摘要： Subterranean formations are treated with acid, by a method comprising the steps of: (1) forming an acidizing composition by mixing an aqueous acid component with at least one water-soluble organosilicon compound; and (2) injecting the composition into the formation. Suitable organosilicon compounds include water-soluble organosilanes and organosilanes which hydrolyze to form water-soluble silanols. By using the organosilicon compound, movement of formation fine particles is inhibited and swelling of clays by aqueous fluids is reduced, thus tending to maintain formation permeability.

摘要： A method for treating a fines-containing formation to prevent the migration and/or swelling of particulate matter. The method comprises injecting into the formation water and/or steam which contains at least one water-soluble organosilicon compound. Suitable compounds include those which are not normally considered to be water-soluble, but which hydrolyze to form water-soluble materials such as silanols.

摘要： A method for treating a subterranean formation, or a well penetrating the formation, comprises injecting into the well an aqueous composition containing an aminopolycarboxylic acid and a water-soluble organosilicon compound. By use of the method, scale is removed from well equipment and/or openings in the formation, and fine particles within the formation are stabilized to prevent their subsequent movement, resulting in increased, more stable fluid flow through the formation and well.

摘要： An aqueous composition comprises an aminopolycarboxylic acid and a water-soluble organosilicon compound. The composition is useful for removing scale from well equipment and/or openings in a subterreanean formation, and for stabilizing fine particles within the formation to prevent their subsequent movement. Fluid flow through formations and wells treated with the composition tends to be increased and more stable.
