STABILITY, RELIABILITY AND HYDROCARBON ASSESSMENT OF PETROLEUM REMOTE SENSING ABNORMALITY IN SOUTH YELLOW SEA BASIN

摘要: 海洋油气遥感异常除了受油气地质条件控制外,还受到海流、潮汐、气象、海底地形、陆源物质、海洋生物等影响和干扰,为此,我们用相同处理模式,对南黄海不同时相MODIS数据进行了油气遥感异常的稳定性对比研究,并同周围已知海陆油气田作了对照比较。可以确定,海洋油气遥感技术的主要干扰为云层气候,其次是海流、潮汐,它可以有条件地有效揭示海域油气遥感异常。用经济实用型海上油气遥感技术处理解释的2002年3月7日的MODIS油气遥感异常是可信的,它正确反映了南黄海及其周围海域的油气田分布,可以作为海上油气勘探预测选区评价的依据。用相邻油气田的产能类比法估算,南黄海盆地是一个以勘探中、上古生界大-中型油气田为主,兼探白垩-第三系小油气田,可能发现2~3个中、上古生界大-中型油气田的油气勘探远景区。Abstract: Besides the geologic conditions, ocean petroleum remote sensing abnormality is also controlled by ocean current, tide, weather, sea-floor topography, terrestrial matter,and marine organism etc. So, we use the same processing mode to study the stability of South Yellow Sea petroleum remote sensing abnormality showed in different time phase MODIS data and compare it to that in the surrounding proved petroleum field. We are sure that the largest interference to the ocean petroleum remote sensing technique is cloudy climate, and then is ocean current and tide, as they can conditionally and availably reveal ocean petroleum remote sensing abnormality. So, the MODIS of petroleum remote sensing abnormality on 7 of March 2002 is believable,and it accurately reflect distribution of oil fields in South Yellow Sea and the adjacent sea area and can also be used as a basis to evaluate petroleum exploration targets. Through analogizing the neighboring oil field outputs, it is known that South Yellow Sea basin is an oil prospect region for large or medium-sized oil fields in the middle-upper Paleozoic and also for some small ones in the Cretaceous-Tertiary strata. Maybe two or three large or medium-sized oil fields can be discovered here.
