【摘要】 在石油完井作业中，固井水泥环受射孔弹聚能射流作用，局部会产生破裂现象．为了减轻射孔对水泥环的破坏，改善界面的密封胶结性能．本文利用Ｈｏｐｋｉｎｓｏｎ压杆对几种改性的水泥石进行了动态性能研究．文中给出了部分试验结果．更多还原

【Abstract】 Concrete rigs used for fixing oil-wells may be partially fractured under the action of the cumulative flow induced by perforative bullet during the oil-well operation. The dynamic behaviors of some modified concrete rock by the SHPB are studied in this paper to decrease the fracture of the concrete ring and to improve the hermetical cementing behaviors at the interface. Some exprimental results are presented.更多还原
