Novel drill special for well drilling

一种新型钻井专用钻头

Abstract

本发明公开了一种新型钻井专用钻头,包括钻头本体、连接公头和夹柄,钻头本体、连接公头和夹柄依次固定连接;钻头本体包括固定装置和钻削刀组,钻削刀组固定连接在固定装置上,钻削刀组包括若干个钻削刀片,每个钻削刀片上均匀设置有若干个凸点,固定装置为从上至下直径逐渐变小的圆台体结构,且最上部的半径与连接公头相同,一体成型,该固定装置的高度设置为0.5~0.8m;夹柄为倒立的子弹头结构,该子弹头与连接公头活动连接。其优点在于:本发明的新型钻井专用钻头,结构简单,通过设置连接公头,增加钻头钻取力度,钻削刀组配合固定装置,达到有效钻井的效果。
The invention discloses a novel drill special for well drilling. The novel drill special for well drilling comprises a drill body, a male connecting head and a clamp holder. The drill body, the male connecting head and the clamp holder are fixedly connected in sequence. The drill body comprises a fixing device and a drilling tool set. The drilling tool set is fixedly connected to the fixing device, the drilling tool set comprises a plurality of drilling blades, and each drilling blade is evenly provided with a plurality of salient points. The fixing device is of a circular truncated cone structure with the diameter being gradually decreased from top to bottom, the radius of the uppermost portion of the fixing device is the same as that of the male connecting head, integrated forming is achieved, and the height of the fixing device is 0.5-0.8 mm. The clamp holder is of an inverted bullet structure, and the bullet structure is movably connected with the male connecting head. The novel drill special for well drilling has the advantages that the structure is simple, the drilling force of the drill is increased through the arrangement of the male connecting head, the drilling tool set is matched with the fixing device, and the effect of effectively drilling wells can be achieved.
