Abstract

本实用新型涉及一种油井液压洗井装置,属于油井洗井装置。包括井口大四通和油管挂,接头与油管挂螺纹连接,注液密封横管与该接头螺纹连接,该注液密封横管上有注液孔,该注液孔与接头内的环形液体流道相通,该环形液体流道的内壁短于外壁,内管与内壁螺纹连接,外管与外壁螺纹连接,内管与外管间有液体腔,接箍分别与两个外管螺纹连接。优点是结构新颖,利用现有井口的结构,通过注液密封横管从井口注入热水,把井内壁上的积蜡溶化,再用水洗掉,提高采油效率,有效地提高了产油量。

Description

油井液压洗井装置
技术领域
本实用新型属于油井洗井装置,尤其是指对油管内壁的结蜡的清洗。
背景技术
目前,油井在进行抽油作业一段时间后,油管壁结蜡严重,使采油量减少,给油田生产带来不便,现在并没有有效措施来处理结蜡这一问题。
发明内容
本实用新型提供一种油井液压洗井装置,以解决目前油管壁结蜡严重的问题。
本实用新型采取的技术方案是:包括井口大四通和油管挂,接头与油管挂螺纹连接,注液密封横管与该接头螺纹连接,该注液密封横管上有注液孔,该注液孔与接头内的环形液体流道相通,该环形液体流道的内壁短于外壁,内管与内壁螺纹连接,外管与外壁螺纹连接,内管与外管间有液体腔,接箍分别与两个外管螺纹连接。
本实用新型的优点是结构新颖,利用现有井口的结构,通过注液密封横管从井口注入热水,把井内壁上的积蜡溶化,再用水洗掉,提高采油效率,有效地提高了产油量。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
包括井口大四通1和油管挂2,接头3与油管挂2螺纹连接,注液密封横管4与该接头3螺纹连接,该注液密封横管4上有注液孔401,该注液孔与接头3内的环形液体流道301相通,该环形液体流道的内壁302短于外壁303,内管5与内壁螺纹连接,外管6与外壁螺纹连接,内管与外管间有液体腔8,接箍7分别与两个外管螺纹连接。
工作原理,通过注液密封横管从井口注入热水,经注液孔401进入接头3内的环形液体流道301,再继续进入内管与外管间的液体腔中,让热水把井内壁上的积蜡溶化,再用水洗掉。
