摘要
我国近海沉积盆地已发现的油气大部分产于陆相第三系。随着勘探工作尤其是地球物理勘探的逐步深入 ,在我国东海南部和南海北部陆坡深水海区 ,包括潮汕坳陷和台西南盆地的地震调查对可能存在的海相中生代地层的了解已取得了突破性进展。调查成果结合区域地质背景 ,认定海相中生代沉积主要来自由西而东的特提斯入侵。而寻找海相油气将会成为我国海域油气勘探的重大目标。
The already proved oil and gas in offshore China is mostly found in the continental Tertiary. With the going on of the exploration work especially geophysical prospecting, breakthroughs have been made in the understanding of the possible marine Mesozoic through seismic surveys in the deep water areas in the south of the East China Sea and in the north of the South China Sea (including Chaoshan depression and Taixinan basin). Together with the regional geologic background, the survey results indicate that the marine Mesozoic sediments mainly came from the invasion of the Tethys from west to east. Searching for marine petroleum will become an important object in the future explorations.
