ABSTRACT:
The invention relates to methods to stimulate formation production when oil recovering. Reducing cost and simplifying the manufacture of the propping material to prevent proppant carrying-over were achieved owing to the injection of the hydraulic fracturing liquid with a propping agent containing a propping material as randomly cut particles of the polymers reworked and being in irregular shapes with the maximum-to minimum size ratio more than 5. A propping material should be a material being resistant to hydraulic fracturing liquid, oil, gas condensate and oil-containing liquids, and salt water in the range of temperatures 40 to 140° C., plastic within pressure range of 7 atm to 700 atm, and having Young's modulus within 100 MPa to 20000 MPa. The propping material thickness can be within 10 to 500 micrometers. The propping material can be of flake-like, lamellar, and chip-like shapes or their mixture. The propping material content of the propping agent should be 0.1 to 30% by weight of the total propping agent mixture with the propping material. The propping material should be used for the hydraulic fracturing phase or at the end propping phase combined with portion of 10 to 50% of the total weight of the propping agent with the propping material.
