井口套管密封防盗丝堵
技术领域
本实用新型涉及一种井口套管密封防盗丝堵,属油田采油树套管气密封装置技术领域。
背景技术
目前,油田油气井一般都是野外生产,现有的套管丝堵多为外六方形,不法份子卸开井口套管丝堵进行盗取天然气现象时有发生,给油田带来了经济损失。ZL200720157299.7公开了一种防盗丝堵,由丝堵和六方操作头组成,丝堵头内部设有一圆形盲孔,六方操作头的端部设有与丝堵头的盲孔对应的圆柱形,圆柱形与六方同轴,盲孔与圆柱形之间设有沿圆周方向的定位装置,有一定的防盗效果。
实用新型内容
本实用新型的目的是为防止不法份子盗取油田井口油气,提供一种井口套管密封防盗丝堵。
本实用新型的本体为下部封口的管状体,外管壁为螺纹,本体下端面上设有凸台,在其内管壁上开有卡槽。
利用本实用新型封堵井口,不仅起到了对井口套管气封堵的作用,且防盗性能好,只有使用非常规专用工具,才可安装或拆卸,避免人为卸开丝堵盗窃油气现象发生。
附图说明
图1是本实用新型的主视图;
图2是本实用新型专用工具结构示意图。
1-本体、2-卡槽、3-凸台。
具体实施方式
由图1可知,本实用新型的本体1为下部封口的管状体,外管壁为螺纹,本体1下端面上设有凸台3,在其内管壁上开有卡槽2。
上述防盗丝堵的凸台3可以为圆柱形或三角形,只有用图2所示的专用工具才可拆卸。
上述专用工具的顶端凹槽插入凸台3,侧端插入卡槽2,旋转专用工具既可安装或拆卸丝堵。
