DFS fracturing slide sleeve is a circulating slide sleeve that is mainly used for hydraulic fracturing operations in oil and gas wells. It is most widely used in the open eye segmented fracturing construction technology. The slide sleeve is opened by injecting fracturing balls of corresponding sizes into the tubing, thereby fracturing the target layer. The inner ball seat of the fracturing slide sleeve is made of drillable material, and oil production operations can be carried out after the ball seat is removed in the later stage.

Features/Advantages

Suitable for vertical or horizontal wells

The inner diameter size of the ball seat can be adjusted according to the fracturing stage

The ball seat is made of drillable material, which is convenient for later drilling and grinding

Normal working pressure 70MPa (10000Psi)

Normal working temperature resistance 177 ℃
