The Light Hydrocarbon Characteristics Of Gaoyou Sag Crude

GAO you, light dydrocarbon, Group division, crude

According to study Gaoyou Sag light hydrocarbon characteristics of crude oil and the oil is well divided. Characteristics of the light hydrocarbon ring parameters and carbon preference index in Mango revealed that depression source of crude oil and hydrocarbon source rocks are typical lacustrine depositional environment; C6-7 light hydrocarbon compositions of research and found that the C7 light hydrocarbon n-heptane, the relative content of methyl cyclohexane and methyl cyclopentane quite relative content of n-hexane in the the C6 light hydrocarbon composition of dominant. These characteristics indicate that the depression comes from rot muddy (I) organic matter; light hydrocarbon comparison star graph and maturity parameters in Gaoyou Sag, the group divided into A, B two groups, A group is low maturity crude oil Paleogene the Funing group (Elfl-4), B group is mature crude oil Paleogene Department of Dai Nam group (E2d1-2) and Cretaceous Taizhou the group (K2t1-2).
