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.
