本发明涉及深海油田用潜油泵用电缆，特别是一种管缆以及管缆的制作方法及其应用。
背景技术
潜油泵电力电缆是潜油电泵机组配套使用的专用电缆，敷设于油井中，电缆下端与潜油泵及相关控制管线相连，上端与地面控制台相连接。电缆在油井中工作条件恶劣，常处于高温、高压，以及含油气等腐蚀性很强的环境中。由于电缆是非对称结构，当电力传输时，因磁场的不平衡而产生的电磁感应会引起磁滞损耗，使电缆发热，会严重影响电缆的使用寿命，需要勤换电缆，不仅影响工作效率、加大费用，而且会造成重大事故。
发明内容
本发明的目的在于提供一种能够提高电缆整体防腐蚀性和强度的管缆以及管缆的制作方法。
本发明采用如下技术方案：
一种管缆，包括电缆，钢管，所述电缆由导体结构以及套装在导体结构外部的绝缘结构构成，所述绝缘结构外部套装有钢管。
上述带有钢管层的结构，能够延长电缆的使用寿命，提高工作效率。
管缆的优选方案是：
所述钢管与绝缘结构等长设置。钢管长度大于3000米。
管缆的制作方法所采用的技术方案是：
一种管缆的制作方法，按如下步骤进行：
A、制造好的电缆置于钢带上；
B、将放置有电缆的钢带置放在制管机上，压制成成型管状；
C、前述成型管状结构的合缝处进行焊接；
D、利用探伤仪对焊缝进行检查；
E、对钢管外部进行抛光精整，即为管缆成品。
前述管缆的制作方法，能够实现大长度管缆的连续高速焊接生产，生产效率高。
管缆制作方法的优选方案是：
步骤A中的电缆按照国标的标准进行制作，根据相关规格的电缆选择适合尺寸的钢带，选择适合电缆及钢带规格的金属导辊、下压导轮。
步骤C中选择激光焊接装置对合缝处进行焊接。
利用涡流探伤仪对焊接完成的钢管进行焊缝检查。
在制作所述管缆的过程中，电缆放送装置、制管机、激光焊接装置及精整工序依次并列设置成流水生产线。
管缆的应用方法所采用的技术方案是：
在使用过程中对油田井下潜油泵直接提供动力修井时管缆直接输入或起出。
