| Resumen | Transcripción del resumen del autor: Many BLTN14125eq1-rich (up to 97% by volume) natural gas pools have been found in the continental margin basins of the northern South China Sea. By combining the geochemical data from 53 samples with their geologic backgrounds, this study investigated the origins and accumulation mechanism of BLTN14125eq2, and discussed the role of BLTN14125eq3 in driving oil as it charged the reservoirs. The results reveal that the BLTN14125eq4 gases in the Yinggehai basin originate mainly from the thermal decomposition of both Miocene calcareous shales and Paleozoic carbonates, and that BLTN14125eq5 from mantle degassing is only a minor contributor. The BLTN14125eq6 accumulations in the Yinggehai basin are mainly controlled by diapiric faults and episodic thermal fluid movements. The BLTN14125eq7 gases in the eastern Qiongdongnan and western Pearl River Mouth basins are mainly related to magmatic or mantle degassing, and the volatiles from magmatic degassing during the igneous intrusion stage are the most likely major source of BLTN14125eq8 in these reservoirs, with basement faults providing pathways for upward migration of BLTN14125eq9-rich mantle fluids. Natural displacements of oil by BLTN14125eq10 appear to be common in the eastern Qiongdongnan and western Pearl River Mouth basins. The BLTN14125eq11-flooded oil or gas reservoirs have two common features that the present BLTN14125eq12 gas pools or oil-bearing structures have residual oils representing prior charge, and are close to the basement faults that provide pathways along which the mantle-derived BLTN14125eq13-rich gas was migrated. The oils from prior hydrocarbon reservoirs have been naturally driven out by BLTN14125eq14 to form secondary oil reservoirs in the eastern Qiongdongnan and western Pearl River Mouth basins. Therefore, a full understanding of the origin and distribution of BLTN14125eq15 cannot just be used to trace hydrocarbon migration pathways, but also provide useful information for risk assessment prior to drilling. |
