在岩心鑽探中,粒是鑽进坚硬岩石时不可缺少的磨料,鑽粒質量的好坏,直接影响到鑽探效率的增长,而且也和鑽探成本有密切关系,因此加强对鑽粒質量問题的研究,不断提高其物理机械性能有重要的意义。本文主要是在鑄铁鑽粒、鑄鋼鑽粒及鋼絲鑽粒三个方面,对目前几个主要厂的产品加以研究討論,其中包括抗压性能、化学成份、金相組織三个問题,以求从这方面的分析比較中,找出問题的所在,並对各厂目前生产的鑽粒加以評价,在研究討論中力求找出进一步提高鑽粒質量的途徑,以期对目前的鑽粒生产有一定的指导作用。
In core drilling, pellets are an indispensable abrasive for drilling hard rock. The quality of the pellets has a direct impact on the growth of drilling efficiency, and is also closely related to the drilling cost. Therefore, research on the quality of pellets should be strengthened , Continue to improve its physical and mechanical properties of great significance. This article is mainly in the iron castings, cast steel drill bits and wire drill three aspects, the current several major plant products to study and discuss, including the compressive properties, chemical composition, microstructure three issues to Seeking from this aspect of the analysis and comparison, to find out where the problem lies, and to evaluate the current production of diamonds in the factory, in the study and discussion to find ways to further improve the quality of the diamond, with a view to the current production of diamond particles A certain guiding role.
