摘要
针对大斜度定向井采用常规油管锚定工具存在锚定易松动、不易解卡等问题,研制了储能式可强制解卡油管锚定工具。该工具设计了弹性储能锁紧机构和强制解卡机构,能有效地解决锚定工具锚定松动以及大斜度井中锚定工具不易解卡的问题。40多井次现场应用表明,储能式可强制解卡油管锚定工具具有施工工艺简单、操作方便等特点,施工1次成功率100%,且锚定后不易松动,易于解卡,是一种适用于大斜度定向井理想的油管锚定工具。
The ordinary tubing anchoring tool used in large-deviation directional well has such problems as loose anchoring and difficult releasing. Therefore, a kind of energy-storage forcible releasing tubing anchoring tool is developed. The elastic energy-storage latching mechanism and forcible releasing mechanism are designed in the tool for effectively solving the above problems. The field application in more than 40 wells indicates that the tool features simple technique and convenient operation with 100% of success rate. The tool, after anchored, is difficult to be loosened, but easy to be released. It is an ideal tubing anchoring tool for large-deviation directional well.
