Abstract

本实用新型公开了一种自控温油井电伴热带,包括有数个金属内芯,每个金属内芯分别由一根金属导线组成,或由数根金属导线绞合组成;所述的数个金属内芯外依次包覆有导电层、绝缘层、屏蔽层和外护套。本实用新型具有经济性,也便于控制,且不会污染原油。

Description

自控温油井电伴热带
技术领域
本实用新型涉及伴热电缆领域,具体涉及一种自控温油井电伴热带。
背景技术
原油在开采时,当原油从油层通过油管到达集输泵站,由于热量损失,使原油温度低于灵界流动温度,这会导致蜡的析出沉淀,粘度突增,增加流动压力,从而不能顺利开采。
实用新型内容
本实用新型要解决的技术问题是提供一种自控温油井电伴热带,其具有经济性,也便于控制,且不会污染原油。
本实用新型的技术方案如下:
一种自控温油井电伴热带,包括有数个金属内芯,每个金属内芯分别由一根金属导线组成,或由数根金属导线绞合组成;所述的数个金属内芯外依次包覆有导电层、绝缘层、屏蔽层和外护套。
能减少油管的堵蜡及频繁的刮蜡,能稳定产量;提温降粘减小井筒的流动阻力,增加泵效,减轻了抽油机负荷,延长柱泵周期
本实用新型的优点是:
本实用新型具有经济性,也便于控制,且不会污染原油。
附图说明
图1为本实用新型的结构剖视图。
具体实施方式
参见图1,一种自控温油井电伴热带,包括有数个金属内芯1,每个金属内芯1分别由一根金属导线组成,或由数根金属导线绞合组成;所述的数个金属内芯1外依次包覆有导电层2、绝缘层3、屏蔽层4外护套5。
