CS-ASIX 机械式生产封隔器是一种可取式、双向卡瓦、采用压缩或拉伸坐封的机械式 生产封隔器。 坐封后，它可以处于拉伸、压缩或中性状态，并且可以承受上下双向压差。大 的内部旁通在下入和取出时减小抽吸效应，并且在封隔器坐封后关闭。封隔器解封时，旁通 首先打开，在上卡瓦解卡前使封隔器上下压力平衡。CS-ASIX的另一个特点是上卡瓦解封 系统可以减小封隔器的解封力。无方向卡瓦首先解卡，可以使其它卡瓦解卡更容易。

主要特性

◎ 可以承受上下双向压差；

◎ 可以通过拉伸或压缩坐封； 

◎ 内置安全解封结构； 

◎ 旁通在上卡瓦下方，因此当旁通开启时，可以冲洗卡瓦上的碎屑，使解封更加顺利。

CS-ASIX  MECHANICAL RETRIEVABLE PACKER

INTRODUCTION

CS-ASIX Mechanical Production Packer is a retrievable, bi-directional slip compression- or tensionset production packer that can be left in tension, compression, or in a neutral position, and will hold  pressure from above or below. A large internal bypass reduces the swabbing effect during run-in  and retrieval, and closes when the packer is set. When the packer is released, the bypass opens first,  allowing the pressure to equalize before the upper slips are released. The CS-ASIX also features a  upper-slip releasing system that reduces the force required to release the packer. A non-directional  slip is released first, making it easier to release the other slips.

FEATURES

◎ Holds pressure differentials from above or below; 

◎ Can be set using tension or compression; 

◎ Only one-quarter right rotation is required to set and release; 

◎ A large internal bypass reduces the swabbing effect; 

◎ Optional safety-release features available upon request; 

◎ Elastomer options available for hostile environments; 

◎ Bypass valve is below upper slips so the debris is washed from slips when the valve is opened.

Note: Other specification products are available.
