| 摘 要： | 金山气田、龙凤山构造、长岭断陷等登娄库组以下深部地层可钻性差，研磨性强，导致钻头磨损严重，使用效率低。在对牙轮钻头、PDC钻头及孕镶金刚石钻头在高研磨性地层中的适应性进行细致和全面分析的基础上，提出了把PDC钻头机械钻速高和孕镶金刚石钻头进尺多的技术优势相结合的研制思路，开展PDC+孕镶复合式钻头设计。现场应用取得了良好的试验效果。提出了合理化的建议。

| Abstract: | Jinshan gas field is located in Longfengshan structure and Changling fault depression; in the deep formations below Denglouku, drillability is poor with strong abrasiveness, which causes serious bit wear and inefficient use. On the basis of detailed and overall analysis on the adaptability of cone bit, PDC bit and impregnated diamond bit in high abrasive formation, an idea was put forward that by combining the technical advantages of high ROP of PDC bit and long footage of impregnated diamond bit, the design was carried out on PDC impregnated composite bit. Good effect is received in field application of the bit and reasonable suggestions are also put forward. |
