摘要
随钻测斜仪在钻井现场中应用相当广泛。文章首先对随钻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了随钻仪传感器输出数据，同时对传感器输出数据的数学修正进行了分析。这样可以使仪器使用者了解仪器原理，进行准确的测量。在现场中利用随钻仪的特点，或只用高边工具面、或只用磁性工具面完成定向工作。
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.
