中文摘要 | 根據油氣產狀與特性分析、凝結油碳氫化合物分析及對比結果顯示,鐵砧山氣田 打鹿砂岩鐵通一層凝結油主要源自沉積介於濱海與接近開放性海洋之間環境,為海相有機物 輸入佔優勢之海相與陸相有機物混合之生油源岩。其儲油氣砂岩層部份疑不連通,凝結油碳 氫化合物生物指標成份分佈指紋亦有所差異, 生油源岩不盡相同。 其凝結油主要源自 0.7 ∼ 0.8 % Ro 生油源岩,部份源自較低成熟度 (近成熟∼ 0.7 % Ro) 之生油源岩。 鐵砧 山三十九號井木山層鐵通九層原油則源自約 0.85 % Ro 成熟度陸相有機物為主之生油源岩 。由採樣進行之油岩碳氫化合物分析對比發現所採鐵通構造下面之出磺坑層、碧靈頁岩及木 山層上部頁岩非其鐵通一層凝結油之生油源岩。 而北寮砂岩、木山層底部 (TT- 9th) 及五 指山層 (TT-10th) 之生油岩有機相則與鐵通一層部份凝結油類似。 綜合油 -- 油、 油 -- 岩對比及生油岩油氣生成潛能評估結果推論之, 鐵通一層凝結油主要源自於鐵通構造東側 -- 東南側之生油源岩,而鐵通構造打鹿砂岩層、北寮砂岩層中頁岩則提供部份油氣。 不過 此推論仍待進一步對其臨近地區生油岩進行研究探討。 |
英文摘要 | The results of the hydrocarbon characteristic analysis and the oil-oil correlation indicate that the condensates in the Talu Formation (TT-1) are mainly derived from the mixture of terrigenous organic matter and marine organic matter. As for the maturity assessment of oil samples, the values of biomarker maturity parameter indicate that those oils are of early to middle maturity level. At least three different biomarker fingerprints suggest that the oils might have come from different source rocks and the reservoir might have not been in succession. For the oil-rock correlation, the biomarker fingerprint of some rock extracts in the Peiliao Formation, the lower part of Mushan Formation (TT-9th) and the Wuchishan Formation are similar to that of some early maturity level oils in Talu Formation. According to the oil-oil correlation, the oil-rock correlation and the source rock potential evaluation, the discovered hydrocarbons of the Tiechenshan gas field might have been supplied mainly from the eastern deposition center and the remaining hydrocarbon from the Talu Formation and the Peiliao Formation of the Tiechenshan Anticline. |
