摘要
Φ311mm垂直钻井系统是克拉玛依钻井工艺研究院历时多年研制成功的井下工具,是机、电、液一体化的井下智能钻井系统。该工具可实现在高陡地层,特别是在山前构造带地层的防斜打快技术。目前,该系统已在新疆油田试验两口井次,并获成功。试验结果表明,该系统各项指标均达到设计要求,满足了闭环控制的设计要求,具有广阔的应用前景。
311mm Automatic Vertical Drilling System(311 AVDS)is a new type downhole inTelligent drilling system,which can make a wellbore automatical uprightness.There're some advantages in 311 AVDS,such as power generation,downhole closed loop control,data transmission in real time and its analysis,etc.The 311 AVDS can make the bit weight liberated and rate of penetration boosted greatly.And the 311 AVDS has been applied successfully in Xinjiang Oilfield.The application results showed that 311 AVDS system could meet the design requirement of closed loop control,had good application prospects.
