介绍了胜利油田埕北６Ｂ丛式井组６口定向井的工程设计， 并分析了其钻井难点及对策， 详细述叙了利用导向钻井技术钻定向段及稳斜段的技术措施。６口定向井平均钻井周期４．３１ｄ， 平均机械钻速３２．３６ｍ ／ｈ， 与该区块１９９７年用常规钻井技术所钻井眼相比， 机械钻速明显提高， 钻井成本明显降低， 经济效益显著。
The engineering design of six directional wells in Taobei 6B cluster well group in Shengli Oilfield is introduced. The difficulties and countermeasures of drilling well are analyzed. The technical measures of drilling directional section and steady inclined section using pilot drilling technology are described in detail. The average drilling cycle of 6 directional wells was 4.31d, and the average penetration rate was 32.36m / h. Compared with the borehole drilled by conventional drilling technology in this block in 1997, the ROP was obviously increased, the drilling cost was obviously reduced, and the economic benefit Significant.
