Abstract

In This study Geochemical, Physical and Chemical analyses on sample of BITUMENs had been done for the purpose of Geochemical evaluation and BITUMEN Geology in Aligodarz area in Lorestan provine and the results of these analyses were compared with the Geochemical analyses which were done on BITUMENs of Chamsangar area. the Geochemical analyses include: Sediment separation of Asphaltene, fraction seperation and molecule analyses include: Gas Chromatograph, Gas Chromatograph-Mass Spectrometer. Physical and Chemical analyses include: XRD and XRF percentage of BITUMEN liguidation in different solvents, percentage of Ash rate, percentage of S, N, C, H, O rate. the result of Organic Geochemical tests show that most of the samples of Chamsangar area which are Garau Formation have the must percentage of Saturate Hydrocarbons and Aromatic and in comparision with the BITUMEN sample in Emamzade Davood area (in the proportion of 7.2-11%), the natural situation and the Organic materials condition show the Garau Formation sample. Intense decrease of Saturate fraction and Aromatic of BITUMEN sample show that this sample has undergone some oil Alteration (Biodegradation, Corrosion and Evaporation). During thousand years and Because of this reason the percentage of Asphaltene is unusually very high in the sample. The study of spectrums which are produced from Gas Chromatograph shows that most of the normal Alkanes of Saturate fraction had been disappeared from Chromotogram background. which represents the severe transformation of Organic materials in this sample.The existence of C16 to C20 seems unnatural in this Chromatogram. But it's in the case that heavy Alkanes (mostly C21) are not seen in the Chromatogram background in other words, while Hydrocarbons are moving from deeper Formation (probably Garau Formation), They clean the Organic materials in the younger Formations (like Gurpi Formation) and are unnaturally gathered. By tracing the Pri/n-C17 parameters EMAMZADEH DAVOOD BITUMEN sample and comparing the maturation condition, the sedimental environment of source rock shows that the kerogen of source rock is the type of P and III.
