一种专用于高温热采井底部完井设计的可回收式封隔器，下入时可悬挂下部工具重量， 坐封完成后可丢手实现内、外管柱分离，充填时密封油管和套管环空。通过钻杆打 压推动坐封工具活塞，剪断坐封销钉，推动卡瓦，压缩胶筒。如需取出，可下入专用回取工具。

主要特性

◎ 整体式双向卡瓦，表面渗碳处理易于切入P110或更硬钢级套管，锚定可靠； 

◎ 下入、坐封、回收过程中无需旋转管柱； 

◎ 内锁紧机构不易脱扣，可靠性高； 

◎ 胶筒承压能力强； 

◎ 内通径大，易于后续施工作业；

◎ 能够传递较大扭矩，工具遇阻或下入困难时可旋转管柱。

HIGH TEMPERATURE TOP PACKER

INTRODUCTION

The utility model relates to a recyclable packer specially designed for completion at the bottom of a high  temperature thermal recovery well. The packer can suspend the lower tool weight when descending,  release the inner and outer tubing string separation after setting, and seal the tubing and casing annulus  when filling.Push the setting tool piston through the drill pipe, cut the setting pin, push the slip and  compress the rubber barrel.If you need to take it out, you can enter the special callback tool.

FEATURES

◎ Pintegral two-way slip, easy to cut into P110 or harder steel grade casing for surface carburizing,  reliable anchoring; 

◎ Pintegral two-way slip, easy to cut into P110 or harder steel grade casing for surface carburizing,  there is no need to rotate the string in the process of downloading, setting and recovery; 

◎ the internal locking mechanism is not easy to trip and has high reliability; 

◎ strong pressure bearing capacity of rubber cylinder; 

◎ large inner diameter, easy for follow-up construction; 

◎ it can transfer a large torque, and the pipe string can be rotated when the tool is blocked or  difficult to descend.
