CS-HMR 液压坐封封隔器是单趟永久式可钻生产封隔器，在大斜度井、单 趟完井和注入井应用是理想的工具。

此封隔器具有一个整体式芯轴与密封孔，消除了可能的泄漏路径。它具有较 大的运动间隙，在大斜度井和水平井中有助于减少可能出现的问题的发生。金属 对金属密封的优质螺纹连接增加了封隔器的可靠性。

此封隔器坐封压力低，坐封后主要零部件被锁定防止退回，材料适合钻铣。  坐封过程中无需进行油管操作，液压坐封封隔器匹配有标准的附件。

上部密封筒(PBR) 可以通过锚定密封或Retch-Latch总成连接到封隔器上 部。上部密封筒(PBR) 也可以被取出回收。

CS-HMR PERMANENT PACKER

INTRODUCTION

CS-HMR hydraulic-set packer is a single-trip permanent mill able production packer. It is ideal for  highly deviated and/or single-trip production and injection applications.  This packer includes a one-piece mandrel and seal bore, which eliminates a potential leak path. It has  a low profile for greater running clearance to help reduce problems that may occur when running  in highly deviated and horizontal wells. Premium, metal-to-metal thread connections add to the  dependability of the packer. Ease of use has been proven in flanged-up, single-trip completions common in offshore operations.  This packer sets with low pressure, major components are rotationally locked, and materials are  suitable for milling. No tubing manipulation is required to set the packer, and the hydraulic-set CSHMR packer is compatible with standard accessory equipment. An upper polished bore receptacle (PBR) or overshot tubing seal divider can be connected to the  top of the packer with either a seal anchor or Retch-Latch assembly. The upper PBR assembly can be  retrieved with either connection. The internal seal assembly is run in place and shear-pinned to allow space out and fluid displacement.
