Dissolvable Temporary Plugging Ball
Dissolvable Temporary Plugging Ball
Conventional fracturing preferentially goes through high-permeability layers, while it is difficult to produce low-permeability layers that are extremely important for stimulation. In view of this situation, steering fracturing technology came into being. By adding a diverting agent to the fluid, these high-permeability channels are temporarily blocked, forcing the fluid to flow to the low-permeability layer, thereby realizing diverting fracturing.
Our company has developed a series of temporary plugging ball products for medium, high and low temperature use, which can adapt to different geological environments. It has good dissolution and degradation properties, and the degradation speed can be adjusted according to customer needs. At present, the main regular sizes are: 9mm, 12mm, 14mm, 15mm, 19mm, 22mm, 26mm in diameter. We can also be customized according to the actual needs of customers.
