金刚石小口径钻进中的护孔堵漏问题，对我们三八机台来说是一个新课题，我们机台从成立到现在才二年多，而使用金刚石钻进还不到半年时间，水平低，经验少。金刚石小口径能不能用泥浆钻进？我们根据“实践第一”的精神，进行了试验。实践证明：不仅能用于金刚石钻进，而且是一种行之有效的简便护孔方法，初步取得小口径泥浆钻进的一点体会，简介如下。 Diamond small diameter drilling in the hole blocking problem, for our 38 machine is a new topic, we have been from the establishment of the machine more than two years ago, and the use of diamond drilling less than six months, the level of Low, less experienced. Diamond can not use small diameter drilling? We conducted the experiment according to the spirit of “practicing first”. Practice has proved that: not only can be used for diamond drilling, but also an effective method to facilitate simple hole, the initial access to a small hole drilling experience, is summarized as follows.
