产品应用 

◎ 对筛管外径尺寸有特殊要求的井； 

◎ 常规套管完井，尤其适用于裸眼完井，也可用于砾石充填防砂作业；

◎ 高温高压井、热采井、腐蚀性油气井和大修再完井。

ACS-2 BUTTON SCREEN

The button screen is directly processed with stepped holes on the base pipe. The reinforced filter  material is used to ensure the effectiveness of sand control while effectively reducing the outside  diameter of the screen. It is suitable for oil and gas wells that have restricted requirements on the  outside diameter of the screen.

◎ Small outer diameter, light weight, and low downhole friction;  

◎ Large effective flow area, high permeability, and high sand control accuracy;  

◎ Simple and convenient operation are conducive to reducing the operating costs and increasing  the success rate of downhole; 

◎ Strong deformation resistance; 

 ◎ Available 60 μm~300 μm filtration rating range products.

APPLICATIONS

◎ Wells with special requirements for the outer diameter size of screen; 

◎ Conventional casing completion, especially for open hole completion, can also be used for  gravel packing sand control operations;  

◎ High temperature and high pressure wells, thermal recovery wells, corrosive oil and gas wells  and the well completed again after the workover.

Note: The material, thread type, base pipe specification and filtration rating can be customized  according to customer requirements.
