METHOD OF HYDRAULIC FRACTURING OF FORMATION Russian patent published in 2002 - IPC

FIELD: oil and gas producing industry, particularly, intensification of inflows of hydrocarbons and increase of their production. SUBSTANCE: method includes perforation of producing formation, filling of perforation interval with fracturing fluid with propping agent, running into well of powder pressure generator and its installation above upper holes of perforation interval, and its action on bottom-hole formation zone. Propping agent is used in the form of calibrated propping material of 0.3-0.5 mm fraction. Fracturing fluid is used in the form of composition containing used motor oils, synthetic fat acid, solution of NaOH alkali and mud powder in the following ratio, wt.%: used motor oils, 85.6; synthetic fat acid, 3.0; solution of NaOH alkali, 1.4; mud powder, 10.0. EFFECT: higher fluid permeability of bottom-hole formation zone after hydraulic fracturing in value and time. 1 tbl, 1 ex
