This technology from Huizhi holdings is based on the conventional fracturing fluid, adding weighting agent, increasing the density of fracturing fluid, thereby increasing the hydrostatic column pressure and reducing the construction pump pressure. At the same time, the delayed crosslinking technology is used to effectively reduce the construction friction. It is suitable for the fracturing of deep wells and deep wells with deep storage and high formation fracture pressure.
