- 摘要:
- 南海西部北部湾盆地钻井作业中,一开使用铣齿牙轮钻头和PDC钻头,需要2趟钻才能钻至涠洲组一段地层满足下表层套管需求。为解决钻井效率低、成本高问题,通过对镶齿牙轮钻头设计优化,研发出了适应北部湾盆地新近系地层区块的强攻击型镶齿牙轮钻头,实现了1只钻头、1趟钻钻进至涠洲组一段地层,所形成的钻头设计关键技术在北部湾盆地钻井作业中得到普遍应用,大幅提高了钻井效率。研究成果可为软硬交错地层、高含砂砾岩地层钻头设计及选型提供借鉴。
In the drilling operation in the Beibu Gulf Basin in the west of the South China Sea, the first spud uses milling cone bit and PDC bit, which requires two trips to drill to the first formation of Weizhou formation to meet the needs of lower surface casing. In order to solve the problems of low drilling efficiency and high capital cost, through the optimization of the design of the inserted cone bit, a strong-attack inserted cone bit suitable for this block is developed, which realizes one bit and one drill to the formation of Weizhou formation. The key technology of bit design is widely used in the drilling operation in Beibu Gulf Basin, which improves the drilling efficiency significantly. The research results can provide reference for the design and selection of drill bits for loose and hard interlocking formation and sandy conglomerate formation.
