What are the precautions for well drilling equipment?

 Water well drilling rig for sale is an important equipment used for drilling. Safety is the most important when using water well drilling rigs. Let’s take a look at some safety precautions when the water well drilling machines are working.

1. The single-point inclination measurement must be carried out after the kelly is drilled and not connected to a single one. The inclinometer shall move the drilling tool once every 1-2 minutes during the trip and the drilling distance shall not be less than 2 meters.

2. Frequently observe the weight indicator and pump pressure gauge values ​​during drilling, and find that the suspended weight decreases and the pump pressure drop to find the cause immediately, first look for the ground cause, and the ground cause has been eliminated but the ground cause has not returned to normal.

3. When drilling, you should pay attention to the amount of sand in the vibrating screen. If there is more sand, you should observe whether the sand sample collapses. It is discovered whether the sand reduction is due to changes in the performance of the drilling fluid and poor rock-carrying ability. Measures should be taken in time to deal with it.

4. After drilling down, the drill bit is more than 2-3 meters away from the bottom of the well (usually a single one is mentioned above) to start the pump, and the diesel engine rotates at 800-900 pm when the pump is started. The pump pressure at the edge of the riser rises to 5MPA and the pump is removed. After it is lowered, the pump is turned on again. Open the pump several times. After observing the drilling fluid returning from the wellhead, turn on the pump, and run continuously. The rotation speed of the diesel engine is adjusted to 1150-1200 rpm when drilling. After the pump pressure is stabilized, the drill bit is lowered to the bottom of the well at a slow speed and touches the formation smoothly with light pressure and slow rotation. The roller cone bit runs for 30 minutes, and the PDC bit drills in the bottom hole shape of 0.3 meters, and then drills normally according to the designed drilling parameters.

5. Sending drills: you must concentrate your mind, you can order or slip away. It is required to send the drill evenly, see the weight gauge, and observe the lowering speed of the drum or rope, so as to keep up with the drill pressure without slipping the drill. It is strictly forbidden to pressurize the drill bit to start the drilled disc.

6. Before connecting a single root, gradually reduce the weight on the bit, so that the drill has the maximum elongation, reduce the overpressure of the bit, and extend the use of the bit.

The above is a detailed introduction to some safety precautions of well drilling equipment when working. It is still necessary when working with water well drilling equipment. It can help us reduce the occurrence of safety accidents and ensure the safety of human life and property. We YG Machinery, are a professional manufacturer of drilling rig equipment.
