Abstract

一种多相分离自洁式抽吸装置,是由外管(6),不锈钢丝缠绕式筛管(4),螺旋叶片(5),上下接头(3)、(8)构成,其特征是:不锈钢丝缠绕式筛管(4)用螺纹联结在上接头(3)的内孔,不锈钢螺旋叶片(5)固定在不锈钢丝缠绕式筛管(4)的外圆上,再在螺旋叶片(5)的外圆套上外管(6),所述外管(6)的上部钻有4个排气斜孔。该装置除具有抽吸功能外还具有防砂、防气的功能,从而提高抽吸效率,延长抽油泵的使用寿命,增加采油经济效益。

Description

多相分离自洁式抽吸装置
技术领域
本实用新型涉及油田采油领域所用的抽吸装置,尤其是自洁式抽吸装置。 
背景技术
在采油领域中,采油抽吸装置是采油的重要设备。抽吸装置主要是解决抽油泵抽油问题,现在油田已进入中后期,多为含水、含气、含蜡、含沙量大的油井,因此给抽油造成一定的困难,时间一长,抽油泵就会堵塞,从而直接影响油井的生产。 
发明内容
为了克服现有抽吸装置的上述缺陷,本实用新型提供一种多相分离自洁式抽吸装置,该自洁式装置不仅能够自动清洁,而且具有防砂防气的功能,使用寿命长、节约采油成本的特点。 
本实用新型解决其技术问题所采用的技术方案是:一种多相分离自洁式抽吸装置,是由上部钻有若干通孔的外管6,不锈钢丝缠绕式筛管4,螺旋叶片5,上下接头3、8构成,不锈钢丝缠绕式筛管4用螺纹联结在上接头3的内孔,不锈钢螺旋叶片5固定在不锈钢丝缠绕式筛管4的外圆上,再在螺旋叶片5的外圆套上外管6。外管6的上部钻有4个排气斜孔。 
多相分离自洁式抽吸装置采用流体力学原理设计制造,油液由该总成外管小孔进入本装置内,经过螺旋片实现气、砂、液自动分离,分离出的气体由上部四斜孔排出,液体经螺旋片及绕丝缝隙进入内部芯管,同时旋转的油液还可以把绕丝管壁上的残存的砂子冲刷掉,达到自我清洗的目的。 
本实用新型的有益效果是:多相分离自洁式抽吸装置除具有抽吸功能外还具有防砂、防气的功能,从而提高抽吸效率,延长抽油装置的使用寿命,增加采油经济效益。 
附图说明
下面结合附图和实施例对本实用新型作进一步说明。 
图1是本实用新型的结构原理图。 
在图中:1、抽油泵,2、油管,3、上接头,4、不锈钢丝缠绕式筛管,5、螺旋叶片,6、外管,7、多相分离自洁式抽吸装置,8、下接头,9、尾管,10、堵头。 
具体实施方式
该装置主要由抽油泵总成和多相分离自洁式总成两部分组成,下井先将装有堵头的10-20根尾管先下放到井内,然后顺序连接多相分离自洁式抽吸装置,接着串联若干根油管,再串联抽油泵总成、油管直至达到油管柱总长。该多相分离自洁式总成采用流体力学原理设计制造,与抽油泵总成连接后下入油井中,介质由该装置外管小孔进入本装置内,实现气、砂、液自动分离,分离出的气体由上部4斜孔排入油套管环空;分离出的砂子沉入尾管中;分离后油液从内部芯管进入抽油泵泵筒内;液体经螺旋片进入内部芯管时,还可起到自我清洗的作用,把绕丝管壁上的残存的砂子冲刷掉。
