摘要
获得地质资料的一种重要手段就是岩心钻探。随着科学技术及国民经济的发展,岩心钻探的深度和孔径不断提高,面对的地质条件越发复杂,因而岩心钻探发生事故的概率增大,事故种类增多,同时,事故复杂程度也日趋严重。文章基于此,对在不同地层情况下的矿产勘察钻探钻进方式进行分析。
One of the important means to obtain geological data is core drilling. With the development of science and technology and national economy, drilling depth and diameter increasing, facing the increasingly complex geological conditions, and thus increases the probability of core drilling accidents, accidents and accident types increased, the complexity becomes more and more serious. Based on this, the paper analyzes the drilling methods of mineral exploration and drilling in different formations.
