CHROMATOGRAPHIC ANALYSIS OF BENZENE HOMOLOG IN FORMATIO WATER AND ITS SIGNIFICANCE IN PETROLEUM GEOLOGY

The chromatographic analysis of benzene homolog in formation water is described. The detection limit of this method is 0.01ul/1. The recovery is around 90%, and the relative error is less than 6%. The compositional character of the benzene homolog and its geochemical significance have also been studied. According to the regularity of the variations in composition, toluene/benzene is considered to be an effective parameter in petroleum geology and geochemical exploration.
