Abstract:
The present invention relates to the field of profile control and flooding in oil fields, particularly to a colloidal nano-graphite-strengthened bulk gel system for dispersed particle gel, and composition thereof. The composition for bulk gel system, containing a polymeric matrix, a resin cross-linking agent, a coagulant, and colloidal nano-graphite, wherein, with respect to 100 parts by weight of the polymeric matrix, a content of the resin cross-linking agent is 30-150 parts by weight, a content of the coagulant is 5-100 parts by weight, and a content of the colloidal nano-graphite is 3-30 parts by weight; wherein, the polymeric matrix is partially hydrolyzed polyacrylamide with weight-average molecular weight within a range of 5,000,000-8,000,000 g/mol; the coagulant is one or more of chloride salt coagulant and alcohol amine coagulant. The specific components in the composition for dispersed particle gel in the present invention have excellent compatibility with each other, and can form a high-strength bulk gel system within 3-6 h at 85-95° C., and the obtained dispersed particle gel has relatively high temperature-resistance and salinity-resistance properties.

Claim (Index 2):
The composition according to  claim 1 , wherein with respect to 100 parts by weight of the polymeric matrix, the content of the resin cross-linking agent is 50-130 parts by weight, the content of the coagulant is 8-90 parts by weight, and the content of the colloidal nano-graphite is 4-20 parts by weight.
