| 中文摘要:X、Y井是部署在塔里木盆地顺北油田的2口勘探井，X井为钻井参数强化试验井，X井较Y井在实钻中更好地执行了钻井参数强化措施，三开5600~7500 m井段X井机械钻速较Y井提高了119%。对比分析，X井通过配置压力级别更高的地面设备，实钻实现了更高的排量和泵压，X、Y井的钻头冲击力分别为0.73~1.02 kN、0.61~0.85 kN，钻头水功率分别为6.79~11.38 kW、5.37~8.79 kW，机械比能为0.23~2.15 MPa、0.52~3.5 MPa。钻井参数强化的实验过程中，X井获得了更高的井底机械能量与水力能量以及更理想的破岩环境，其机械钻速明显高于Y井，符合钻井参数强化提速的预期。 |

| Abstract:X well and Y well were two exploration wells deployed in Shunbei Oilfield of Tarim Basin. X well was a field test well with enhanced drilling parameters. Compared with Y well， X well was drilled with better measures for enhanced drilling parameters in actual drilling. The mechanical drilling rate of X well in the third section from 5600 to 7500m was increased by 119% over that of Y well. Comparative analysis showed that X well was drilled with surface equipment with higher pressure； thus achieving higher volume and pump pressure in actual drilling. The bit impact forces for X well and Y well were 0.73 to 1.02kN and 0.61 to 0.85kN， bit hydraulic power 6.79 to 11.38kW and 5.37 to 8.79kW， and specific mechanical energy 0.23 to 2.15MPa and 0.52 to 3.5MPa respectively. In the experiment with enhanced drilling parameters， higher downhole mechanical energy and hydraulic energy were obtained in X well with better rock breaking environment. The mechanical ROP at the third drilling section was significantly higher than that in Y well， which met the expected ROP improvement with enhanced drilling parameters. |
