随钻测斜系统的数学模型分析及应用

随钻测斜仪在钻井现场中应用相当广泛。文章首先对随外事测斜仪所测参数进行定义，包括井斜角、方位角、高边工具面角及磁性工具面角，然后分析了一系列确定井眼参数的数学模型。这些数学模型在计算中利用随钻仪传感器数据，同时对传感器输出数据的数学修正进行了分析。

The Analysis and Application of the Mathematical Model on MWD

Angle measuring MWD tool is widely used in field well drilling. Firstly,this paper gave out definationsof parameters, the well inclination, azimuth angle, high-edge face angle of the drlling tool and magnetic face angle for the analysis of the MWD tool. Then a series of mathematical models on determining bore-hole pa-rameters were studied. In the computation of these models the output data of MWD transducer were uti-lized and their corrections were analysized. The studies here will benefit the user not only in the principle of the tool but also a better understanding of the precision of the tool as to have a accurate measurement and fully utilize the tool.
