Abstract

Abstract

Different Multifractal spectrum can be used for petroleum prospect evaluation. A typical multifractal model called the method of moments is employed to study the distribution patterns based on the multifractal spectrum forms obtained from 13 oil and gas indexes and 2 684 data in the deepwater area of central canyon of the Qiongdongnan basin. The results show that the indicators with strong multi-fractal characteristics in deepwater have wide and continuous fractal spectrum function features, forming a right side arc shape. While other indicators display weak or single fractal feature. Comparing the result with the one from factor analysis, shows that these results are generally consistent. In order to further examine the weights of these oil and gas indexes, principal component analysis was used to analyze these indicators. The results indicate that isobutane, normal butane, iso-pentane is important indicators to delineate hydrocarbon in the deepwater area.
