GEOCHEMICAL PROSPECTING FOR PETROLEUM

摘要: Examination of the rare publications on geochemical prospecting for oil shows that most workers have used only one method. It is believed by use a combination techniques can valid conclusions be drawn. A preliminary study showed there are means making numerous analyses under standard conditions in routine manner large number samples. In first stages laboratory work aim was to develop simple methods. Amongst these thin-layer microchromatography and gaseous phase pyro-chromatography. Using pyrograms rocks, disadvantages made dynamic regime Pye chromatograph were discussed relation flame-ionization static regime. Typical micro-chromatograms typical petroleum fractions presented. Qualitative interpretations particularly quantitative some rocks it possible demonstrate value pyrochromatography both surface subsurface oil. In second samples taken with an auger at depths about 2 m Company's concessions. The results obtained different analytical permit discussion validity this approach locating favourable zones accumulation depth.
