| 摘 要： | 为分析随钻测量仪MWD在实际测量中的独立误差源,根据大地坐标系到仪器坐标系的转换对MWD的测量原理进行了系统推导,得出测量井眼轨迹的基本参数,进而结合典型测量仪器的4项独立误差源及MWD进行井眼轨迹测量的特点,在性质和量度方面详细分析了MWD的各项独立误差源,并通过对独立误差源进行分析修正,得出MWD现场应用的优点。

| Abstract: | MWD independent error sources are analyzed by converting from earth coordinates to instrument coordinates and inferring MWD measurement principle.The basic parameters of measuring points are derived.Each independent error source of MWD has been analyzed in terms of nature and magnitude by taking account of the four error sources of typical measuring instrument.The advantages of MWD can be brought into full play in field application by modifying independent error sources. |
