METHOD FOR DETERMINING COMPOSITION AND PROPERTIES OF FORMATION FLUID BASED ON FORMATION GEOLOGIC CHARACTERISTICS Russian patent published in 2020 - IPC E21B49/08 G06F17/18 G01N33/26 

FIELD: chemistry.

SUBSTANCE: invention relates to reservoir geochemistry, and can be used for spatial binding samples of reservoir fluids to development objects (formations). Method of determining composition and properties of formation fluid, wherein method comprises determining list of composition parameters and / or properties of formation fluids, which provide distinguishability of fluids of analyzed formation pair, (by the same) based on value of at least one geological characteristic of pair of analyzed formations and based on established and fixed in database interrelation values of distance between formations in pair, and / or the steam permeability coefficient value, and / or values of density difference of formation fluids contained in formations of steam, with list of parameters of composition and properties of reservoir fluids of formation pair, which provide distinguishability of fluids relative to each other. Also disclosed is a computer system and a machine-readable medium for use in a method of determining composition and properties of a formation fluid.

EFFECT: simplification and reduction of time for determination of composition and / or properties of formation fluids with provision of reliable distinguishability of reservoir fluids relative to each other.
