| 中文摘要:大庆油田深部地层岩石坚硬、研磨性强，运用常规手段钻进，单只钻头进尺少、寿命短且机械钻速较低。应用液力衡扭矩提速工具，有效解决了这些问题，显著提高了机械钻速和单只钻头的进尺。通过达深16井的现场试验证明，该工具能够使钻头的破岩方式在剪切的基础上附加机械冲击和高压水力脉冲，有效提高PDC钻头剪切岩层的效率，为深井提速提供了一种有效的手段。 |

| Abstract:Due to the hard and strong abrasive rocks in deep formation of Daqing oil field, the use of conventional drilling method with single bit means low run footage, short bit life and low ROP; these are effectively improved by the application of hydraulic constant torque rotary percussion tool. The field tests in Dashen 16 well prove that by the use of hydraulic constant torque rotary percussion tool, the rock breaking mode of bit can be attached with mechanical impact and high pressure hydraulic pulse on the basis of shearing, and the shearing efficiency of PDC bit can be greatly improved, which is an effective means to improve ROP of deep well drilling. |
