压裂滑套，在封隔器之间采用滑套来形成压裂和生产通道。投球滑套通过投球后打 压剪切球座来开启。在压裂施工中可以在前一次压裂结束第二层压力开始时投入相应尺 寸的球来完成连续压裂施工。这种方式可以大大的减少压裂时间。并且很容易执行连续 多层压裂。

主要特性

◎ 特殊设计球座几何形状降低了球座的磨蚀； 

◎ 压力和温度等级可达10,000psi 与 350℉； 

◎ 出口流量面积是管内面积的两倍；

◎ 可以根据客户需要采用标准设计和耐酸腐蚀材质。

BALL ACTUATED FRAC SLEEVE

Ball Actuated Frac Sleeve performs fracturing and production port between packers by the sleeves.  Opening is done by applying pressure on the shear ball seat. Continuous fracturing operation can  be accomplished by injecting ball of corresponding size when the first fracturing is finished and the  second fracturing gets started. By this means, the fracturing time period can be much reduced and  it is easy to carry out continuous multiple fracturing.

FEATURES

◎ Special designed ball seat reduces the abrasion; 

◎ Pressure and Temp rating is up to 10,000psi at 350°F;

◎ Port flow area is double the tubing inner area; 

◎ Design standard and acid-resistant material can be customized.
