METHOD OF DETERMINING EFFICIENCY OF FORMATION HYDRAULIC FRACTURING OF WELL Russian patent published in 2016 - IPC E21B43/267 E21B47/12 G01V5/10 

FIELD: oil industry.

SUBSTANCE: invention relates to development of oil deposits and can be used for geotechnical activities to increase oil production. Method consists in fact that before FHF preliminary complex geophysical survey of well (GSW) is performed and fluid of different mineral content alternately is pumped into perforation intervals with execution of GSW after each pumping. Then FHF is made with proppant and fluid with different mineral content is pumped again with execution of GSW after each pumping. Then comparative analysis of GSW before and after FHF is made, based on readings of pulsed neutron logging. Geophysical survey of well include gamma-ray logging, thermometry method, location of couplings and pulsed neutron logging.

EFFECT: technical result consists in determination of parameters of permeable areas of perforated intervals of well before and after formation hydraulic fracturing, analysis results of which show well productivity.
