Abstract

本实用新型属石油工业专用的机械产品，主要用于井下作业采油。它采用等离子切割方法加工制造双层复合割缝筛管；它主要由内割缝管与外割缝管组合，并与下接头、上接头连接，上接头又与油管短节、上接箍连接构成。其主要有益效果是可下入油井的生产层面，进行挡砂，防止地层砂进入生产油管内，从而使油井正常生产，延长油井的使用寿命。

Description

等离子双层复合割缝筛管
一、技术领域：
本实用新型属石油工业专用的机械产品，主要用于井下作业采油。
二、技术背景：
在油田开发生产中，胶结疏松地层容易出砂，造成井下工具的损坏，泵心腐蚀，甚至造成停井。
三、发明内容：
本实用新型的目的是提供一种改进的等离子双层复合割缝筛管，解决防止地层砂进入生产油管内。本实用新型是采用等离子切割方法加工制造双层复合割缝筛管，它主要由内割缝管与外割缝管组合，并与下接头、上接头连接，再与上接头连接的还有油管短节及上接箍。
本实用新型的主要有益效果是可下入油井的生产层面，进行挡砂，防止地层砂进入生产油管内，从而使油井正常生产，并延长了油井的使用寿命。
四、附图说明：
如图是本实用新型的结构示意图。
注解：1、上接箍，2、油管短节，3、上接头，4、内割缝管，5、外割缝管，6、树脂复膜砂，7、下接头，
五、实施方式：
如图可知，本实用新型主要由内割缝管4与外割缝管5组合，在内割缝管4与外割缝管5之间空间内装有树脂复膜砂6，在该割缝管的下端安装下接头7，上端安装上接头3，上接头3又与油管短节2、上接箍1相连接构成。结构简单，使用方便。
