无岩心钻进与取心钻进方法相比较，具有明显的优越性：可提高纯钻时间利用率，从而大幅度提高台效；提钻次数少，有利于孔壁稳定；有利于快速通过复杂地层；能缩短施工周期，降低钻探费用；能减轻工人体力劳动强度等。国外，对无岩心钻进十分重视，应用比较广泛，其中又以无岩心钻进配合气举反循环收集岩屑的方法已成为一种很重要的钻进方法。在我国，无岩心钻进还未得到广泛采用。但在某些老矿区地质情况已基本掌握的情况下，在那些根本不含勘探矿种的地层进行无岩心钻进完全是可行的。因此，应该重视无岩心钻进技术的研究。几年来，我们对φ66口径的无岩心钻进进行了一些研制工作，并在某矿区6级以内的红砂砾岩中（其间夹有7级）进行了2000多米的生产试验，取得了明显的技术经济效果。 Coreless drilling compared with coring drilling method, has obvious advantages: can improve the time utilization of pure diamond, thus greatly improve the Taiwan effect; less drilling times, is conducive to the stability of the hole wall; is conducive to rapid adoption of complex Strata; can shorten the construction cycle, reduce drilling costs; can reduce the labor intensity of workers and so on. Abroad, the non-core drilling attaches great importance to a wide range of applications, of which non-core drilling combined with gas lift reverse circulation collection of debris has become a very important method of drilling. In our country, coreless drilling has not been widely adopted. However, in the case of some old mining areas where the geological conditions have been basically mastered, it is entirely feasible to conduct coreless drilling in those formations that do not contain prospecting minerals at all. Therefore, we should pay attention to non-core drilling technology research. In recent years, we have done some research on the φ66-caliber coreless drilling and have conducted over 2000-meter production tests in red sand conglomerates within 6 levels of a mining area (with 7 levels in between), and have achieved remarkable technological achievements Economic effect.
