摘　　要：为提高套管捞油作业井的捞油效率,降低工人操作强度,提高经济效益,研制了一种高效套管捞油抽子。该抽子主要由芯轴、胶筒两部分组成,结构简单,过流通道大,钢骨架硫化的胶筒耐磨性大幅提高,同时也可连接内卸安全阀、加重杆使用,增强了安全性。投入现场应用后,年捞油5000t以上,捞油效率达到70%以上,应用前景广阔。In order to improve efficiency of oil bailing for casing salvaging operation in oil wells,reduce operating intensity of workers,improve economic efficiency,a kind of high efficient casing extractor was developed.The extractor was mainly composed of a mandrel and a rubber cylinder with simple structure big flow path,the abrasion resistance of rubber cylinder of steel skeleton vulcanization was improved greatly,but it also could be connected with unloading safety valve,weighting rod,by which its security was enhanced.Its field application shows that yearly oil bailing is more than 5000 t,its operation efficiency is above 70%,it has broad application prospects.
