| 摘 要： | 松辽盆地青山口组和嫩江组含油页岩系,夹有数十层白云岩透镜体或条带。在对该油页岩系进行钻探时,由于经常遇到硬度较大的白云岩层,使用普通的硬质合金钻头不仅进尺极其缓慢,而且钻头损坏严重,寿命短。为解决此钻探难题,研制开发具有高耐磨性和穿透能力强的钻头势在必行。为此,研发了尖齿状金刚石复合片钻头,并进行了现场钻进实验。结果表明,这种钻头在含白云岩层的油页岩地层钻进时,不仅钻进速度高,而且具有高耐磨性、寿命长,其综合技术经济指标远远优于常规硬质合金钻头。

| Abstract: | There are often dozens of layers of dolomite body or bands embedded in oil shale formation in Qingshankou and Nenjiang group at Song Liao basin.While drilling in above mentioned oil shale formations,dolomite interlayers with relatively high hardness were often encountered.If ordinary tungsten carbide cutter drilling bit was used,not only the footage was too slow in drilling process,but also the bit was seriously damaged.To solve above drilling problems,the development of new drilling bit with high wear resistance and high penetration ability was eagerly needed.In this paper,a new type of teeth-shaped PDC bit was designed and manufactured.Field drilling experiments using these teeth-shaped PDC bits were conducted and their drilling performances were compared with those of tungsten carbide bits.The results indicated that the new teeth-shaped PDC bit demonstrated high rate of penetration,high wear resistance and long service life while drilling in oil shale formation containing dolomite interlayer.The technical and economical index of teeth-shaped PDC drill bit was better than that of conventional tungsten carbide cutter bits. |
