SAND-CARRIER FLUID FOR HYDRAULIC FRACTURING OF FORMATION |
摘要 |
FIELD: oil-and-gas producing industry; may be used in change of filtering characteristics of formation and performance of hydraulic fracturing. SUBSTANCE: added to 311.5-371 ml (31.15-37.1 mas.%) of water is 30-40 g (3-4 mas. %) of clay; and added to next 311.5-371 ml (31.15-376.1 mas.%) of water is 8-12 g (0.8-1.2 mas.%) of carboxymethyl cellulose. Mixture is set stand for a day for swelling and mixed. Added to formed mixture is 20-25 ml (2.0-2.5 mas.%) of nonionic surfactant and 221-331 ml (20-30 mas.%) of used oil product based on petroleum oils (ρ = 0.905 g/cu.cm). Mixture is foamed. EFFECT: higher sand retentivity of fluid, i.e. stabilization in time of ability of produced system to retain sand of coarse fraction due to improved structural and mechanical properties of formed foam. 2 dwgc
