摘要
Abstract
The advantages and disadvantages of directional drilling and rotary drilling are analyzed from the perspective of the drilling process,at the same time,and we analyzed the deviation principle and influence factor of the rotary drilling.The construction technology and implementation steps of the nearly horizontal long borehole trajectory control are proposed.Using directional drilling technology to adjust the drilling trajectory,using rotary drilling to speed up the drilling efficiency,the measurement system of directional drilling is used to measure the trajectory of rotary stage and predict strata deflection law of rotary drilling to guide subsequent rotary drilling.Field practice shows that the effect of mixed drilling combined directional drilling and rotary drilling is significant,which not only ensures the borehole trajectory precision,but also accelerates the drilling speed,and deepens drilling footage.关键词
