METHOD FOR CONSOLIDATION OF LIQUID STAGES IN FLUID SYSTEM FOR INJECTION INTO WELL |
摘要 |
FIELD: oil and gas industry.SUBSTANCE: invention relates to consolidation of liquid stages and can be applied to fluid system used for injection into a well. Method for consolidation maintenance of liquid stages in the fluid system used for injection into a well containing an interfacial fluid of another origin adjoining to the liquid stage lies in mixing of solid particles to at least liquid stage or to adjoining interfacial fluid in quantity when discrete borders of the interfacial fluid are formed between the stage and adjoining interfacial fluid and further injection of fluid system into the well bore. Method for consolidation maintenance of liquid stages in the fluid system used for injection into the well containing an interfacial fluid of another origin adjoining to the liquid stage lies in mixing of solid particles to at least liquid stage or to adjoining interfacial fluid in quantity when in streamline conditions discrete borders of the interfacial fluid are formed between the stage and adjoining interfacial fluid and at least a part of solid particles have adhesion properties promoting aggregation of solid particles at least inside the liquid stage or adjoining interfacial fluid and further injection of fluid system into the well bore.EFFECT: ensuring successful hydraulic fracturing.42 cl, 3 ex, 4 dwg |
