Chengdu Rongwanda Drilling Equipment Co., LTD is one of the domestic largest Company which engaged in diamond bit professional manufacture and sale. Company adopts world’s advanced design concept and manufacturing process to design and manufacture diamond bit for oil & gas field drilling and coring, and other special-purpose drilling bits.
1. To keep the mud clean, prevent the impurities from blocking the drill bit port., and affect the use of the drill bit.
2. Drill down to control the speed and prevent the sudden stop, and make the roller bit better.
3. Keep the two pumps in good condition.
4. Pay attention to the drill bit and prevent the drill bit slipped.
5. Adjust the drilling parameters in time when encountering a bad drill or bouncing drill.
6. Before drilling the cone bit, circulate for about 10 minutes, with 1-2 tons of drilling for about 0.5 meters, and gradually pressurize to 6-8 tons of drilling. The drilling is uniform speed to prevent the sudden damage of the teeth.The drill pressure generally is not more than 10 tons. When you are slow to drill, we should see clearly, if it is because of the reason for the interlayer to be patient, do not blindly add pressure.
