中国近海沉积盆地按形成时代可以划分为新生代盆地和前新生代盆地． 新生代陆相碎屑岩断陷盆地有良好的油气前景， 而古生代还有广泛海相碳酸盐岩分布地区， 只要它们经受中生代挤压、改造后还能保留下来， 就具有巨大的油气潜力． 初步分析中国近海的油气勘探资料及大地构造演化史表明， 陆内断坳盆地下伏以古生代碳酸盐岩为主的残留盆地． 而陆缘盆地并不是寻找古生代残留盆地的场所． 但在台西南盆地、珠江口盆地潮汕坳陷发育海相中生代盆地． 前新生代残留盆地的地球物理研究方法是首先必须研究的， 主要包括残留盆地的综合地球物理处理新方法、确定残留盆地空间分布与空间结构的方法
China’s offshore sedimentary basins can be divided into Cenozoic basins and Pre-Cenozoic basins according to the age of their formation. The Cenozoic terrestrial clastic faulted basins have a good prospect of oil and gas, while the Paleozoic also has a wide range of marine carbonate distribution. As long as they are undergoing Mesozoic extrusion and can be preserved after transformation, they have great hydrocarbon potential . Preliminary analysis of oil and gas exploration data and tectonic evolution history of the offshore China shows that the continental basin is dominated by Paleozoic carbonates beneath the continental depression basin. The marginal basin is not the place to find the Paleozoic residual basins. However, in the basin of southwestern Taiwan, the marine Mesozoic basins are developed in the Chaoshan depression of the Pearl River Mouth Basin. Geophysical research methods of the Pre-Cenozoic residual basins are the first must be studied, including a comprehensive geophysical processing of residual basins, a method of determining the spatial distribution and spatial structure of the residual basins
