Method of determining component composition of rocks khemogennykh deposits, including geophysical investigation of in a well for lithological log geological section, characterized in that is made geophysical investigation of acoustic, gamma-density, neutron and gamma-spectral methods along well bore in section khemogennykh deposits with discretization pitch along depth of 0.1 m and each point depth by algorithmic solution of system of equations at four measured geophysical parametres and known physical properties skeletal part rocks is determined quantitative content of prevailing 5 component of rock, including halite, anhydrite, sylvinite, calcite and glinyAK = dt1· v1 + dt2· v2 + dt3· v3 + dt4· v4 + dt5· v5; GGK -n = p1 · v1 + p2 · v2 + rare-earth · v3 + p4 · v4 + p5· v5; NGK = n1 · v1 + n2 · v2 + n3 · v3 + n4 · v4 + n5· v5; SGK = k1 ·Vl + k2 · v2 + k3 · v3 + k4 · v4 + k5· v5; v1 + V2 + v3 + v4 + v5 = 1 ; where : dt-time interval of run elastic waves, mcs/m, p-density, g/cm, n-indications of neutron logging, conventional units. u.), k-potassium content, %, v-volume (lobe U.) skeletal part rocks, respectively : 1-halite, 2- silvin , 3-anhydrite, 4-calcite and 5-clay.
