Description

非金属连续油管打捞筒
技术领域
本发明涉及一种石油钻采打捞工具。
背景技术
在石油钻采作业中常发生有将如塑料管、橡胶管和钢丝骨架塑胶复合管等非金属连续油管断落在套管中的情况，使用已有打捞工具无法将其打捞出来。经中国专利文献检索和查阅有关资料尚未见有可打捞上述非金属连续油管打捞工具的报道。
发明内容
本发明的目的是：提供一种它可高效地打捞落在套管内的如塑料管、橡胶管和钢丝骨架塑胶复合管等非金属连续油管的打捞筒。
本发明的技术解决方案是：它由上接头、弹簧、筒体、弹簧座、定位套、卡瓦、引鞋和芯杆组成，所述筒体为上下两端口分别设有内螺纹和外螺纹的圆筒状体，筒体下端内壁为向下筒径逐渐缩小的锥形壁，所述卡瓦为外壁呈圆锥形，内壁设有卡牙，其上设有胀缩口的筒状体，所述芯杆为由上至下依次为大径段、小径段、中径段小径段和锥形头的杆状体，筒体的上下两端分别通过螺纹与上接头和引鞋相连，弹簧、弹簧座、定位套、卡瓦和芯杆位于筒体内，芯杆穿于弹簧座、定位套和卡瓦内，弹簧套在弹簧座上。
本发明的技术效果是：它可高效地打捞落在套管内的如塑料管、橡胶管和钢丝骨架塑胶复合管等非金属连续油管。
附图说明
图1为本发明实施例半剖图。
图2为本发明实施例芯杆结构图。
图3为本发明实施例筒体半剖图。
图4为本发明实施例卡瓦剖视图。
具体实施方式
如图1、图2、图3和图4所示，它由上接头1、弹簧2、筒体3、弹簧座4、定位套5、卡瓦6、引鞋7和芯杆8组成，所述筒体3为上下两端口分别设有内螺纹和外螺纹的圆筒状体，筒体3下端内壁为向下筒径逐渐缩小的锥形壁，所述卡瓦6为外壁为锥形壁，内壁设有卡牙9，其上设有胀缩口10的筒状体，所述芯杆8为由上至下依次为大径段、小径段、中径段小径段和锥形头的杆状体，筒体3的上下两端分别通过螺纹与上接头和引鞋相连，弹簧2、弹簧座4、定位套5、卡瓦6和芯杆8位于筒体3内，芯杆8穿于弹簧座4、定位套5和卡瓦6内，弹簧2套在弹簧座4上，所述卡牙9其上牙面与下牙面夹角是朝中心上方指向的螺纹状牙。
工作原理：在打捞操作中，打捞筒在套管内向下运动，当接触断落的非金属连续油管时，首先被引鞋7引入打捞筒，同时芯杆8也部分进入非金属连续油管中，继续施加轴向压力，非金属连续油管顶住卡瓦6，并使卡瓦6脱开筒体3的锥形壁在筒体内上行，当卡瓦6由芯杆8的中径段上行到芯杆8的小径段后非金属连续油管依次进入卡瓦6、定位套5和弹簧座4中，此时，上提钻杆，弹簧2下压卡瓦6，卡瓦6连同被其抱紧的非金属连续油管在筒体内相对向下运动，当卡瓦6由芯杆8的小径段下行到芯杆8的中径段时，卡瓦6和芯杆8夹紧非金属连续油管，至卡瓦6的锥形外壁与筒体3下端锥形内壁相贴合时夹咬力最大，继续上提钻杆实现打捞。
