Design of Impregnated Diamond Bit Based on Slipping Formation
-
摘要: 为了提高金刚石钻头在坚硬致密、弱研磨性地层的钻进效率, 将弱化胎体耐磨损性能理论与切削齿非光滑设计相结合, 制作钻头进行现场试验并对胎体进行扫描电镜分析.研究结果表明：在胎体中添加适当浓度的胎体弱化颗粒, 有利于提高钻头的钻速; 经胎体耐磨性弱化处理的钻头在钻进过程中, 弱化颗粒易于从胎体表面脱落, 使其表面形成微观非光滑形态, 提高了钻头唇面与岩石的单位面积压力, 增加了孔底岩粉的研磨能力, 促进了胎体中新颗粒金刚石的出刃; 弱化颗粒浓度存在一个较优的设计范围, 过高或过低都不利于提高钻头的钻进效率和使用寿命.Abstract: Weakening matrix theory was applied on design of the drilling bit in order to improve the drilling efficiency of impregnated diamond bit in hard compact rock formation in this study. The matrix was analyzed with SEM and EDS. The results show that it can help improve drilling rate by putting matrix weakening particle into matrix. Under the process of drilling, the weakening particle can drop easily from matrix developing non-smooth surface; the pressure between surface and rock is increased and the weakening particle participates in wearing matrix, increasing abrasive power of rock powder, promoting speed of diamond metabolism. There is an optimum range for matrix weaken ratio, designing too high or too low simply can not improve drilling rate and bit life.
