This paper outlines the-state-of-the-arts indrilling materials, drill bits,as well as drilling technology. Recently, many countries devote major efforts to developing synthetic diamond used in drilling industry with the forms of single crystal.polycrystalline mass and diamond composite,the latter has a good prospec. High efficiency, long life and low cost are the main trend in developing synthetic diamond drill bits. This peper discusses the bit performances required in drilling technology for further development. On the part of drilling technology,some applica tions,economic results, key problems and developing tendency of several drilling methods that widely used at present such as simultaneous drilling and casing, wireline core drilling, reverse circulation drilling, air core drilling, non-core drilling, chip drilling, vacuum drilling.,controlied directional and branch hole drilling etc. ard discussed. On the basis of comprehensive study on the main trend in drilling technology, drill bits and drilling materials, some viewpoints in the light of specific conditions in China are described in this paper.

本文论述了钻探磨料、钻头和钻进工艺三个方面的技术现状和技术水平。目前,许多国家都在大力发展人造金刚石,它在钻探上的应用有三种形式,即单晶体、复合体和聚晶体,后者较有发展前途。在钻头方面,总的发展趋势是研制高效、长寿、低成本的人造金刚石钻头。本文从钻进工艺发展的角度论述了对钻头性能的一系列要求。在钻进工艺方面,探讨了当前广泛应用的几种钻探方法的应用范周、经济效果、关健问题和今后发展。这些钻探方法包括跟臂钻进、绳索取心钻进、反循环取心钻进、空气吹井金刚石取心钻进、无岩心钻进、取岩屑钻进、真空取样钻进、定向钻进及分支孔钻进等。本文在综合分析了钻探磨料、钻头和钻进工艺主要发展趋势的基础上,结合我国的具体情况谈了个人的一些看法。

Two technical measures for diamond wireline core drilling into bad formations are introduced in this paper to solve two outstanding problems. The first one is that when drilling into the formations which collapse easy, leak water out, or sensitive to water , the diamond drill bits whose outer diameters are enlarged, are used in order to enlarge the ring - shaped interstice in hole, and decrease the resistance to drilling. The second one is to set elementary directed drilling holes, to improve the stability of the drilling tools at movement condition, and to use the wedgy pipe in order to set the bent hole right.
