岩石研磨性是指岩石被钻碎时磨损钻头的能力,是岩石重要的力学性质。岩石研磨性是指岩石被钻碎时磨损钻头的能力,是岩石重要的力学性质。一般指工具的研磨性磨损,而对于工具的折断、脱落、热损坏等非正常现象,不属于研磨性磨损。研究岩石的研磨性对于正确的设计和使用钻头,提高钻头的进尺,延长其工作面的寿命(轴承的磨损及寿命问题不在此讨论之列),对于提高钻井速度乃是极为重要的问题。因此岩石研磨性的研究对钻井的技术的提高和钻井成本的的优化都有相当的价值。 Rock abrasiveness refers to the ability of a rock to wear a drill when it is crushed, and is an important mechanical property of a rock. Rock abrasiveness refers to the ability of a rock to wear a drill when it is crushed, and is an important mechanical property of a rock. Generally refers to the abrasive tool wear and tear, but for the tool off, off, thermal damage and other non-normal phenomenon, does not belong to abrasive wear. Researching the grindability of rocks is an issue of crucial importance for increasing drilling speed for the correct design and use of drill bits, increasing drill bit footage, and extending the working face life (bearing wear and longevity are not discussed here). Therefore, the research of rock abrasiveness is of great value to the improvement of drilling technology and the optimization of drilling cost.
