中文摘要:钻探工程中使用钻头的类型很多。近年来,金刚石复合片(PDC)钻头得到了广泛的利用,取得了很好的技术经济效果。但是,对于PDC钻头设计的研究工作不够充分,需要进一步加强,以便取得更好的技术经济效果和更好地推广使用。俄罗斯钻探工作者在这方面做了很多研发工作,获得多项发明专利,取得了较好的成果。以其中3个专利为切入点进行分析研究,包括切削型双节翼片式钻头、稳定型钻头、PDC螺旋状排列钻头。这些成果有较好的使用价值和推广前景,建议我国对此进行研究和试验。 |

Abstract:There a lot of types of drill bit, used in geological exploration. In recent years PDC (Polycrystalline Diamond Compact) bits have been used widely and good technical and economical results obtained. However it is not enough well to design the bits and necessary to strengthen this work in order to get better results and wider application. In this field Russian drillers have made many works,obtained invention patents and got better results. Now the results are analyzed and researched, taking the three patents of them as researching objects, including cutting type double wing blade drill bit, stable drill bit, PDC spiral arrangement drill bit. The results may be have some reference value for us and should attract our attention. |
