摘要

A method for causing a screening in treatment of stimulation of subterru00e1neas formations, and a method of compaction of gravel in a training subterru00e1nea ".The methods are present to cause a screening during the fraturau00e7u00e3o of an underground formation and treatment of compaction of gravel that has a fluid carrier viscoelu00e1s surfactant.Tico entering the filter cake in at least a portion of which is a base material soluble by injecting sludge of agent of the backrest.And causing hydrolysis and dissolution of the solid material base soluble, which adds a base so that the leakage increases, the concentration of agent of the backrest in the fracture increases.And agent of the backrest has a sifting.A method of compaction of gravel with a fluid carrier base soluble, injecting gravel, and causing hydrolysis and dissolution are present.And the addition of bridging material - promotion is included.
