摘要
为了探索川型液压式悬挂器在承受较大轴向载荷时的工作情况，对川型液压式１７７．８ｍｍ单卡瓦和改型的１７７．８ｍｍ双卡瓦悬挂器，在承受１９６０ｋＮ轴向载荷作用时其工作及变形情况等进行了探索试验。文章论述了川型液压式１７７．８ｍｍ单、双卡瓦悬挂器能否承受１９６０ｋＮ的轴向载荷和在１９６０ｋＮ的轴向载荷作用下液缸、锥体是否变形；悬挂器剪钉、液缸剪钉剪切能否被剪断使液缸上移；倒扣头能否正常倒扣以及对上层套管的挤毁情况等。还介绍了川型液压式悬挂器在深并尾管固井中的现场应用情况。
The working and deforming conditions. suth as whether cylinder and cone deform, whether slips are cut off to make the cylinders upgoing. whether bask-off is normally functioned and the destruction of upper casings etc., of Sichuan hydraulic hanger with 177. 8mm single-slip and the remade one with 177. 8mm dual-cylinder and dual-slip are tested and expounded while bearing 1960 kN axial load.
