Abstract

一种覆盖CVD 金刚石涂层的石油钻头用硬质合金球头齿，在硬质合金钻齿的球头表面涂覆一层化学气相沉积(CVD)金刚石膜。金刚石膜的厚度为0.01－0.2mm。涂覆采用气相沉积的办法。本实用新型的有益效果：表面涂覆了CVD金刚石膜的硬质合金球头齿，表面耐磨性提高了10倍以上，因此其使用寿命也得以大幅度提高。另外，这种钻头齿的成本要远远低于球头聚晶金刚石复合片钻齿，因此具有更大的推广价值。

Description

一种覆盖CVD金刚石涂层的石油钻头用硬质合金球头齿
技术领域
本实用新型涉及一种覆盖CVD金刚石涂层的石油钻头用硬质合金球头齿，属于钻井技术领域。
背景技术
硬质合金球头齿使用于石油钻探行业常用的一种牙轮式钻头。这种钻头常用于较复杂的地下环境，对钻齿的抗冲击性与耐磨性的要求极高。硬质合金球头齿因其价格低廉而且性能优异，是最常用的钻齿材料。
因为硬质合金的耐磨性相对于金刚石要差得多，故很多高档的牙轮钻头也要选用金刚石钻齿，目前最成功的是一种球头聚晶金刚石复合片钻齿，寿命很长。但因其价格极其昂贵，也只是少量地替代了硬质合金。
发明内容
为了克服现有技术结构的不足，本实用新型提供一种覆盖CVD金刚石涂层的石油钻头用硬质合金球头齿。
本实用新型解决其技术问题所采用的技术方案是：一种覆盖CVD金刚石涂层的石油钻头用硬质合金球头齿，在硬质合金钻齿的球头表面涂覆一层化学气相沉积(CVD)金刚石膜。金刚石膜的厚度为0.01-0.2mm。
涂覆采用气相沉积的办法。
本实用新型的有益效果：表面涂覆了CVD金刚石膜的硬质合金球头齿，表面耐磨性提高了10倍以上，因此其使用寿命也得以大幅度提高。另外，这种钻头齿的成本要远远低于球头聚晶金刚石复合片钻齿，因此具有更大的推广价值。
附图说明
下面结合附图和实施例对实用新型进一步说明。
图1为本实用新型示意图。
具体实施方式
实施例1：如图1所示，：一种覆盖CVD金刚石涂层的石油钻头用硬质合金球头齿，在硬质合金钻齿的球头表面1涂覆一层化学气相沉积(CVD)金刚石膜2。金刚石膜2的厚度为0.01-0.2mm。
