珠一拗陷富烃洼陷古近系烃源岩生烃模拟实验及生烃贡献
Simulation Experiment and Hydrocarbon Generation Contribution of Paleogene Source Rocks in the Rich Hydrocarbon Depression of Zhu I Depression
摘要
Abstract
The Pearl River Mouth Basin,located in the eastern part of the northern continental margin of the South China Sea,is an important oil and gas bearing basin in China.Among them,many oil and gas fields and oil bearing structures have been found in the Zhu I Depression.The results of the second national resource assessment show that the oil and gas resources in the Zhu I Depression are dominated by oil,supplemented by natural gas,and have great resource potential.In order to systematically evaluate the hydrocarbon generation capacity of source rocks in the hydrocarbon rich sag of Zhu I Depression in the Pearl River Mouth Basin,two sets of four types of source rocks,namely,Wenchang Formation semi deep lake facies,shallow lake semi deep lake facies,Enping Formation shallow lake limnetic facies,and coal measures,were selected to conduct hydrocarbon generation simulation experiments in a semi open and semi closed system to comprehensively obtain the hydrocarbon generation dynamic model of source rocks.Under the guidance of the"genetic method"oil and gas resource evaluation method,combined with the basin simulation software,multiphase source rocks were used for the first time to fully confirm the Zhu I Depression from the thermal evolution degree of the hydrocarbon rich sag,the hydrocarbon generation history of the source rocks,and the intensity of hydrocarbon generation and expulsion.The hydrocarbon rich sag has a large amount of oil and gas resources,and these achievements provide a strong scientific basis for the further exploration and development of Zhu I Depression.关键词
