The skid-mounted drill machine described is a versatile and advanced drilling rig designed for oil and gas well drilling and exploration under 4000 meters. Here are the key features and details about this drilling machine:
**Description:**
- This drilling machine is suitable for drilling oil and gas wells with depths of up to 4000 meters, both domestically and internationally.
- It offers an optional digital-controlled auto-driller system and is powered by AC variable frequency (VF) motors, enabling drillers to optimize drilling parameters through a touchscreen interface. This enhances the quality of well holes and reduces the workload of the driller while improving efficiency.
**Structure Principles and Features:**
1. **Full DC Drive Electric Drilling:** The drawworks, rotary table, and mud pumps can independently control their speed with DC speed regulation.
2. **Complete Driller House:** The drilling rig is equipped with a full-featured driller house, where driller operations are simplified and displayed on a touchscreen, making it easy to adjust parameters.
3. **Drawworks:** The drawworks are equipped with one or several DC motors and employ a chain drive. The braking system includes hydraulic disk brakes and magnetic eddy current brakes.
4. **Independent DC Motors Driven Rotary Table:** The rotary table is driven by independent DC motors with 2 forward and 2 reverse gears.
5. **DC Electric Transmission System:** The rig's DC electric transmission system uses digital bus control, which offers strong anti-jamming capabilities, automatic troubleshooting, and mature protection functions.
6. **Drilling Parameters Instrumentation System:** The rig is equipped with a comprehensive drilling parameters instrumentation system, allowing for the indication, storage, and printing of drilling parameters.
**API Standards:** Like the previously described rig, this skid-mounted drill machine complies with national drilling rig standards and norms and holds a certificate according to the United States API 4F standards, ensuring quality and safety.
**Additional Features:**
1. **On-Wheel Rail Mounted Rig:** This rig is designed as a modular drilling rig specifically for cluster well drilling.
2. **Modular Platform:** The main rig components and auxiliary equipment, including the circulating system, genset, mud pumps, and electric control, are placed on a modular platform that can be moved quickly on rails with full setback capability.
3. **Extreme Conditions:** This rig is designed to operate in extreme conditions, such as temperatures as low as -45°C and as high as +55°C, making it suitable for various climates and environments.
4. **Single Row Cluster Wells:** The rig is capable of conducting drilling operations for single-row cluster wells, enhancing its versatility.
In summary, the skid-mounted drill machine is an advanced and adaptable piece of equipment designed for a wide range of drilling applications, offering digital control, efficient parameter adjustments, and versatility in different operating conditions and well types.
