定向钻进工艺技术轨迹控制偏差分析

Analysis of Deviation in Trajectory Control in Directional Drilling Technology

结合ZDY系列煤矿履带式液压钻机应用定向钻进技术施工定向钻孔的使用情况,在定向钻孔轨迹设计、实钻轨迹控制、地层条件、随钻测量等几个方面对定向钻孔轨迹控制的偏差进行分析、总结,并针对如何采取减少轨迹控制偏差的措施进行了梳理,为定向钻孔设计、轨迹控制提供必要的参考依据。

Considering directional drilling with ZDY series coal-mine track hydraulic drill,the deviations in trajectory control of directional boreholes are analyzed and summarized in terms of design of directional drilling trajectory,control of actual drilling trajectory,stratigraphic conditions and survey along drilling etc. and measures to reduce the deviation in trajectory control are identified and checked. This provides necessary basis for design of directional drilling and trajectory control for reference.
