本文阐述了在苏联伊尔库茨克工学院金刚石钻进试验台上钻进花岗斑岩时取得的试验研究结果。本文作者根据此试验结果确定出了金刚石孕镶钻头的绝对磨损、相对磨损与钻头压力、钻头转速、冲洗液量、胎体硬度的关系式。利用这些钻头磨损的数学模型就可确定出与钻头最优绝对磨损、相对磨损相应的最优规程参数来。 This article describes the results of a pilot study of drilling granite porphyry at the Diamond Drilling Test Bench, Irkutsk Institute of Technology, the Soviet Union. Based on the results of this test, the authors determined the absolute wear and tear of diamond impregnated drill bits, the relationship between relative wear and bit pressure, bit speed, flushing fluid volume, and carcass hardness. The use of these drill wear mathematical model can be determined with the bit optimal wear and tear, the relative wear and tear of the corresponding optimal parameters to the program.
