通过“定向控制、最佳水平井段、滑动隐成本、钻头导向、动力改进”等几个方面分别介绍了各公司推出的旋转可转向系统及其使用效果 ;并详细论述了使用常规马达钻井和使用旋转可转向系统钻井的优缺点及其在机械钻速和钻井费用上的巨大差别 ;同时说明了旋转可转向系统可大大提高定向井、延伸井、轮廓设计井的钻井特性和井的质量
The rotating steerable systems introduced by various companies and their effects are introduced respectively through “directional control, optimal horizontal well section, sliding hidden cost, bit orientation, power improvement” and so on. In addition, the application of conventional motor drilling and The advantages and disadvantages of drilling with steerable steerable systems and their great differences in ROP and drilling costs are also illustrated. In the meantime, it is shown that the rotational steerable system can greatly improve the drilling characteristics and well quality of directional wells, extension wells and contouring wells
