       頂驅下套管裝置是一種集機械、液壓技術于一體,利用頂部驅動鉆井裝置進行下套管作業的一種石油裝置。
 
      頂驅下套管裝置上端與頂驅主軸相連接,可以通過頂驅精確控制下套管作業時套管的上扣扭矩、傳遞旋轉及提升載荷,完成上扣及提放套管動作。該裝置采用自封式皮碗密封套管,可以在下套管作業的同時循環鉆井液,以減少或避免復雜事故的發生。
   

      主要技術特點

      1.通過頂驅上扣扭矩的準確控制,提高下套管的作業質量;

      2.通過液壓驅動,可實現下套管自動化,降低勞動強度;

      3.與傳統下套管作業相比,減少作業的綜合成本;

      4.具有安全、高效的特點。
 
 
 
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.
