摘要:

针对目前廊固凹陷油气成藏机制不够清晰,油气运移和输导体系仍不明确等问题,首先从反映油气运移和输导体系通道的参数筛选入手,重点分析含蜡量和油田水矿化度随埋深的变化规律,进而根据其垂向的分布组合样式,总结出A型(常规层析型)、B型(快速通道型)和C型(孔隙—裂缝型)3种油气藏输导体系类型,并按构造区带分析了不同输导体系约束的油气藏的空间展布特征。然后研究输导体系对油气藏的深度、规模、类型和相态的控制作用。最后根据输导体系类型划分方案建立了4种成藏模式,为油气勘探方向和勘探目标的预测提供重要依据。

Abstract:

Based on the problems that the reservoir formation mechanism of Langgu Depression is not clear and the hydrocarbon migration pathway system is indefinite currently, this paper filters parameters of affecting hydrocarbon migration and pathway, and emphasizes on the relationship between wax content, oil field water salinity and buried depth. Combining with its vertical assembling pattern, three petroleum migration pathway system types are summarized: A type(conventional chromatography),B type(express pathway),C type(porefracture), and the spatial distribution features of diverse reservoirs at various structural belts are studied. The control over the depth, scale and categories of reservoir and petroleum phase by pathway system types is researched. Finally, according to scheme of classification of migration pathway system, four models of hydrocarbon accumulation are established and petroleum accumulation unit is determined. It can provide significant information for the oil and gas reservoir simulation, exploration direction and exploration target prediction.

Key words: Langgu Depression, hydrocarbon migration parameter, migration pathway system type, petroleum accumulation model
