Abstract
The invention discloses an oil-water well sand consolidation agent and a preparation method and application thereof, belonging to the field of oil-water well sand consolidation. The sand consolidation agent for the oil-water well comprises the following components in percentage by weight: 41-45% of silicate aqueous solution, 8-20% of carbamide or ammonium carbonate, 0.06-0.1% of coupling agent and the balance of water. Wherein the mass fraction of the silicate in the silicate aqueous solution is 35-40%. After entering a petroleum reservoir, the oil-water well sand consolidation agent covers the surface of sand grains, silicate ions generated by hydrolysis of silicate and hydrogen ions generated by hydrolysis of carbamide or ammonium carbonate are combined at the temperature of an oil well of 60-100 ℃ to form polymer polysilicic acid, and silicon-oxygen bonds in the polysilicic acid are crosslinked into a three-dimensional network structure, so that a solidified layer is formed on the surface of sand scattering in the petroleum reservoir and is cemented together, and the sand output of the reservoir is controlled. Meanwhile, the sand consolidation agent for the oil-water well has small influence on larger cracks and pores in the stratum, thereby ensuring the permeability of a reservoir and the yield of an oil well.
