目前，在石油工业中提高钻井速度缩短钻井周期主要取决于钻头的工作效率和使用寿命。钻井的速度是衡量机构可靠性、合理性的最重要因素。在强化钻头的设计中比较普遍采用的方法是，在钻头表面制造一种高硬度的表层结构，这一表面是由渗碳钢、淬火钢和复合减磨材料组成。而这些 At present, increasing the drilling speed in the oil industry and shortening the drilling cycle mainly depends on the working efficiency and service life of the drill bit. Drilling speed is the most important factor to measure the reliability and rationality of the organization. The more common method used to reinforce a drill design is to create a high hardness skin structure on the drill bit surface consisting of carburized steel, hardened steel and a composite anti-wear material. And these
