Description
Technical field
The present invention relates to technical field of petroleum extraction, refer to a kind of oil production Basic profile modification agent especially.
Background technology
Curdlan (Curdlan) is a kind of novel Microbial exopolysaccharides produced by some mutation of Alkaligenes (Alcaligenes sp.), because it has the peculiar property forming gel in a heated condition, so also referred to as heat setting glue.The chemical structure analysis of curdlan show it be by single D-Glucose in C1 and C3 position with the branchiess homogeneous polysaccharide polymkeric substance that β-1,3-glycosidic link is formed by connecting, belong to one comparatively special in β-1,3-dextran family.The molecular structure of curdlan:
Curdlan has and (more than 80 DEG C) can form the characteristic of high strength irreversible gel under the high temperature conditions, thus food service industry is widely used in, it can significantly improve product quality, improve the retentiveness of product, visco-elasticity, stability, and have thickening power, make products taste better.In oil production, use amendment to be the important means improving recovery ratio and economic benefit, the action effect of amendment, action time, adaptability and cost are then several importances that profile control process will be considered.Curdlan injects and under stratum high-temperature, directly forms gel after oil well and its gellifying property is less by the impact of salinity, therefore can use good amendment as the different well depth oil recovery in oil field.With regard to the one-tenth colloidality of curdlan, there are two fatal defects, the starting temperature (80 DEG C) that one demand fulfillment is higher, under its two condition of high temperature, the gel-strength of gelinite is more much lower than the gel-strength under normal temperature, this single character in fixed temperature formation particular gel obviously can not meet the application demand of amendment well, picture is less than 3000m oil well, require just to form high-strength gel below 80 DEG C, be greater than 3000m oil well, the gel state of high strength still will be kept under requiring continuous high temperature state, pure curdlan cannot be accomplished, strengthening hydrogen bonding power material and coagulant aids material carry out composite by adding to have in curdlan, is the best mode solving this defect.
Summary of the invention
The present invention proposes a kind of oil production Basic profile modification agent, solves the curdlan problem that gel-strength starting temperature that is low compared with low-temperature condition and its formation high-strength gel is higher at high operating temperatures in prior art.The service requirements of high-temperature oil well and low temperature oil-well can be met by adjustment formula.
Technical scheme of the present invention is achieved in that a kind of oil production Basic profile modification agent, comprises following composite component: microbial polysaccharide curdlan and hydrogen bonding power promotor or microbial polysaccharide curdlan and coagulant aids; The composite weight ratio of described microbial polysaccharide curdlan and described hydrogen bonding power promotor is 20: 1 ~ 1: 1.5, and described microbial polysaccharide curdlan and the composite weight ratio of described coagulant aids are 2: 1 ~ 1: 12.
As preferred technical scheme, described hydrogen bonding power promotor is the one or several arbitrarily in Repone K, potassiumphosphate, calcium chloride, borax, and hydrogen bonding power promotor can promote the gel-strength of curdlan when the condition of high temperature strongly.
As preferred technical scheme, described coagulant aids is the one or several arbitrarily in ammonium nitrate, ammonium chloride, urea, Secondary ammonium phosphate, coagulant aids can reduce the gel initial temperature of curdlan and can strengthen the action effect that hydrogen bonding power promotor promotes for gel-strength, and when both act synergistically, the strengthening effect of its each side all gets a promotion.
Described oil production Basic profile modification agent be by microbial polysaccharide curdlan and hydrogen bonding power promotor and coagulant aids composite rear soluble in water, afterwards by gained solution gel 8 ~ 12min at 45 ~ 95 DEG C, obtained described oil production Basic profile modification agent, described microbial polysaccharide curdlan and the composite weight ratio of described hydrogen bonding power promotor are 20: 1 ~ 1: 1.5, and the composite weight ratio of described microbial polysaccharide curdlan and described coagulant aids is 2: 1 ~ 1: 12.
Owing to have employed technical scheme of the present invention, a kind of oil production Basic profile modification agent, comprises following composite component: microbial polysaccharide curdlan and hydrogen bonding power promotor or microbial polysaccharide curdlan and coagulant aids; The composite weight ratio of described microbial polysaccharide curdlan and described hydrogen bonding power promotor is 20: 1 ~ 1: 1.5, the composite weight ratio of described microbial polysaccharide curdlan and described coagulant aids is 2: 1 ~ 1: 12, by by hydrogen bonding power promotor, the composite gel property promoting curdlan in curdlan of coagulant aids, can expand its use range and reduce the use cost of user, hydrogen bonding power promotor can promote the gel-strength of curdlan when the condition of high temperature strongly; Coagulant aids can reduce the gel initial temperature of curdlan and can promote the action effect that hydrogen bonding power promotor promotes for gel-strength; During both synergies, the strengthening effect of its each side all gets a promotion.
