【摘要】：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.
[Abstract]:Based on the latest data from deep reservoirs, The enrichment law and reservoir development characteristics of deep clastic reservoirs in the world are statistically analyzed. The recoverable reserves of deep clastic rocks discovered in Central and South America and North America (excluding 48 states of the United States) are the highest. Among them, North America has the most recoverable oil reserves of 2P, while Central and South America has the largest recoverable reserves of natural gas and condensate oil. The six basins with the most oil and gas enrichment in deep clastic rocks in the world are the Gulf of Mexico, East Venezuela, Arabia, The South Rihai, Tarim and Santa Cruz Tariha basins. In deep conditions, although the reservoir is generally poor in physical properties, it can still develop high quality reservoirs. Deep oil and gas exploration should be based on the prediction of "desserts." The preservation of primary pores in deep sandstone reservoir is mainly concerned with granular film, pore fluid overpressure and salt rock development.
