    摘要： A scale inhibition method comprising: (a) injecting a dispersion of seed particles of an insoluble mineral salt in an aqueous medium into a formation through an injection well wherein the seed particles have an equivalent spherical diameter of 100% less than 100 nm, preferably 100% less than 50 nm, more preferably 100% less than 25 nm and the aqueous medium has dissolved therein precipitate precursor ions that form a precipitate of the insoluble mineral salt when contacted with resident ions in the formation; (b) allowing the dispersion to percolate through the subterranean formation towards production well and producing the dispersion from the production well; and (c) controllably precipitating the insoluble mineral salt onto the seed particles so as to reduce the deposition of the insoluble mineral salt onto the walls of the porous formation and/or onto the surface in the production well and/or onto the surface downstream of the production well.
