自动垂直钻井工具纠斜控制实验研究

Experiment Research on Correcting Deviation Control of Vertical Drilling Device

采用无模型自适应方法避免对地层各项参数及钻探纠斜过程中不可预知环节的系统辨识,仅以控制目标作为调整对象,实现了对纠斜力的控制。并设计模拟试验,对比分析了传感器倾角变化与MFA控制算法响应的纠斜力变化的规律。讨论了试验中存在的不足,并提出了有待进一步研究的问题。

The method based on model - free adaptive control can avoid system identification, such as parame- ters of formations and unpredicable parts in drilling, which only takes the control target for the adjustment ob- ject to realize the correcting deviation force control. This paper designs the simulation experiment and analyzes the relationship between the sensor＇ s inclination angle change and the MFA sontrol counting response of the correcting drviation force. This paper also discusses the shortage in the experiments and provides the problems to be solved.
