Abstract

The invention provides a basic profile modification agent used for petroleum exploitation, which comprises the following complex ingredients: a microbial polysaccharide curdlan and a hydrogen bonding power promoter or the microbial polysaccharide curdlan and a coagulant aid; the compound weight ratio of the microbial polysaccharide curdlan to the hydrogen bonding power promoter is 20: 1-1:1.5, the compound weight ratio of the microbial polysaccharide curdlan to the coagulant aid is 2:1-1:12, the hydrogen bonding power promoter, the coagulant aid are compounded with the curdlan for lifting the gel characteristics of the curdlan, the application range can be enlarged and the usage cost for the user can be reduced, the hydrogen bonding power promoter enables strong lifting of the gel strength of the curdlan under the high temperature state; the coagulant aid can reduce the gel initial temperature of the curdlan and can promote the effect of the hydrogen bonding power on the lifting of the gel strength; and the synergism of the coagulant aid and the hydrogen bonding power enables lifting of reinforcement effects.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a basic profile control agent for petroleum exploitation. Background technique [0002] Curdlan gum (Curdlan) is a new type of microbial exopolysaccharide produced by some variants of Alcaligenes sp., and it is also known as gel because of its unique property of forming gel under heating conditions. Make a hot gel. The chemical structure analysis of curdlan gum shows that it is an unbranched homogeneous polysaccharide polymer connected by a single D-glucose at the C1 and C3 positions with a β-1,3-glycosidic bond, belonging to the β-1,3- A special kind of glucan family. Molecular structure of curdlan gum: [0003] [0004] Curdlan gum has the characteristics of being able to form high-strength irreversible gels at high temperatures (above 80°C), so it is widely used in the food industry. It can significantly improve product quality, improve product water holdi...
