Features /
1、After cementing, frac balls are released one by one to open each corresponding sliding sleeve and fracture the reservoir stage by stage.
2、The operation is fast, continuous and highly efficient. 3、Ball seats have good resistance to erosion. Easily drillable. Full bore can be achieved after drill-out. 4、Can hold high pressure and resist high temperature. 5、No need to use packers for interval isolation. 6、Can be repeatedly opened and closed with a shifting tool. Can be used in operations such as water shut-off, selective production and repeated fracturing. |
