The composition of organic matter of Domanic deposit of the Bavly field

摘要

Core material taken from Zavolzhsky and Dankovo-Lebedyan horizons of the Bavly oil field attributed to the Domanic deposit is studied by thermal analysis methods. The content of total organic matter, the share of bitumoid and kerogen in it and their fractional composition are estimated. The features of fractional and hydrocarbon compositions of the bitumoids are revealed by thermal analysis, gas chromatography and IR spectroscopy methods. It is shown that, in some cases, the domanic deposit contains light hydrocarbons that can be extracted from the rock using solvents. An estimation of the oil-generating potential of the organic matter of the Zavolzhsky and Dankovo-Lebedyansky horizons is made.
