一种改进型金刚石复合片钻头
本专利技术涉及一种改进型钻头,具体是指一种改进型金刚石复合片钻头。
技术介绍
PDC钻头,就是聚晶金刚石复合片钻头。传统的金刚石钻头通常设有3-8个刀翼,这种结构的金刚石钻头为石油开采和勘探工程作出了贡献。然而,PDC钻头通常采用碳化钨或钢体为基体,以金刚石为原料加入粘结剂在高温下烧结而成。由于多种材料的存在,PDC钻头热稳定性较差,同时脆性较强,经受冲击载荷的能力较差。现有技术中的金刚复合片钻头由于钻取部数量较少,导致钻头的抗冲击能力较差,稳定性低;一种改进型金刚石复合片钻头成为整个社会亟待解决的问题。
技术实现思路
本专利技术要解决的技术问题是现有技术中的钻头钻取部数量较少,导致钻头的抗冲击能力较差,稳定性低等问题。为解决上述技术问题,本专利技术提供的技术方案为:一种改进型金刚石复合片钻头,包括钻头部和柄部,所述钻头部设置在柄部的上方,所述钻头部上设有若干钻取部,所述钻取部的前侧设有金刚石复合片,所述钻取部前后依次首尾连接,呈圆形阵列设置,所述柄部的下方设有螺纹,所述螺纹与柄部之间一体成型,所述钻头部和柄部的中心设有通孔,所述金刚石复合 ...
