| 中文摘要:为克服新疆油田重点探井二叠系地层岩石可钻性差、含砾地层严重粘滑振动，石炭系地层岩性致密、硬度高、研磨性强等难点，利用多维冲击振动结构实现大体积破岩、有效控制扭矩波动、抑制钻头粘滑振动，缩短钻井周期、降低钻井事故发生率。现场应用表明，多维冲击钻井技术能在可钻性差、深部硬岩地层实现高效破岩、钻井提速，有效地控制了钻井成本，值得在适宜地层进一步推广应用。 |

| Abstract:In order to overcome drilling difficulties such as the poor drillability and the severe stick-slip vibration in the bouldery formation of the Permian system, as well as the tight, hard and abrasive formation in the Carboniferous system in Xinjiang Oilfield, a multi-dimensional impact tool was used to achieve volumetric rock-crushing, effective control of torque fluctuations, suppression of stick-slip vibration; thus, cutting short of the drilling duration, and reduction of the drilling incidents. The field application shows that the multi-dimensional impact drilling technology can achieve high efficient rock breaking, and increase drilling rates in formation of poor drillability and deep hard rock formation, effectively reducing the drilling cost. It is worthy of further promotion and application in suitable formations. |
