采用加水的密闭产烃模拟实验技术,对中国近海主要含油气盆地第三系湖相、煤系和海相3类代表性烃源岩的石油生成过程、产出能力、成油规律及其产油率作了研究,在此基础上,结合石油地质条件,用成因法评价了各盆地的石油资源潜力,预测了石油资源分布,结果是:石油资源最富集者为渤海海域,其后依次为珠江口盆地、东海陆架盆地、北部湾盆地、琼东南盆地、莺歌海盆地.可见,湖相烃源岩发育的渤海、珠江口盆地、东海陆架盆地和北部湾盆地应该是中国近海海域石油勘探的首选领域.

The authors attempt to provide some suggestions to offshore China exploration based on the analysis of hydrous pyrolysis and subsequent genetic resources assessment.Hydrous-pyrolysis experiments were conducted in closed-system condition on the Tertiary lacustrine,coal measure strata and marine source rocks from six petroliferous basins to acquire information relating to hydrocarbon generation stages,potentials,kinetics and yield ratios.In conjunction with petroleum geological setting,resources potentials of each basin were evaluated by genetic method on the basis of hydro-pyrolysis results.The evaluation results show that the Bohai Bay Basin is the richest in petroleum resources,followed by Pearl River Mouth Basin,East China Sea Basin,Beibuwan Basin,Qiongdongnan Basin and Yinggehai Basin.Bohai Bay Basin,Pearl River Mouth Basin,East China Sea Basin and Beibuwan Basin with well-developed lacustrine source rocks are the promising petroleum exploration areas.
