Description

防进油球座
一、技术领域:本实用新型涉及一种油田注水用井下工具,特别涉及一种防进油球座。
二、背景技术:目前,油田水井在注水过程中,常由于压力过大,导致周边油井的油进入到水井中,影响注水效果,但现在还没有能解决此问题的产品。
三、发明内容:本实用新型的目的就在于提供一种能防止油进入水井的防进油球座。本实用新型的技术解决方案是:所述防进油球座包括油管接箍,在油管接箍的下部连接有活塞套,在活塞套内腔中用销钉固定有活塞,在活塞的上方设置有防进油圆球,在防进油圆球的上方固定有上顶头;在活塞与活塞套之间设置有密封胶圈。本实用新型结构简单,成本低廉,使用方便,能有效防止油进入水井中,减轻了水井的污染,确保了良好的注水效果。
四、附图说明:图1是本实用新型实施例主视结构剖视示意图。
五、具体实施方式:参照附图,所述防进油球座包括油管接箍1,在油管接箍1的下部连接有活塞套2,在活塞套2内腔中用销钉6固定有活塞3,在活塞3的上方设置有防进油圆球4,在防进油圆球4的上方固定有上顶头5;在活塞3与活塞套2之间设置有密封胶圈7。
