摘要
为满足塔河油田高压油气井措施作业要求,解决永久式封隔器打捞难题,对永久封的结构特点、常规处理工艺及打捞难点进行剖析,创新打捞思路;对打捞工具进行优选和改造,形成具有塔河油田特色的永久封打捞配套技术与专用工具,提高了作业效率与成功率。现场应用结果表明:该打捞工艺能够满足塔河油田现场打捞需求,适用于奥陶系恶性漏失地层,具有一定的"普适性"推广价值。
This paper analyzes the structural features of the permanent packer, conventional treatment process and fishing difficulty. It also optimizes and upgrades the fishing tool to form a special permanent packer fishing technology and special tool for Tahe Oilfield and increase working efficiency and success rate. Field response shows that this fishing technology meets the requirement of field fishing operation in Tahe Oilfield and applies to Ordovician severe leak formation.
