查询词典 well drilling

The vibration of drilling string in horizontal well is closely related with the overall length of the drill string and structural shape. In this paper ,a mechanical model of longitudinal vibration of drill strings is established by studying the overall drilling string,seeing a hole as arbitrary bending curve in three-dimensional space.
