摘要
华北盆地天然气的主要类型是下第三系源岩在油气共生窗中生成的。平面上油气共存,纵向上气、油藏交错,气藏系列中缺少深层热裂解气。勘探该区时,只有查明气源条件、聚集条件和相态分异条件的良好配置区,才可能发现规模较大的气藏。
The natural gas of the main type in North China Basin is generated in the symbiotic window of oil and gas in Lower Tertiary source rocks. Laterally oil and gas coexists and vertically, the oil and gas reservoirs intersect each other. There is short of deep pyrolytic origin gas in gas reservoir serics. Only to find out the well matching region of the gas source, accumulation and phase state segregation condi- tions, a larger gas reservoir can be discovered while exploring this zone.
