Produced by Shandong Yiguang Drilling and Mining Technology Co., Ltd.diamond compact drill bitKnown as one of the three major drilling technologies in the world in the 1980 s, it is one of the commonly used accessories in mining engineering.It belongs to an integrated drill bit with simple structure, high strength, high wear resistance and impact resistance.
Diamond composite piece drill bit is a drill bit for cutting heads. It is suitable for drilling in soft-medium-hard formations when used in the field. It has fast speed, long footage, long service life and small downhole accidents.and other characteristics. When damage occurs, it can be repaired. The repaired diamond drill bit is almost the same as the one in front of the factory, which can save costs. So how can the diamond drill bit play its best role?Big advantage?
1. Preparation before drilling: check whether there is damage to the drill body, tooth loss, etc. on the previous drill bit, make sure that the bottom of the well is clean and free of falling objects, carefully handle the drill bit, and place the drill bit on the rubber pad or wood board.. It is forbidden to place the drill directly on the iron plate.
2. Buckle-up: clean the male or female buckle of the drill bit and apply thread oil, clip the buckle shackle on the drill bit, and lower the drill string to make it contact with the male or female buckle.
3. Drill-in: lower the drill bit slowly, especially slowly through the rotary table, blowout preventer and casing hanger to protect the cutting teeth. Pay attention to the blocked interval during the last trip.Make the drill bit pass slowly when encountering diameter reduction and dog leg.
4. Rinsing: it is not recommend to use diamond bit for interval remarking. If it is necessary to ream, the rated displacement shall be adopted.
5. Modeling. Keep the rated displacement and lower the bit to the bottom of the well. Keep the weight on bit constant and adjust the drilling rate to obtain the best combination of drilling parameters.
6. Normal drilling: When encountering strong abrasive or hard sand and mudstone, reduce the drilling speed to extend the life of the drill bit, and adjust the drilling speed and drilling pressure to maintain the best drilling efficiency when encountering formation changes or interlayers..
