摘要
国产金刚石复合片的水平已有大幅度提高,但与国外复合片相比,仍有差距,主要是复合片热性能较差,为此采用有效技术措施,进行脱钴技术的研究。为充分发挥复合片的性能,研究一种复合片与牙轮的组合式钻头,已在页岩气钻进中发挥了显著的作用。
The standard of domestic diamond compact has been substantially improved.But it is still not as good as that of the other countries.The main weakness of our product is the poor thermal properties.In order to solve this problem,the research of cobalt-elimination technology has been conducted through effective technical measures.To bring the performance of the diamond compact into full play,a type of integral drill bit which combines diamond compact and roller cone has been under research and it has been playing a remarkable role in shale gas drilling.
