Description
Technical field
The present invention relates to a kind of steady sand load fluid and preparation method thereof with suppression sand function, which is entering stratum
Have the function of inhibiting migration to reservoir sand afterwards.
Background technique
After currently used load fluid system enters stratum, the row of returning is led 10%~70%, and number of polymers enters stratum
Afterwards, big to stratum permeability injury, while can not all be discharged, the later period causes polymerization blocking serious.And siltstone and fine sand reservoir
Layer generally shakes out, and formation fines sand is migrated repeatedly around pit shaft, is easy blocking filling layer and nearly well high permeability zone, causes water conservancy diversion
Ability decline, influences oil well later period yield.Suppression sand agent has the function of steady sand suppression sand, plays to formation fines sand and inhibits migration
Effect, need enter stratum distal end (other than 3m), it is therefore desirable to suppression sand dosage it is larger, it is costly, and inject suppression sand agent after,
Later period operation be easy to cause suppression sand agent concentration to be diluted, and suppression sand effect cannot be effectively ensured.
Summary of the invention
For the above-mentioned prior art, the present invention provides a kind of steady sand load fluids with suppression sand function, fill carrying
After sand enters stratum, have the function of inhibiting migration to formation fines sand.
The present invention is achieved by the following technical solutions:
A kind of steady sand load fluid with suppression sand function, be made from the following raw materials in parts by weight: containing sulfonic group or/and
