定向井井眼轨迹预测与控制技术

影响井眼轨迹的主要因素有地质特性、钻具组合结构、井眼轨迹几何形状、钻井工艺参数等。在钻井过程中，预测是控制的基础，如果没有精确的井眼轨迹参数预测，就不可能实现准确的井眼轨迹控制。通过实践经验和研究归纳总结出了一套井眼延伸方向预测的实用程序及井眼轨迹控制原则，供现场钻井施工技术人员参考。

Prediction and Control Technology of Wellbore Path of Directional Well

The main factors influencing the wellbore path include geologic characteristics,the bottom hole assembly,geometric pattern of the wellbore path,drilling parameters etc. During the drilling, prediction is the foundation of trajectory control. Without exact parameters prediction of the well path, wellbore path control can't be achieved. A set of practical programme for predicting the Wellbore extension direction and principles of wellbore path control have been obtained by practical experience and research.
