摘要
钻头在钻进超研磨性地层时,胎体的磨损非常严重。文章分析测试了这类地层的可钻性,具有针对性地采用加大胎体中金刚石浓度的方法来保护胎体,极大地延长了钻头的寿命。
The wear of the matrix of a bit is severe when drilling through super abrasion strata.The drillable property of these strata was analyzed in the paper.The life time of the bit has been improved extremely by applying high diamond concentration of matrix to protect matrix properly.
