Description

一种套管驱动装置
技术领域
本发明涉及一种钻井钻井装置,特别涉及一种连接套管和钻头的钻井装置。 
背景技术
目前油井的开采均是采用钻杆带动钻头来钻探,钻杆为刚性连接结构,在钻井的过程中容易造成钻杆的损伤,容易给生产带来较大的困难,目前有研究提出利套管代替钻杆进行钻井作业,可以一边钻进一边下套管,完钻后将套管直接固井,但是如何驱动套管的作业仍是一个难点。 
发明内容
本发明旨在提出一种利用套管驱动钻头作业的套管驱动装置。
本发明所述的一种管套驱动器,包括驱动本体,所述的驱动本体上部设有上接头,本体中部设有卡瓦,本体上还设有支撑环,所述的支撑环设置于本体下部,支撑环上包裹有密封皮套,本体下部设有下接头。
本发明所述的一种钻套驱动装置,将套管与钻头通过本装置连接起来,代替了钻杆的作用,减化了生产步骤,本发明结构简单,实用性强。
附图说明

具体实施方式
实施例1。
本发明所述的一种钻套驱动装置,包括驱动本体1,所述的驱动本体1上部设有上接头2,本体1中部设有与本体1活动连接的卡瓦3,本体1上还设有支撑环4,所述的支撑环4设置于本体1下部支撑环4上包裹有密封皮套,使用时将动力装置与上接头2相互连接,卡瓦3固定在管套内部,支撑环4和套管密封连接,下接头与钻头相互连接。
