Is your drilling rig consuming too much fuel? Experienced operators share 5 fuel-saving operating techniques.

Diesel fuel is one of the main costs in drilling operations. Besides equipment factors, operator habits have a decisive impact on fuel consumption. Mastering the following 5 core techniques can significantly reduce fuel consumption while protecting the equipment.

Tip 1: Smooth Operation, Avoid Sudden Acceleration and Braking

This is the most basic and important fuel-saving habit.

Incorrect Example: During tripping in and out of the drill string, suddenly raising and lowering the drill string for speed; suddenly increasing drilling pressure during drilling.

Experienced Operator's Approach: Gentle Lifting and Lowering: When operating the handle, "gradually increase and decrease" the load, like pressing the accelerator, allowing the engine load to change smoothly.

Benefit: Prevents the diesel engine from emitting black smoke due to sudden loading (incomplete combustion). This instantaneous fuel waste is huge and severely damages the clutch and braking system.

Tip 2: Find the "Sweet Spot," Optimize Drilling Pressure and Speed (WOB & RPM)

Higher speed and greater pressure do not necessarily mean faster drilling. Finding the optimal combination is key to "high efficiency and fuel saving." Experienced operators' advice:

Soft strata (soil, sand): Use "high speed, low drilling pressure." Like cutting tofu with a sharp knife, easy and effortless.

Hard strata (rock): Use "low speed, high drilling pressure." Like hammering with a heavy hammer, breaking the rock with pressure.

Key judgment: Listen to the sound and observe the parameters. When you notice a significant drop in drilling speed and heavy engine load (pump stalling), it indicates the parameters are unreasonable and should be adjusted immediately. "Holding your breath" while drilling is the most fuel-consuming method.

Tip 3: Reduce idling and allow for timely "rest and recuperation."

Letting equipment idle for extended periods is a pure waste.

Experienced operators' practices:

Short pauses (more than 10 minutes) for connecting single sections or maintenance: Immediately reduce the diesel engine to idle speed.

Long-term waiting (e.g., waiting for instructions or materials for more than 30 minutes): Turn off the engine directly. The starting losses of modern diesel engines are far lower than the fuel consumption of prolonged idling.

Mindset shift: Treat the diesel engine like a car; turn it off when stopping to wait for someone.

Tip 4: Utilize Mud Pumps Effectively, "Prescribe the Right Medicine"

Mixed pumps are the second largest fuel consumer, and their use requires careful consideration.

Experienced Operator Tips:

* **Non-Drilling Periods:** When connecting drill pipes, measuring well depth, or when circulation is not required, promptly reduce pump flow or shut down one pump. Avoid letting the main pump run at full capacity.

* **Maintaining Mud Performance:** Maintaining good mud viscosity and shear strength is crucial for effectively carrying cuttings. Good mud performance results in high circulation efficiency, reducing the pump's load.

**Tip 5:** **Proper "Health Management," Keeping Equipment in Optimal Condition**

Equipment operating with problems is a true "fuel guzzler."

Experienced Operator Daily Checks:

* **Three Filters (Air Filter, Diesel Filter, Engine Filter):** Replace on time. Pay special attention to the air filter; if clogged, insufficient air intake will drastically reduce diesel combustion efficiency, causing black smoke and a surge in fuel consumption.

* **Tire/Track Pressure and Tension:** Insufficient tire pressure or overly tight tracks will increase rolling resistance, unnecessarily increasing fuel consumption.

Transmission System Lubrication: Regularly check the oil level and quality of the gearbox and chain box. Good lubrication reduces power transmission loss.

Summary: Experienced Operators' Fuel-Saving Techniques

"Be observant, listen attentively, move gently, and be fully aware." Fuel saving isn't about being stingy; it's about a refined "human-machine integration" approach:

Human: Cultivate smooth, predictive operating habits, adjusting flexibly according to the terrain.

Machine: Regular maintenance keeps the equipment healthy and avoids unnecessary work.

Turning these skills into muscle memory will not only make you a fuel-efficient operator but also a highly efficient and reliable equipment commander.
