| 摘 要： | 针对空心注水管柱有时在钢丝绳额定工作拉力范围内无法将配水器心子顺利捞出的问题,研制了液力助捞器。液力助捞器由打捞部分、支撑部分和密封部分组成,它采用液压力有效增加打捞动力,将打捞力提高至2 000 N/MPa,减轻了打捞车载荷。当配水器心子打捞不动时,液力助捞器可利用液压力剪断安全销,从井内安全起出,有效避免了录井钢丝绳断裂事故的发生。采用液力助捞器在胜利油田共计打捞心子189次,打捞成功率97.4%,液力助捞器起出率100%。 |

| Abstract: | When the hollow water injection string is used,the core of water flow regulator sometimes fails to be fished smoothly within the scope of the rated operating pull of steel wire rope.Considering the problem,the hydraulic fishing-assisted device was developed.The device consists of fishing part,supporting part and sealing part.The hydraulic force was adopted to increase the fishing force effectively,raising the fishing force to 2 000 N/MPa and thus reducing the fishing truck load.When the water regulator core cannot be fished,the hydraulic fishing-assisted device can use the hydraulic force to snip the safety pin and get the core out of the well safe and sound,thus effectively avoiding the appearance of the logging steel wire breaking.The device has finished fishing 189 times in Shengli Oilfield with a 97.4% success rate. |
