Running drill pipes is a core process in water well drilling operations. A standardized operation procedure not only ensures construction safety but also improves the working efficiency of UNIQUE water well drilling rigs. This article will detail the standard steps and precautions for running drill pipes, combined with the equipment characteristics of UNIQUE water well drilling rigs.

Preliminary Preparation: UNIQUE Equipment Compatibility Check

UNIQUE water well drilling rig matching drill pipes are made of high-strength alloy materials. A targeted inspection is required before running into the well:

• Appearance inspection of drill pipes: Focus on checking whether there are cracks, dents or corrosion marks on the surface of UNIQUE drill pipes, and whether the threaded connections are intact.

• Tool calibration: Ensure that the lifting parameters of the crane match the specifications of UNIQUE drill pipes, and the models of the chuck and drill pipe holder must comply with UNIQUE equipment standards.

• Safety facilities: Place anti-skid pads and warning signs recommended by UNIQUE, and check the integrity of the wellhead protection device.

Drill Pipe Connection: UNIQUE Drilling Machine Special Process Standards

1. Model matching: Select UNIQUE corresponding models of drill pipes (diameter range 73-140mm) according to the drilling depth (such as shallow wells below 100 meters or deep wells above 500 meters) and geological conditions (loose formations/rock formations).

2. Connection operation: Use UNIQUE patented quick-connection tools to tighten the drill pipe joints clockwise, ensuring that the sealing ring is completely embedded in the groove to meet the IP68 sealing standard.

3. Precision verification: Use UNIQUE laser calibrator to detect the straightness (deviation ≤0.5mm/m) and concentricity (error ≤0.3mm) of the drill pipe. Only those that meet the standards can enter the next process.

Running-in Process: UNIQUE Water Well Drilling Rig Safe Operation Guide

Hoisting and Positioning

Through the intelligent hoisting system equipped with UNIQUE water well drilling rig, the drill pipe is accurately hoisted to the center of the wellhead. The system automatically calibrates the verticality (deviation controlled within ±1°) to ensure that the drill pipe is concentric with the wellhead.

Lowering Control

Operate the hydraulic control system of the UNIQUE water well drilling rig to lower the drill pipe slowly at a speed of 0.5-1m/min. During the lowering process, monitor the pressure parameters on the rig's instrument panel in real-time (normal range 8-12MPa) to avoid drill pipe bending due to excessive speed.

Pipe Connection Cycle

When a single drill pipe is lowered to the remaining 1.5 meters, start the quick connection device of the UNIQUE water well drilling rig to complete the connection of a new drill pipe within 30 seconds. Repeat the hoisting-lowering process until the designed drilling depth is reached.

UNIQUE Safety Operation Points

• Operators must strictly abide by safety regulations. UNIQUE water well drilling rig manufacturer provides customers with online and offline dual-track training services. Operators can communicate with UNIQUE staff at any time to apply for systematic operation training courses. In addition, ensure that each operator is familiar with the location of the emergency stop button (set on both sides of the rig) to ensure safe and controllable operation throughout the process.

• After lowering every 5 drill pipes, stop the operation to check the temperature of the threaded connection (normal ≤60℃) to prevent seal failure due to overheating.

• When encountering complex formations, activate the intelligent adaptive system of the UNIQUE water well drilling rig to automatically adjust the lowering speed and torque parameters.

By following the above standard operations, the drill pipe running efficiency of UNIQUE water well drilling rig can be increased by 20%, and the equipment failure rate can be reduced to below 0.5%. A correct drill pipe running process is the key to ensuring the quality and progress of water well drilling projects. Choose UNIQUE water well drilling rigs and supporting drill pipes to make every running operation safer and more efficient.
