New Techniques for Studying Production Contribution of Individual Horizon to Commingled oils

摘要

In this paper, three geochemistry analysis techniques used for study of production contribution of individual horizon to commingled oils were introduced, such as gas chromatography fingerprinting, inverse liquid chromato-graphy and partial least square ultraviolet spectrometry. The fundamental methods and technical steps of these three techniques respectively were illustrated with three different case studies. In the meanwhile the influence factors, application conditions and characteristics of them was discussed.
