摘要
针对直井中使用扶正器对抽油杆柱扶正存在的问题,给出确定扶正器扶正范围的计算公式,并推导出防止抽油杆柱和油管柱两者弯曲变形的扶正间距计算公式。为方便使用者进行扶正设计,还给出扶正间距选择版图和计算程序。
In the light of the problems present in rod string centering in straight holes, the extent of actual control of a centralizer is discussed, and, in view of preventing both the rod string and the tubing string from buckling, a formula for selecting the optimum space between each two centralizers is worked out. Chart and computing program are given for the convenience of space selecting.
