摘　　要：LZ系列连续造斜器作为一种定向造斜的工具,广泛应用于石油领域。而在小口径固体矿产钻探,则缺乏相应的成熟技术,一直未能较大范围的推广。针对兰陵铁矿矿区的地层情况与其造成钻孔普遍偏斜的原因,结合矿区连续造斜器的应用,介绍了LZ-75型连续造斜器的工作原理和2种定向方法,以及一些使用心得。LZ series of continuous whipstock is a deflection-making tool applied in petroleum domain, but which is not pop- ularized in a wider scope for small diameter drilling of solid minerals being lack of the mature corresponding technology. According to the formation conditions in Lanling iron mine area and the causes of common phenomenon of borehole deflec- tion, the paper introduced the working principles of LZ -73 continuous whipstock and 2 kinds of direction methods based on the application of whipstock in the mine and some experiences.
