中文摘要 | 此研究專題發現鐵砧山氣田外海的近海地區具有造山運動前緣的構造三角帶。伴 隨著此構造三角帶的地質特徵有構造反轉斷層、隱伏逆衝斷層、火成岩的入侵以及流道雜系 , 形成複雜的構造演化系統,給予探勘專家及研究學者是一項艱困的挑戰。 雖然在潛能區 A1 打鹿砂層頂部的圈合面積約 3.15 平方公里, 油氣的蘊藏量評估約僅一千三百萬立方公 尺的天然氣。潛能區 A2,面積約 0.8 平方公里,具有油氣蘊藏量約三百三十萬立方公尺的 天然氣。依逆衝斷層發育的機制,打鹿砂岩下伏的木山層的斷層位移量應較淺部的打鹿砂岩 者為大,預估淨砂岩的厚度也會較打鹿砂岩 TT1A 層者為大。一般而言,就斷層的分析,淺 層者較短規模較小,深層者較長規模較大。因此,仍值得將木山層於此區的儲油氣特性再做 仔細的研究。 |
英文摘要 | It is found that there is a tectonic triangle zone in the study area, which is in the offshore area close to the Tiehchenshan gas field. The structural features that are characterized by inverted fault, blind thrust fault, volcanic intrusion and channel complex form a sophisticated tectonic evolution system and provide a good challenge to the experts and researchers. In the play A1, the closure area of the Talu Sandstoue top is estimated as 3.15 km �� and the amount of gas in place (GIP) is estimated as 1.3 × 10 �� m ��. In the play A2, the closure area of the Talu Sandstone top 0.8 km �� and the amount of GIP is 3.3 × 10 �� m ��. It is also deduced that based on thrusting mechanism the displacement of fault across the underlying Mushan formation should be larger than that across the Talu Sandstone. It is also predicted that the thickness of net pay sand in the Mushan formation would be thicker than that of TT1A member of the Talu Sandstone. Generally, the thrust faults with smaller magnitude and shorter length are in the shallower part while those with larger magnitude and longer length are in the deeper part. Therefore, it is Worthy to study the accumulation of hydrocarbon delineately and advancedly in this area. |
