Abstract
The present invention makes three injection well profile control slugs of volume expansion granules profile control slug, polymer sol slug or basic group polymer weak gel slug and polymer strong gel slug be combined together, firstly uses volume expansion granules slug as front-stage slug, then uses polymer sol slug or basic group polymer weak gel slug as spacer fluid and propellant fluid, finally adopts polymer strong gel slug to make sealing operation so as to make the volume expansion granules be fixed on the target bed of high-capacity channel deep reservoir so as to raise the profile control success ratio.
Description
Technical field
The present invention relates to a kind of large channel oil reservoir deep profile controlling method of using composite slug method in the oil field development water plugging and profiling technology field.
Background technology
The depth profile control method that the macropore oil reservoir adopts at present mainly is the depth profile control method that adopts single volume expansion grain.Facts have proved,, make its deep can bring into play its obstruction property preferably at the macropore oil reservoir because volume expansion grain has deformability and the property cut apart again; But because under pressure, volume expansion grain continues migration, makes that when adopting single volume expansion grain to carry out deep profile controlling, individual well construction period of validity is short, and success rate is low.
Summary of the invention
The object of the present invention is to provide a kind of lasting migration that can effectively overcome single volume expansion grain, improve the success rate of macropore oil reservoir deep profile controlling and the large channel oil reservoir deep profile controlling method of using composite slug method of period of validity at earth formation deep.
The present invention is achieved in that three kinds of slugs are: first kind of slug (code name is K) is that volume expansion type granular and mineralized water are formulated, and working concentration is in the 0.1-10% scope; Second kind of slug (code name is J) is polymer sol or base polymer weak gel slug, the mineralized water preparation, and polymer sol is by mineralized water preparation polyacrylamide; The third slug (code name is N) is for the polymer strong rubber freezes slug, and this polymer strong rubber freezes by polymer and air aldehyde resin and forms.
Three kinds of slugs can be the K-J-N combination, also can be the K slug, and the J slug forms the multistage plug of alternate combinations, that is: K-J-K-J-N or K-J-K-J-K-J-N slug.This multistage plug alternate combinations can strengthen the viscous force of volume expansion grain in the stratum, slows down migration.
In three kinds of slugs, the K slug mainly is a volume expansion grain, also can singly use swell soil, kaolin.The J slug mainly is a polymer sol, also can adopt the polymer weak gel of base, and the N slug mainly is the strong gel slug of polymer, i.e. phenolic resin type or Lauxite type strong rubber or lignin gel.
The present invention makes up three kinds of water injection well profile control slugs (volume expansion grain profile control slug, polymer sol slug or base polymer weak gel slug, the strong gel slug of polymer); Performance volume expansion grain slug can carry out the advantage of macropore deep profile controlling, earlier with the volume expansion grain slug as the leading portion slug, then, use polymer sol slug or base polymer weak gel slug, adopt polymer strong rubber slug to seal at last as insulating liquid and PF.Also available three kinds of slugs are formed the multiple slug combination that replaces, and realize the efficient deep profile controlling of macropore oil reservoir.
The invention has the advantages that: adopt the large channel oil reservoir deep profile controlling method of using composite slug method, make the volume expansion type granular can be under the effect of the strong gel slug of polymer, be fixed on the target zone position in macropore deep, reach the purpose that improves success rate, facts have proved, adopt this method, the profile control success rate can bring up to 90% by 50%, and period of validity was brought up to 1 year or 2 years by three months.
