Abstract

本实用新型涉及一种中空保温套管。主要解决现有的套管为单层而无法起到保温作用的问题。其特征在于:所述铁管(1)内部设有外层不锈钢管(2),所述外层不锈钢管(2)内部设有内层不锈钢管(3),且外层不锈钢管(2)与内层不锈钢管(3)之间有间隙,且二者的端部焊接有挡板(4)。该中空保温套管内部中空,具有保温的作用,可以减轻油井结蜡。

Description

一种中空保温套管
技术领域
本实用新型涉及油田领域,具体的说是一种中空保温套管。
背景技术
套管是油田采油必备的设备,现有的套管通常为单层,直接与井壁接触,无法起到保温的作用,增加了油井结蜡出现的机率。
发明内容
为了克服现有的套管为单层而无法起到保温作用的不足,本实用新型提供一种中空保温套管,该中空保温套管内部中空,具有保温的作用,可以减轻油井结蜡。
本实用新型的技术方案是:一种中空保温套管,包括铁管,所述铁管内部设有外层不锈钢管,所述外层不锈钢管内部设有内层不锈钢管,且外层不锈钢管与内层不锈钢管之间有间隙,且二者的端部焊接有挡板。
本实用新型具有如下有益效果:由于采取上述方案,铁管内置有外层不锈钢管,外层不锈钢管内部置有内层不锈钢管,且二者之间有间隙,这样形成一个空腔,此空腔可以起到保温的作用,从而可以减轻油井结蜡。
附图说明
图1是本实用新型的原理图。
图中1-铁管,2-外层不锈钢管,3-内层不锈钢管,4-挡板。
具体实施方式
下面结合附图对本实用新型作进一步说明:
由图1所示,一种中空保温套管,包括铁管1,铁管1可采用与现有油井套管一致的材料制作,所述铁管1内部设有外层不锈钢管2,铁管1与外层不锈钢管2之间紧密接触,所述外层不锈钢管2内部设有内层不锈钢管3,且外层不锈钢管2与内层不锈钢管3之间有间隙,且二者的端部焊接有挡板4,使外层不锈钢管2与内层不锈钢管3之间形成空腔。上述的外层不锈钢管2与内层不锈钢管3均采用不锈钢3制作,使该套管内部形成空腔,可以减少热损失,起到保温的作用,减少油井结蜡。
