CSS割缝筛管是在油套管上加工出缝隙的一种机械防砂器材。在缝隙宽度一定时，通过优化缝隙长度、缝隙密度和分布形式，在保留最低强度要求的条件下使过流面积最大化，进而确保割缝筛管拥有最优的过流能力。

◎ 管缝同体，便于下井；  

◎ 强度高，允许适当弯曲，适用于各种复杂井况；  

◎ 作为完井管柱起到防砂和支撑井壁的作用；  

◎ 施工简单，作业成本低；  

◎ 最小缝隙宽度：0.15mm；  

◎ 布缝形式分为A、B、C、D、E：

产品应用 

◎ 常规套管完井和裸眼完井； 

◎ 疏松砂岩中粗地层砂； 

◎ 对产量要求较低的油气井、水源井。

CSS SLOTTED SCREEN

INTRODUCTION

CSS slotted screen is a kind of mechanical sand control equipment that produces slots in oil casing. When the slot width is constant, by optimizing the slot length, slot density and distribution form, the flow area is maximized while retaining the minimum strength requirements, thereby  ensuring that the slotted screen has the best flow capacity.

FEATURES

◎ SPipe and slots in the same pipe body, which is convenient for downhole; 

◎ High strength, allowing proper bending, suitable for various complex well conditions; 

◎ As a completion string, it plays the role of sand control and well wall support; 

◎ Simple construction and low operation cost; 

◎ Opening minimum slot width: 0.15mm; 

◎ The distribution forms of slots are divided into A,B,C,D,E:

APPLICATIONS

◎ Conventional casing and open hole completions; 

◎ Loose sandstone and medium-coarse formation sand; 

◎ Oil and gas wells and water source wells with low production requirements.
