Abstract
The invention provides a bioenzyme preparation which comprises the following components in percentage by weight: 25-45% of bioenzyme, 9-12% of polyethenoxy ether, 1-5% of sodium hydroxide, 10-15% of sodium silicate, 0.1-0.5% of alkyl glycoside, 1-12% of bis-quaternary ammonium salt and the balance of water. The bioenzyme preparation has the advantages of simple technique, favorable environment-friendly performance and no pollution, effectively enhances the water-injection capability and reduces the friction between the fluid and sandstone, thereby stabilizing the reservoir structure.
Description
Technical field
The present invention relates to biological technical field, be specifically related to a kind of biological enzyme additive.
Background technology
In commercial exploitation process, in the process of oil-field development, primary oil recovery is that crude oil relies on subsurface pressure at present, and by oil well, from the process that sprays ground, along with the reduction of beneath pressure, blowing finishes.By constantly, toward underground continuous water filling, supplement beneath energy, thereby realize the object of water displacing oil.But along with continuous water filling, moisture continuous rising in Produced Liquid.Therefore, generally carry out tertiary oil recovery in petroleum industry, i.e. the chemical displacement of reservoir oil, but existing oil-displacing agent, only pursue ultralow cross section tension force conventionally, do not focus on reservoir geologic character.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of technique simple, good environmental protection, it effectively improves water-injection capability, and reduce the friction of fluid and sandstone, thereby reach stable reservoir configuration, and good pollution-free to environment.
Biological enzyme formulation of the present invention, comprises that following weight percent counts:
Biological enzyme 25%-45%, Soxylat A 25-7 9%-12%, sodium hydroxide 1%-5%, water glass 10%-15%, alkyl glycoside 0.1%-0.5%, bi-quaternary ammonium salt 1%-12%, water surplus.
Described each components based on weight percentage is elected as: biological enzyme 30%, Soxylat A 25-7 10%, sodium hydroxide 3%, water glass 13%, alkyl glycoside 0.4%, bi-quaternary ammonium salt 8%, water surplus.
Utilize biological enzyme formulation provided by the invention, the wettability of oil bearing reservoir rock surface can be transformed from the wet direction of oil, thereby the wetting regime of change oil bearing reservoir rock reduces tension force, be that crude oil is easy to strip down from rock surface, also have certain viscosity reduction effect simultaneously.
Biological enzyme formulation of the present invention can also form one deck bioactive molecule film in surface attachment such as metal and rocks, stops precipitation of paraffin, play katalysis, change wax crystalline form state, stop the brilliant further growth of wax, the effect of anti-sealing injury, has effectively improved water-injection capability.
