FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises well drilling, core recovery in drilling and core analysis for content of impurities. Note that spectral analysis is made to detect water-oil-insoluble salts of heavy metals and to fix their occurrence depth. Availability of said compounds allows making the conclusion on the location of super reservoirs in deposit. Quantitative content of said impurities in core rock allows making the conclusion on accurate location of interlayers. Said accurate location is used to take measures for prevention of well collapse by reducing the mechanical drilling rate.
EFFECT: simplified core analysis, higher validity, decreased accident rate.
