井眼轨迹曲线的计算机描绘

Delineation of Borehole Trajectory Curve by Using Computer

阐述一种井眼轨迹的描绘方法即柱面图描绘法。这种方法可使测井人员更加直观、有效地根据测井资料（井外角、方位角及测量并深）描绘井眼轨迹曲线。井眼坐标的计算方法采用平均角法，该方法计算简单、准确度高。往面图描绘方法应用于测科仪数据处理软件，可在计算机屏幕上获得井眼轨迹的水平投影留和垂直剖面图，为钻井工程技术人员合理地设计井下钻具结构，为定向井的设计和施工提供依据。实验结果表明，井眼轨迹往面图描绘方法简单、曲线直观，受到国内油田的普遍欢迎。

The avemp angle methed is used to calculatethe sPace peihon of measmement Point. ItS calculation is stwle and its precision is high. Using the methed can drawthe horizontal projection and vethcal profile graphs of harehole trajectory- The experiment results show that the method issimple and has high efficiency.
