Abstract: Azimuthal comparison method of 3-D design of directional well indicates that deflection tools can quantitively design and calculate each of the compensation values of tool face azimuth per l0m's penetration.The designing curve coincides with the actual well track.The method solves the problem that the field construction differs from the lateral and the current 3-D theory design,with higher accuraccy of the well bore designing data.The actual application has been completed in 5 segments of 2 wells,jianghan Oil Field.The method can guide the field construction.

Key words: directional well, 3-D, design, azimuth, theory

摘要： 定向井实用三级设计─方位比较法,给出了造斜工具每钻进10m进行一次装置角补偿值定量设计与计算方法,设计曲线与实钻轨迹相符合,解决了平面和现行三维理论设计与实际施工工艺不一致的问题,设计的井身数据精度高,现场应用效果好,通过江汉油田2口井5个井段的实际应用,可以指导实际施工.
