SY系列深孔硬岩孕镶金刚石钻头的研究与应用

Study and Application of SY Series Impregnated Diamond Bits for Deep Hole Drilling in Hard Rocks

针对山东莱州纱岭、前陈,招远水旺庄等典型的深孔硬岩强研磨性地层情况,对孕镶金刚石钻头在原料、配方、模具以及各项生产工艺等方面做出设计、研发和改进,并对钻头进行长时间、多层次的试验,根据各项理论指标结合试验数据,确定钻头的设计参数,研发出了适合深孔硬岩强研磨性地层使用的孕镶金刚石钻头。

According to the typical situation of deep hole in hard rocks and strong abrasive formations in some areas of Shandong, the design, development and improvement were made for impregnated diamond bit in raw material, formulation, mold and producing proceedings, and long-time and multi-level tests for bits were carried out.On the basis of the test data, the design parameters of the bit are determined, and a new type impregnated diamond bit suitable to deep hole drilling in hard rocks and strong abrasive formations has been developed.
