产品说明

CS-HCA 封隔器是一款液压坐封、切割回收的生产封隔器。独特的设计使得封隔器 内径达到最大或穿越多条线缆。封隔器坐封时不会移动管柱，适合多级封隔器串联使用。

CS-HCA封隔器也可以配置为一个上提解封的封隔器。若预期有较高的压力，则它 可以设置为切割解封。在切割解封的设计中，封隔器芯轴被切断，封隔器与尾管一起回 收，不会在井内留下任何封隔器零件。

主要特性

◎ 内径较大，并带有多个线缆、管线穿越孔；

◎ 适用与单趟完井；

◎ 三节不同硬度的胶筒组成密封系统；

◎ 双向卡瓦设计，可同时承受上、下两个方向压力；

◎ 一体式桶式卡瓦，结构坚固可靠；

◎ 可选择切割解封或上提解封(特订)。

CS-HCA HYDRAULIC-SET RETRIEVABLE PACKER

INTRODUCTION

The CS-HCA packer is a hydraulic-set, cut-to-release production packer. The unique design allows either the packer ID to be maximized or to have multiple bores or control line feedthroughs. The large bore and no mandrel movement when setting make this packer ideally suited for multizone stacked packer applications.

The CS-HCA packer can be configured as either a straight-shear release retrievable packer, or, where high pressures are expected, it can be set up as cut to release. In the cut-to-release design, the packer mandrel is cut, and the packer with tailpipe is retrieved without leaving any packer components in the well.

FEATURES

◎ Large ID for maximum tubing size or multiple bores;

◎ Single-trip capability;

◎ Triple-seal multidurometer element package;

◎ Bi-directional, case-carburized external slips;

◎ Single-piece mandrel construction;

◎ Straight pull (in some cases) or cut to release.
