常规裸眼压裂工艺是目前应用最广泛、成熟度最高的一套工艺管柱。其主要管柱组成如下： 顶部悬挂封隔器+裸眼封隔器+投球滑套+压差滑套+ 隔离阀+浮鞋+回接锚定密封总成。

● 顶部悬挂封隔器强度大，耐压高，可做为压裂后生产封隔器 

● 裸眼封隔器液压压缩式、水力扩张式、遇液膨胀式多种选择 

● 滑套特殊工艺处理耐冲蚀，适合于大排量作业

CONVENTIONAL OPEN HOLE FRACTURING TOOLS

The conventional open hole fracturing tools are the most widely used and mature technical string. Main Fracturing String Structure: Top  Suspension Packer + Open Hole Packer + Ball Actuated Frac Sleeve + Pressure Actuated Frac Sleeve + Wellbore Isolation Valve + Float  Valve +Tie-back Anchor Seal Assembly

◎ The Top Suspension Packer with high strength and pressure rating can be used as production packer after fracturing;

◎ Multiple choices of the open hole packer , hydraulic compression type, hydraulic expansion type, fluid expansion type;

◎ Sliding sleeves processed with special technics for high erosion resistance , suitable for large fluid volume operations.
