英文摘要The North Yellow Sea Basin is one of the basins in offshore waters of China that have not undergone oil and gas exploration breakthrough. It is promising to use the hydrocarbon seepage phenomenon of sea-floor hydrocarbon reservoirs to predict hydrocarbon potentials in sea areas. In order to provide geophysical evidence for hydrocarbon prospect evaluation and further locating of target areas in the basin, we use the magnetic exploration method, one of the most economical and efficient geophysical methods of discriminating hydrocarbon seepage anomalies, and propose a supervised-learning-based pattern recognition method for recognizing magnetic anomalies related to sea-floor hydrocarbon-seepage alteration zones. Making full of both magnitude and textural features of magnetic anomalies, the method takes three kinds of basic elements (including point, polygonal line, and polygon) and their adjacent grid data cells as basic classes representing known constraint information like oil-encountering drill sites. The patterns or characteristic vectors extracted from the basic classes are used as templates to be matched or studied, and the similarity degrees between anomaly feature vectors and template vectors are calculated with the weighting Euclidean Distance function. In this way, the pattern matching is performed and the anomalies most similar to the templates are thus recognized. We apply the method to delineate alteration-induced aeromagnetic anomaly zones of the North Yellow Sea Basin. From the overlaying result of the anomalous zones with the distribution of Mesozoic strata and some geochemical anomalies (the detection results of anomalous hydrocarbon gases at the lower atmosphere and microbial germs in the subsurface sediments), the method is efficient in recognizing the magnetic anomalies related to alteration zones. The integrated analysis of regional structure, magnetic field, and geochemical anomalies of the study area shows that the seepage alteration-induced anomalous zones located in the eastern and northern part of the area may be promising hydrocarbon prospects in the North Yellow Sea Basin.
