Abstract

Abstract:

The Kebai fault zone is one of most prolific areas in Junggar Basin.But its oil source is still poorly understood.Crude samples from the area feature in relatively low solidifying point and low content of saturation hydrocarbon and wax.The samples can be classified into type A and type B according to their biomarker characteristics.The distribution of different types of samples presents a clear zonation.According to the oil migration direction indicated by the geochemical index of crude samples,it is believed that the oil is mainly sourced from the source rocks in the overthrust Fengcheng Formation—a conclusion verified by the spatial distribution of strata in the zone.The pooling pattern in the area is also summarized and future exploration targets are predicted in the paper.

Key words: oil-source correlation, pooling pattern, Kebai fault zone, Junggar Basin
