摘　　要：常规钻井马达不能满足现有钻机需求,为此,开发了转速控制导向钻井技术。转速控制导向钻井技术结合了钻井马达和旋转导向系统2项常规技术特征,该技术充分利用了容积式马达和MWD 2项成熟技术,可实现三维井眼轨迹控制,显著缩短钻柱滑动时间,有利于提高钻井效率,改善井眼质量,降低钻井施工成本。阐述了传统马达技术和转速控制导向钻井技术的原理、优势与缺陷,介绍了转速控制导向钻井技术的现场应用效果,并针对其应用注意事项与发展趋势提出了建议。The conventional drilling motor cannot meet the needs of present drilling rigs. Therefore, rotation speed-controlled steering drilling technology was developed. The technology combines the features of drilling motor and rotary steering system. It makes full use of the mature technologies of positive displacement motor and MWD. It can achieve the three-dimensional control of hole trajectory and remarkably reduce the sliding time of drill string. This helps improve drilling efficiency, improve hole quality and reduce drilling construction cost. The paper first introduces the weakness of traditional motor technology and the principle, strength and weakness of rotation speed-controlled steering drilling technology. Then it analyzes the field application effect of the technology. Finally it offers some suggestions on the application cautions and development trend of the technology.
