METHOD OF THERMODYNAMIC STIMULATION OF BOTTOM-HOLE ZONE

摘要

mining. SUBSTANCE: method may be used for completion and production rate recovery of development wells whose production rate drops due to colmatage of formation. Claimed method includes heating of fluid in isolated interval of well by its pumping through hydraulic resistance unit. Fluid is pumped through circuit including subsurface oil pump outlet - hydraulic resistance unit - well interval isolated by packers. Fluid is heated due to dissipation of mechanical power. Heating results in pressure rise in isolated interval leading to decolmatage and formation of hydraulic fracturing. EFFECT: simple realization of method. 1 dwg
