| titleOfInvention | Hydrofracturing composition, method for preparation and application thereof |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to the treatment of a subterranean formation by hydraulic fracture thereof - hydrofracturing. Hydrofracturing composition containing a superabsorbent polymer, transformed into an expanded state and adapted to fracture in response to the occurrence of a fracture condition, a plurality of proppant particles disposed in a superabsorbent polymer prior to the release of a plurality of proppant particles from it in response to its destruction, a well treatment agent containing a sedimentation inhibitor, a tracer, a pH-buffering agent or a combination thereof, and a fluid for transforming the superabsorbent polymer to an expanded state, where the precipitation inhibitor contains a composition containing a carboxyl, sulfonic or phosphonic acid, a polymer containing a carboxyl, sulfonic or phosphonic group, or a combination thereof, the tracer contains fluorinated benzoic acid, a perfluorinated hydrocarbon, alcohol, ketone, organic acid, halogenated composition, or a combination of both, and the pH buffering agent is an alkali or alkaline earth carbonate salt, citrate, gluconate, phosphate or tartrate, alkaline earth metal oxide, organic polyelectrolyte, or a combination thereof. Method for placing a plurality of proppant particles in a fracture, comprising placing the above fracture composition in a bottomhole fracture, destruction of the superabsorbent polymer in the expanded state after placement in the fracture and releasing a plurality of proppant particles from a superabsorbent polymer to accommodate the plurality of proppant particles in the fracture. Invention is developed in dependent items of the formula. n EFFECT: technical result is to ensure high permeability and increase hydrocarbon production from formations subjected to hydraulic fracturing. n 12 cl, 17 dwg |
