Description

The step-down extender that contains the lipopeptid biological enzyme
Technical field
The present invention relates to the oilfield water extraction technical field, the treatment agent of water is injected on particularly a kind of stratum, is a kind of step-down extender that contains the lipopeptid biological enzyme.
Background technology
At present, China has verified low permeability oil field geologic reserve 50 * 10 8T, most of oil fields rate of permeation is low by (0.3 * 10 -3～25 * 10 -3μ m 2).Porosity little (5～20%) injects water quality inferiority, and the sulphur salinity is high, and (1000～25000mg/L), the calcium ions and magnesium ions total amount is at 250～2000mg/L.After the exploitation of this type oil reservoir input, water injection pressure is high, and water pollution once again is further injured oil reservoir, and water injection pressure increases in time and increases progressively, and causes water injection pressure to reduce fast, can not normally accomplish injection allocation, even the oil recovery rate in oil field is reduced.How to solve the technical problem of low permeability oil field step-down augmented injection, improve the low-permeability oil deposit RF and become the current important topic of demanding urgently studying.
Summary of the invention
The objective of the invention is: a kind of step-down extender that contains the lipopeptid biological enzyme is provided, is used for the water injection in low-permeability oilfield well, reduce the WIW wellhead pressure, improve water injection rate.
