摘　　要：传统的高陡地层钻井防斜纠斜方法无法经济、高效地解决在大倾角、陡构造、断层、地应力异常等地层的防斜打快问题。通过对垂直钻井系统的结构、工作原理及现场应用等情况分析,认为311垂直钻井系统是一种集机电液一体化的井下智能自动垂直钻井系统。应用结果表明,该系统各项指标均达到设计要求,满足了高陡易斜难钻地层防斜打快的技术要求。Some traditional deviation-control drilling methods for high-steep formations cannot solve economically and efficiently the problems of both deviation control and drilling fast in formations featured by high dip angle, steep structure, fault and abnormal ground stress. According to the analysis on the structure, operational principle and field application of vertical drilling system, Φ311 is considered as a downhole intelligent and automatic system with mechatronics and hydraulics integration. Application results show that all indices of the system meet the requirements of design and deviation control and drilling fast of high-steep formations.
