| 中文摘要:利用地面仪表显示的井底数据来指导和优化钻井工艺和操作流程是钻井工程常采用的做法。然而有些井底数据与井底的实际情况有较大差异，井越深，这种差异越大，特别是超深井钻进时更是如此，最终会影响钻井技术经济指标的提高。因此，如何准确测量井底参数并传输到地表进而对这些参数进行相应调控是深井安全高效钻进急需解决的关键难题之一。本文介绍了俄罗斯研究人员提出的深井井底参数自动遥测和控制系统，对井底钻井液压力、井眼方位角、顶角和钻头轴载等井底参数测量、组合传输和自动控制细节进行了分析。这些自动测量和控制系统的设计思想和实施方案对今后我国深井、超深井特别是计划中的13000 m特深井钻进具有一定的参考价值和借鉴意义，值得我们关注。 |

| Abstract:Drilling parameters and operations are often guided by data shown at surface devices during drilling process. However， some of these data are different from real downhole parameters. The deeper the borehole， the bigger the difference; and it is true with deep drilling， particularly super deep drilling. As a result， it will influence improvement of technical and economical indexes of well drilling. Here we introduce the research results from Russian peers who deeply investigated on remote measurement and automatic control system of borehole bottom parameters such as drilling fluid pressure， azimuth， inclination， axial weight on bit. They also proposed some frameworks on how to perform these measurements and control operations. In China， deep earth exploration strategy has been initiated and a 13000m ultra-deep well is under planning. The design approach and execution plan for these systems discussed here can provide beneficial reference for downhole parameter measurement and automatic control during super deep well drilling of China in the near future. |
