摘　　要：收集了大港油田196个井段的井史资料和11口井的65000点井径数据。通过对这些资料进行分析研究，总结了下部钻具组合、区域地质条件、井斜角、并送扩大等因素对方位漂移的影响。对于收集到的地层分层参数，提出了用拟合法求地层倾角和倾向的公式，并给出了算倒。从实钻资料总结出的一些规律，对定向钻井的方位控制有很好的指导作用。The paper collects the data of drilling historyof 196 well-segments and the data of 65000 wellbore diam-eter in 11 wells in Dagang oil field. By analysis and con-trast of these data, the paper summarizes effects on az-imuth walk of such factors as BHA design, formation conditions, inclination angle, wellbore enlargement and so on-For formation parameters collected, the paper presentsthat dip and dip azimuth of formation can be computed byinitiation method and also gives some examples. Theselaws from actural drilli ng history have a good role in guid-ing azimuth control of directional drilling.
