Abstract

Abstract. The cutting mechanical properties of impregnated diamond bit depend on the performance of its cutting elements. Aiming at the factors affecting the cutting element performance of impregnated diamond bit, the laboratory rock breaking experiment of impregnated micro bit is carried out. The results show that the breaking work ratio and unit wear first decrease and then increase with the increase of diamond particle size and concentration when drilling sandstone; the rock breaking efficiency and wear resistance are the highest when the concentration is 125 %. The breaking work ratio first decreases and then increases with the increase of diamond particle size when drilling limestone; the rock cutting efficiency is the highest when the concentration is 100 %. With the increase of diamond particle size, the breaking work ratio increases and the unit wear decreases when drilling granite; the rock cutting efficiency and wear resistance are the highest when the concentration is 150 %.

浸渍微钻头钻井性能分析

摘要浸渍金刚石钻头的切削力学性能取决于其切削元件的性能。针对影响浸渍金刚石钻头切削元件性能的因素，进行了浸渍微钻头的室内破岩试验。结果表明:钻取砂岩时，随着金刚石粒度和浓度的增加，破碎功比和单位磨损量先减小后增大;当浓度为125%时，破岩效率和耐磨性最高。钻取石灰岩时，随着金刚石粒度的增大，破碎功比先减小后增大;当浓度为100%时，岩石切割效率最高。钻取花岗岩时，随着金刚石粒度的增大，破碎功比增大，单位磨损量减小;当浓度为150%时，岩石切削效率和耐磨性最高。

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
