油气钻井是油气开采中最重要的操作,当前最通用的钻井方法是利用钻头旋转时产生的切削或研磨作用破碎土壤或岩石,在钻头旋转过程中,钻头会受到来自土壤或岩石的巨大摩擦力,现有技术提供的耐磨金属材料,还不能满足油气钻井钻头对耐磨性能的要求,通常需要几天一换,一旦停机更换钻头,往往耗时3-5小时,严重影响钻井效率,增加钻井成本。
发明内容
本发明的目的在于:提供一种油气钻井钻头专用新型合金的制备工艺,以解决现有技术耐磨材料还不能满足油气钻井钻头对耐磨性能的要求的技术问题。
为解决上述技术问题,本发明采用的技术方案如下:
一种油气钻井钻头专用新型合金的制备工艺,包括以下步骤:

(2)淬火:混合处理完毕后,将粗加工合金放入热处理炉中加热至1000℃,升温速率大于100℃/s,保温2~3min,然后预冷到850℃,再油冷至200~250℃,保温30min,最后空冷至室温得到淬火合金;
(3)回火:淬火完成后,将淬火合金加热到210~230℃回火,保温2h,再空冷至室温得到回火合金;
(4)冷却处理和喷丸处理:将热处理完后的回火合金放入冷冻箱中深冷至-40~-60℃,冷冻4~5h,冷却处理完毕后进行喷丸处理即得到本发明油气钻井钻头专用新型合金。
作为优选地,合金混合物由如下重量百分比的组分组成:碳化钛55%、铁20%、锰15%、铬6%、镍2%、钼1.5%、石墨烯0.2%、硅0.2%、稀土0.1%。
