Development and Testing of a New Type of Diamond-Impregnated Bits
-
摘要: PDC钻头不适用于深部砂泥岩互层,而采用牙轮钻头钻进该类地层,存在钻头寿命短、进尺少、机械钻速低等问题,为解决该问题,研制了新型孕镶金刚石钻头。首先通过钻进试验,确定金刚石浓度为80%。该金刚石由40/45目和70/80目两种粒度组成,两种粒度的金刚石分别占金刚石总量的65%和35%,其中40/45目金刚石起提高机械钻速的作用,70/80目金刚石起增强耐磨性、延长钻头寿命的作用。接着通过测试不同配方基体的力学性能,优选出了碳化钨含量24%、其他骨架料22%、粘接剂54%的D-6号基体配方。最后设计了"B"形冠部、140°内锥角、20°后倾角、心部7颗φ16.0 mm优质PDC复合片防掏心结构的新型孕镶金刚石钻头。该钻头在元坝气田进行了试验,结果表明,在相同井段单只钻头的进尺与其他钻头相比平均增加了484.7%,机械钻速平均提高了150.8%。这表明,新型孕镶金刚石钻头为深部砂泥岩互层提供了一种新的高效破岩工具。Abstract: New type of diamond-impregnated bits were developed to solve the problem that PDC bit is not compatible and cone bits have shorter drilling life, less footage and lower ROP in thin sand shale interbed. Diamond concentration was determined to be 80% by drilling tests. Two formulae of diamond granularity were adopted, with 40/45-mesh coarse grain diamond taking up 65%, which was used to crush rocks to improve ROP, and 70/80-mesh fine grain diamond accounting for 35%, which was used to improve the abrasive resistance and service life of drill bits. By testing the mechanic performances of different formula matrices, the D-6 matrix formula was selected, in which tungsten carbide took up 24%, skeleton material 22%, and adhesive 54%. A new type of anti-hollow, high quality structured diamond-impregnated bits were developed ,which had "B"-shaped crown, and 140° inner cone angle, 20° back dip angle, and seven φ16mm diamond grains. The bits were tested in the Yuanba Gas Field. The field test result showed that the average footage was increased by 484.7% and the average rate of penetration was increased by 150.8% compared with other bits in same well sections. The successfully developed new type diamond-impregnated bits are new rock crushing tools with high efficiency for drilling in deep thin sand-shale interbeds.
