Experimental Research on Matrix Hardness of Impregnated Diamond Bit

Publish Date: 10 September 2015

摘要

摘要: 钻头胎体硬度是一项重要技术指标,应与所钻岩石的硬度(可钻性)和研磨性相适应。胎体硬度直接影响钻探技术经济指标的提高和钻进工艺参数的选择。试验研究表明,钻头胎体硬度分布很不均匀,差别很大。首先应从胎体烧结工艺上找原因,烧结压力偏小(5 MPa)可能是首要原因。钻头、工艺参数、操作技术等都很重要,缺一不可。钻进技术经济指标低,不一定都是钻头质量问题,要从多方面进行研究。提倡把经验打钻提高到科学打钻上来。

Abstract: Matrix hardness is an important characteristic of diamond bit.It should be suitable for hardness ( drillability) and abrasiveness of rock to be penetrated.Matrix hardness has direct influence on technical and economical indexes of drill-ing and choice of drilling parameters.Experimental research shows, that matrix hardness difference is big and not fairly well-distributed.The main reason of the big hardness difference may be low pressure (5 MPa) while sintering process of hot pressing.Diamond bit, drilling parameters and operation technology are all important.Probably low technical and eco-nomical results of diamond drilling are not connected with the bit, but with the drilling parameters and operation technolo-gy.Transition from drilling with experience to drilling with science is advocated.
