定向钻进过程的智能化控制技术研究与应用

Research and Application of Intelligent Control in the Process of Directional Drilling

在非开挖地下管线定向钻进过程中,优选钻头的钻进参数是实现钻进自动化与智能化的关键问题.通过对工程所在地基本地质条件、已有地下管线种类及分布特征的研究建立起定向钻进智能控制知识信息库,可以为钻机的智能钻进提供知识、逻辑、数据参数等数字化基础信息,引导钻机在具体的土层特征、钻进深度、钻进角度、钻速、推力、扭矩、钻进液状态等参数控制下,实现非开地下挖管线定向钻进的计算机智能化控制,有效规避施工风险,提高非开挖智能化定向钻进技术的经济效益和社会效益.

In the process of directional drilling of underground pipeline,optimizing the drilling parameters of a bit is the key issues to achieve drilling automation and intelligentialization.A data base should be first established,based on the study of the engineering location＇s geological conditios,the underground pipeline types and distribution.It can provide different types of basic digital data,like knowledge,logic and number parameters.Under the control of actual soil characteristics,drilling depth,angles,speed,pushing force and the state of drilling liquid,risks of construction can be effectively avoided and the economic and social benefits of underground pipeline directional drilling can be dramatically raised.
