基于深层油气藏的最新数据,对世界范围内深层碎屑岩油气藏富集规律及储层发育特征进行了统计分析.中南美和北美(不包括美国本土48州)深层碎屑岩发现的油气探明和控制(2P)可采储量最多,其中北美发现的石油2P可采储量最多,而中南美发现的天然气和凝析油2P可采储量最多.全球深层碎屑岩油气最富集的六大盆地依次为墨西哥湾、东委内瑞拉、阿拉伯、南里海、塔里木和圣克鲁斯-塔里哈盆地.在深层条件下,尽管储层通常表现为物性整体差,但仍可发育优质储层.深层油气勘探应立足于对“甜点”的预测,重点考虑颗粒薄膜、孔隙流体超压和盐岩发育对深层砂岩储层原生孔隙的保存作用.
Based on the latest data from deep reservoirs, the statistical analyzes on the enrichment laws and reservoir development characteristics of deep clastic reservoir in the world are made. The hydrocarbons discovered in the deep clastic rocks in Central and South America and North America (excluding 48 states in the United States) Probable and Controlled (2P) recoverable reserves are the largest, of which North America found 2P recoverable reserves of oil the most, while Central and South America found natural gas and condensate 2P recoverable reserves of the world’s deepest deep clastic hydrocarbon is the most abundant six The Great Basin followed by the Gulf of Mexico, the eastern Venezuela, the Arabian Gulf, the South Caspian Sea, the Tarim and the Santa Cruz-Tarim Basin. In deep conditions, high quality reservoirs can be developed despite the generally poor physical properties of the reservoir. Deep hydrocarbon exploration should be based on the prediction of “sweet spots”, with emphasis on the preservation of primary pores in deep sandstone reservoirs with granular films, pore fluid overpressure and salt rock development.
