FIELD: oil-and-gas industry. SUBSTANCE: method includes running into interval of producing formation on flow string of strainer with telescopically extended branch pipes which extended before cementation with the aid of additional forcing-through plug with destructible diaphragm. The plug is forced by chemically destructible viscoelastic fluid, for instance, polyacrylalamide-chalk solution, and well is cemented using the common technology by means of cementing units. After cement settling, solution of hydrochloric acid destroys viscoelastic fluid in the hollows of filtering holes and communicate hollow of flow string with producing formation. Then, inflow of oil or gas is induced. EFFECT: higher quality of drilling-in and improved conditions for stimulating inflow of formation product. 1 cl, 1 dwg |
