CS-RTTS 封隔器是一款全通径悬挂式封隔器，用于地层测试、酸化、挤水泥作业，大多数情况下，与 CS-RTTS 循环阀配套使用。CS-RTTS 封隔器主 要由J 形槽换位机构、机械卡瓦、封隔胶筒和液压锚定机构组成。当井下地层压 力大于封隔器上部压力时,封隔器液压锚爪伸 出卡在套管壁上，可防止封隔器下部 压力过大时推动封隔器上窜失封。其次还配有摩擦片和自动J 形槽套结构。 解封前，先打开循环阀使封隔器上下压力平衡，然后直接上提解封。

主要特性

◎ 全通径设计可以通过其大排量泵送流体，也可通过其它钢丝工具；

◎ 封隔器可以实现多次重复坐封； 

◎ 高强度锚爪提供更大的锚定力，可以锚定任何钢级的套管； 

◎ 压力通过油管激活液压锚定机构； 

◎ 可选循环阀，在挤水泥或注入期间可以方便地打开以循环液体。

CS-RTTS  MECHANICAL RETRIEVABLE PACKER

INTRODUCTION

The CS-RTTS packer is a full-opening hook-wall packer for testing, acid treating, and squeeze  cementing operations. Generally, the packer consists of a packer body and circulating valve. The  packer body includes a J-slot mechanism, a packing element, mechanical slips, and hydraulic anchor  mechanism. When the down-hole formation pressure is higher than the upper packer pressure, the  packer hydraulic anchor stretches out to the casing wall to avoid the upward flow communication and  packing failure due to too high lower packer pressure. Also equipped are friction plate and automatic  J-slot sleeves.  Before releasing, first open the circulating valve to equalize the upper and lower pressure of the  packer and then pull straight up to release.

FEATURES

◎ The full-opening design allows large pumping flow volume and passing of other wireline tools;

◎ Packer allows multiple re-set; 

◎ High-strength anchor provides greater anchor strength and can anchor casings of any steel grade; 

◎ The pressure triggers the hydraulic anchor mechanism by tubing;  

◎ Optional circulating valve, can conveniently open to circulate the fluids during squeeze cementing  or injection.
