℃, meeting low-temperature toughness requirements).

Modular Deployment, Convenient Operation & Maintenance

Sectional Transportation & Assembly: The HAIDING SHIPYARD Jack up Drilling Platform is split into 6-8 sections (main platform section, spud leg section, drilling module section, all welded with CCSB steel plate) with maximum single-section weight ≤120 tons, which can be transported globally by semi-submersible ships and ocean-going barges; on-site assembly is completed with flanges + prestressed bolts, and takes 10-15 days with marine floating cranes, 30% shorter than the deployment cycle of traditional drilling platforms;

Modular Maintenance of Drilling Equipment: Core equipment such as rotary tables and mud pumps adopt modular design, which can be disassembled and replaced as a whole in case of failure, reducing maintenance time to 12 hours/time; the spud leg rack is quenched and tempered with CCSB steel plate (hardness ≥200HB), with service life ≥25 years in deep-sea environment, and annual maintenance cost 25% lower than traditional platforms.

Detailed Technical Parameters

Core Application Scenarios

Deep-Sea Oil & Gas Field Exploration Drilling

Exploration Well Operation: In deep-sea oil and gas exploration areas (water depth 50-100m) of the South China Sea and East China Sea, drill 5000m deep exploration wells, analyze formation lithology and oil and gas shows through MWD system, and obtain oil and gas reservoir parameters; the CCSB steel plate platform structure resists wind and wave impact, ensuring wellbore stability during drilling, with exploration well success rate ≥90%;

Appraisal Well Operation: For discovered oil and gas structures, drill 3000-4000m appraisal wells to test oil and gas productivity and reserves; the mud system accurately controls solid content to avoid polluting oil and gas layers, providing a basis for subsequent development well design.

Old Oilfield Development Well Operation

Production Well Drilling: In old oilfields (water depth 10-50m) of the Bohai Bay and Beibu Gulf, drill 2000-3000m production wells, and use directional well technology to realize multi-layer mining; the platform's modular design can quickly switch drilling modules, completing surface casing operation of 1 production well per day, with efficiency 25% higher than traditional platforms;

Workover Operation: For problems such as casing damage and wellbore blockage in old oilfields, conduct workover operations to replace damaged casings and clean wellbores through the drilling system; the CCSB deck steel plate has stable load-bearing capacity, capable of carrying 100-ton workover equipment for long-term operations.
