PROCESS OF DIRECT GEOCHEMICAL SEARCH FOR HYDROCARBON POOLS Russian patent published in 2001 - IPC

FIELD: local prediction of hydrocarbon pools. SUBSTANCE: samples of under ground deposits are taken along profiles crossing tested area. True concentration C_tr of calcium is determined by quantitative method and tentative concentration C_tcn of calcium is found by way of spectral analysis by method of pouring and air blowing under condition that provides for independence of temperature of arc discharge from gross composition of samples. Losses for calcination are additionally determined in samples. Tentative concentration C_tcn of calcium is determined by calcium analytical lines of 300.68 nm and/or 272.16 nm. Factor of genetic information is computed per each sample which is C_tr/C_tcn, where C_tr is true concentration of calcium; C_tcn is tentative concentration of calcium. Judgment on presence of non-productive, productive, border ( geochemical barrier ) zones of hydrocarbon pool and zone of water-petroleum contact is made on package of values of losses for calcination and of factor of genetic information on lines of calcium in samples of under ground deposits. EFFECT: enhanced authenticity of process. 1 cl, 1 dwg
