       顶驱下套管装置是一种集机械、液压技术于一体,利用顶部驱动钻井装置进行下套管作业的一种石油装置。
 
      顶驱下套管装置上端与顶驱主轴相连接,可以通过顶驱精确控制下套管作业时套管的上扣扭矩、传递旋转及提升载荷,完成上扣及提放套管动作。该装置采用自封式皮碗密封套管,可以在下套管作业的同时循环钻井液,以减少或避免复杂事故的发生。
   

      主要技术特点

      1.通过顶驱上扣扭矩的准确控制,提高下套管的作业质量;

      2.通过液压驱动,可实现下套管自动化,降低劳动强度;

      3.与传统下套管作业相比,减少作业的综合成本;

      4.具有安全、高效的特点。
 
 
 
Casing running system
 
Casing running system is integrated with mechanical, hydraulic and electrical system; it is a kind of petroleum equipment, used Top Drive System to make casing running.
 
The upper end of Casing running system is connected with main shaft of TDS, which can accuracy control the make up torque of casing running, transmit rotary and lifting load, and finish make up and lift up and put down casing running movement. The casing running system can circulate drilling mud during casing running and reduce or avoid the accidents.
 
The main technical features
 
1.Increase casing running work efficiency by the accuracy control of make up torque.
 
2.Realize the automation of casing running and reduce labour intensity by the hydraulic drive.
 
3.Reduce the total cost compared with the traditional casing running system.
 
4.It has the features of Safety and high efficiency.
