摘要:
为提高准噶尔盆地哈山区块火山岩地层机械钻速、增大单只钻头进尺、降低井眼失稳掉块卡钻风险，设计了刀翼式孕镶金刚石钻头。在分析地层岩石的力学特性的基础上，研发了新型胎体合金材料，以提高钻头研磨性；镶嵌孕镶切削块，以增强钻头破岩能力；优化设计了刀翼式孕镶金刚石钻头的结构和防卡流道，防止钻头卡死。研究发现，超细合金材料相互联结成键、牢固烧结，钻头胎体力学性能提高30%以上。刀翼式孕镶金刚石钻头配合高速大扭矩螺杆钻具在哈山101井火山岩地层进行了应用，单只钻头进尺增大4倍，机械钻速提高54.3%。研究结果表明，刀翼式孕镶金刚石钻头可以降低掉块卡钻风险，可实现火山岩地层安全高效钻进。
Abstract:In order to improve the ROP in the volcanic rock formation of the Hashan Area in Junggar Basin, increase the footage of single drill bit, and reduce the risks of wellbore instability and caving, the bit design for rapid drilling was carried out. The mechanical performance of the formation rock was analyzed by a full-scale coring indoor test. On this basis, a new matrix alloy material was developed to improve the grinding performance of the bit. Then, the impregnated cutting block was used to enhance the rock breaking ability, and the blade-type impregnated bit structure and the anti-sticking flow path were optimized. The caving falling into the oblique chip flute could be pushed upward to prevent the bit from being stuck. It was found that the ultra-fine alloy materials could be bonded to each other to form a firm adhesion, and the mechanical performance of bit matrix improved by more than 30%. The blade-type impregnated drill bit was used in the volcanic rock formation of Well Hashan 101 associated with a high-speed and high-torque screw power drill, the single bit footage was increased by 4 times and the ROP was increased by 54.3%. This technology also effectively reduced the risk of caving and sticking, and became an effective technical measure for safe and efficient drilling in such formations.
