对南黄海 1 2 4°E以西部分海域和陆区的重力数据资料进行了处理 ,并分析研究了该区的重力场特征 ,提出一个重力场滤波波长与相应的解释深度的经验关系式 .参考有关地质、地震等资料探讨了南黄海西部的深部构造格局 ,着重分析南黄海西部的北部坳陷的构造特征 ,以及讨论了该地区可能的油气有利前景 . The gravitational data data of some waters and land areas to the west of 114? E in the southern Yellow Sea have been processed, and the gravity field characteristics of the area have been analyzed, and an empirical relationship between the gravitational field filter wavelength and the corresponding interpretation depth has been proposed. The geology and seismic data discussed the deep tectonic framework in the western part of the southern Yellow Sea, focusing on the tectonic features of the northern depression in the western part of the southern Yellow Sea and discussing the possible favorable prospects for oil and gas in the area.
