Product features
This product is a new type of multi-scale self-degrading rigid temporary plugging agent for fracturing, which must be used in combination with polyacrylamide flexible temporary plugging agent. Combined with flexible temporary plugging agent, it can also alleviate the pressure relief block problem caused by the rapid dissolution of ordinary polyacrylamide temporary plugging agent. It is used to plug old fractures to open new ones and increase production volume. This product is environmental protection self-degradation material, in the formation temperature at the time of the solid particles soften into mud dissolved, no residue, viscosity close to water, easy backflow, little damage to the formation, is an ideal agent for fracturing temporary plugging.
