| description | The invention discloses a method for calculating the axial distance of a cutting opening of a multi-layer eccentric sleeve and the abrasion length of a blade, and the method can calculate the vertical distance of the cutting opening of the multi-layer eccentric sleeve and the shortest abrasion length of the blade required for cutting off the multi-layer eccentric sleeve, so that whether the multi-layer eccentric sleeve is successfully cut off or not can be effectively calculated and judged. The method has important guiding significance for offshore well repair operation and well abandoning operation.
本发明公开了一种多层偏心套管切割割口轴向距及刀片磨损长度的计算方法，本方法可以计算出多层偏心套管割口的垂向距，以及多层偏心套管被割断所需的最短刀片磨损长度，依此可以有效地计算判断多层偏心套管是否被成功割断，对于海上修井作业、弃井作业具有重要指导意义。 |
