根据阿斯特拉罕的地质——地球物理资料预测,在中泥盆纪下弗拉斯陆源碳酸盐和上泥盆纪杜内碳酸盐深层存在含油气圈闭。大量的石油和天然气聚集在上泥盆纪杜内碳酸盐深层中。阿斯特拉罕深层的两个模型预测了油气藏的聚集和储存条件。本文分析了古发育背斜的目前构造和特征,确定了勘探深层油气藏的有利位置,还预测了深层圈闭中的相态和烃组分。 According to Astrakhan’s geophysical and geophysical data, it is predicted that petroleum-gas traps exist in the deep Devonian carbonate and Upper Devonian-Dune carbonate during the Middle Devonian. Large amounts of oil and gas accumulate in the Upper Devonian Dunes carbonate bed. Astrakhan’s deep two models predict reservoir accumulation and storage conditions. This paper analyzes the current structure and characteristics of Paleozoic anticlines, confirms the favorable locations for exploration of deep reservoirs and also predicts the phase and hydrocarbon components in deep traps.
