SELECTION OF PETROLEUM EXPLORATION AREA IN OFFSHORE CHINA——IN TERMS OF THE ANALYSIS OF THERMAL SIMULATION EXPERIMENTS AND GENETIC RESOURCES ASSESSMENT

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.
