为了预测南黄海盆地油气远景,利用最新采集的383个站位的低层大气烃类检测数据进行评价。烃类检测结果为:高值甲烷异常区主要分布在南黄海北部坳陷西南,次高值甲烷异常区主要分布在中部隆起带西部和南部坳陷中部,而南北向带状分布的甲烷异常带位于南黄海的东部。结合南黄海盆地航磁异常和部分浅地层剖面资料,认为中部隆起带东侧及紧邻的北部坳陷西南具有较好的油气远景。
In order to predict the oil and gas prospects of the southern Yellow Sea Basin, the latest 383 stations of low-level atmospheric hydrocarbon detection data were used for evaluation. The results of hydrocarbon detection are as follows: The high-value methane anomaly areas are mainly distributed in the south of the northern South Yellow Sea depression, the second-highest value methane anomaly areas are mainly distributed in the central part of the central uplift and the southern part of the southern depression, while the north- Located in the southern part of the South Yellow Sea. Combining with the aeromagnetic anomalies and some shallow stratigraphic data in the South Yellow Sea Basin, it is considered that there is a good prospect of oil and gas in the southwest of the northern part of the central uplift and the immediate north.
