摘要: 通过对底部钻具组合受力变形分析、地层力的计算及井壁变形影响分析,提出了钻具结构集度的概念和计算方法;在分析影响井眼轨迹主要因素的基础上,用数理统计的方法,建立了井眼轨迹预测模式,完善了井眼轨迹预测控制技术。经现场应用,收效显著。Abstract: The concept and calculating method are suggested based on the deformation analysis of BHA, calculations of formation forces, and analysis of wal1 deformation effects. Well path prediction models were established and the prediction and control techniques were improved by using mathematical statistics on the basis of analytical results of main factors which affected the path.
