摘要
在 139.7mm套管开窗侧钻井或加深钻井中 ,使用小尺寸单牙轮钻头具有明显的经济效益。主要介绍了小尺寸单牙轮钻头适用地层、结构特点、钻井参数优选及现场应用效果分析 。
Duringφ139 7 mm OD casing window sidetracking drilling or deepening drilling, using the smaller size, single cone bit has apparent economic benefit. This paper mainly introduces the appropriate formations, structure characteristics, optimum selection of drilling parameters and field applications of this smaller size, single cone bits, which has a certain effect on slim hole drilling in Zhongyuan Oilfield and other oilfields.
