摘要:
北部湾盆地是中国近海重要的富油盆地之一,但其主要凹陷探明油气地质储量和油气性质存在显著差异。本文利用丰富的烃源岩和油气地球化学分析资料,从区域上分析了北部湾盆地主要凹陷烃源岩和油气的地球化学特征及其变化规律,首次对各凹陷油气差异性及其控制因素进行了较为全面、系统的研究。研究结果表明,从涠西南凹陷到乌石凹陷,再到迈陈和福山凹陷,探明油气地质储量减少,已发现油气的气油比增大、原油密度降低,原油中反映藻类生源的生物标志化合物含量降低,而反映高等植物生源的生物标志化合物含量增加。分析认为,流二段优质烃源岩发育程度是控制该盆地主要凹陷油气富集程度的重要因素,而烃源岩有机质类型和成熟度是控制该盆地主要凹陷油气性质的重要因素
Abstract:
The Beibuwan basin is one of the most important oil-rich basins in offshore China, but there are significant differences in the proved oil and gas reserves in place and the properties of oil and gas from its main sags. Based on the abundant source rocks and hydrocarbons geochemical analysis data, this paper regionally analyzed the geochemical characteristics and change laws of the main source rocks and hydrocarbons in the main sags of the Beibuwan basin. It also studied the differences and controlling factors of hydrocarbons in each sag comprehensively and systematically for the first time. The research results show that from the Weixinan sag to the Wushi sag, and then to the Maichen and Fushan sags, the proven oil and gas geological reserves tend to decline, the gas-oil ratio of discovered oil and gas increases, and the density of crude oil is decreased. The content of biomarker compounds in crude oil which indicates the algae origin is decreased, while the content of biomarker compounds reflecting higher plants origin increases. According to analysis, it is considered that the development degree of high-quality source rocks in the Liu 2 Member is an important factor controlling the oil and gas enrichment of main sags in this basin, while the organic matter type and maturity of source rocks are important factors controlling the oil and gas properties of main sags in this basin
