一、问题的提出我国金刚石钻进是从六十年代初开始的，由全国几台钻机发展到目前地质系统就开动500台以上；由用天然表镶钻头发展到目前大量采用天然和人造金刚石孕镶钻头。各地在开始采用金刚石钻进时，一般都选择条件比较好的地层，以便取得经验，进而推广。以往研究成功的63~#钻头胎体配方在大部分中硬一硬地层中能够适应并获得优良效果，因而在全国普遍采用，但随着金刚石钻进的发展，遇到地层类型越来越多、条件越来越复杂，较单一的胎体配方和少数的钻头品种已远远不适应金刚石钻进发展要求。要打开金刚石钻进的新局面，就必须解决“拦路虎”地层的钻进问题，必须重视研究这些地层中钻进的钻头品种和钻进工艺问题。“打滑”地层便是金刚石钻进最艰巨的“拦路虎”地层之一。
First, the issue raised Diamond drilling is from the beginning of the sixties of the country, the country by several drilling rig development to the current geological system on more than 500 units; from natural table boring drill development to the present extensive use of natural and synthetic diamond Inset drill bits. When diamond drilling is started all over the world, generally, the stratum with better conditions is chosen so as to gain experience and further promotion. The 63 ~ # drill bit matrix successfully studied in the past can adapt and obtain excellent results in most of the hard and hard formations and is therefore widely used in the country, but as the diamond drilling progresses, more and more types of formations are encountered , The conditions are more and more complex, more than a single carcass formulations and a small number of drill varieties have fallen far into the development of diamond drilling requirements. To open the new situation of diamond drilling, we must solve the “stumbling block” formation drilling problems, we must pay attention to drilling in these formations bit varieties and drilling technology issues. The “slippery” formation is one of the most formidable “stumbling block” diamonds to drill into.
