摘　　要：依据微分几何原理,得到了用以描述井眼轨道空间挠曲形态诸参数的精确计算公式,阐述了相应参数之间的依赖关系,并对挠曲参数的各种计算方法进行了综合分析和评价。现场验证表明,这些理论具有重要的意义和实用价值。The research on the shape of the space curve of bit trajectory is the basis of thereal-time inspection and analysis of borehole trajectory, it is also an essential prerequi-site to the frictional force calculating and the bit trajectory predicting and controlling.According to differential geometry, the exact equations for the parameters to describethe trajectory deflection form are derived in this paper,and the dependable relationshipamong the parameters is elaborated. Every calculating method for each parameter isanalysed and evaluated synthetically. Oil field tests show that these theories are of greatsignificance and practical value.
