井眼轨迹的快速高效导向控制是钻井工程领域的前沿科学课题。提出了地面旋转导向钻井的新思想。核心点是：（1）无井下测控元件。以现有顶驱钻井装置（或电动转盘）为基础，增设集成测控单元和预测控制器2个地面工作模块；（2）无间断连续制导。在旋转钻进时通过预测控制器，超前调慢钻柱在某预测方向区的速度，便可实现该预定方向的导向钻进。拟采用室内模拟测试、基本理论分析、应用研究等相结合的方式，探索钻柱系统在三维S型、L型、斜L型等典型弯曲井筒中的旋转运动特征，定量建立不同井筒形状、钻柱组合、钻进参数条件下钻柱动力响应特性的实验数学模型。同时，针对控制对象（钻柱与三维井筒系统）不确定性因素多、瞬变性强，以及信息的模糊性等特点，细分地面旋转导向控制的动作流程，应用人工智能中的专家控制系统，构建连续旋转钻柱地面导向钻井的预测控制模型。上述两方面的融合，将形成全新的地面旋转导向钻井控制的基础理论与技术体系。

The efficient steering control method of well trajectory is an important theoretical subject in drilling engineering field. A new method of surface rotary steerable drilling process is proposed. One of its core points is no downhole working elements. All the measuring elements, control mechanisms and actuators are on the ground, with good safety and high reliability. The other is non-stop continuous guidance. the direction control and direction adjustment of drill string can be realized automatically while continuous rotary drilling, which has good rapidity and high efficiency. The research method will be used by combining the indoor simulation test, basic theoretical analysis and applied technology. The mechanical behavior characteristics of the drill string system in typical curved wellbores such as three-dimensional S-type, L-type and inclined L-type are explored, and the experimental mathematical models of dynamic response characteristics of the whole drill string under different wellbore shapes, drill string combinations and drilling parameters are established quantitatively. At the same time, aiming at the uncertainties of the control object (drill string and three-dimensional wellbore system) and the incompleteness and fuzziness of the basic information obtained, the operation flows of ground rotary steering control are subdivided. By means of expert control system in artificial intelligence, the predictive control models of surface rotary steering control system are constructed. The integration of the above two research results will form a new basic theory and technical system of surface rotary steering drilling method.
