MEASURING DRILLSTEM LOADING AND BEHAVIOR |
摘要 |
A drillstem loading and behavior measurement method and system includes spaced apart subs disposed at the upper end of the drillstem and connected to each other and to a power or conventional swivel and having strain gages and accelerometers mounted thereon in such a way as to measure axial loading, axial vibration, torsional loading, torsional vibration and bending modes of the drillstem during operation. Accelerometers are mounted on respective ones of the subs at a distance from each other sufficient to determine vibration waveforms in axial, torsional and bending modes. |
