The organosiloxane modified core-shell polyacrylate latex(ACR Latex) was prepared from acrylate monomer and A-174, by emulsion polymerization.The factors to affect the sandstone consolidation, including the mass fraction of ACR latex and crosslinking agent, consolidating temperature and time, and the sequence of the injection of latex and crosslinking agent, were studied.The orthogonal experiment result shows that the loss permeability of consolidation sand column can reach to the smallest if the mass fractions of latex and crosslinking agent maintain to 1.2% and 3% respectively, the consolidating temperature is kept at 65℃, consolidating time is 6 hours.
