Abstract
A preparation method of a high-temperature cross-linking agent is applied to a cross-linking agent added during tertiary oil recovery in an oil field. Solves the problem that the cross-linking agent is not high temperature resistant when tertiary oil recovery is carried out. Is characterized in that: the high-temperature cross-linking agent comprises the following raw material components in percentage by weight: A. chromium acetate: 8-12%; B. phenol: 10-15%; C. urotropin: 5-8%; D. formaldehyde: 24-45%; E. m-diphenol: 0.05-1%; F. water: 20-40%. The effect is as follows: the high-temperature cross-linking agent has good stability and stronger gel effect at the temperature of below 120 ℃. When polymer flooding is carried out, the problem that the cross-linking agent is not high-temperature resistant is solved.
