隨著全球對減碳需求日益增加，碳捕捉與封存（Carbon Capture and Storage, CCS）技術成為實現淨零排放的重要手段之一。透過CCS技術可將工業排放的二氧化碳捕捉、壓縮並注入深層地層中進行永久封存，有效降低二氧化碳排放、減緩溫室效應。台灣雖已初步辨識出幾個潛在的封存系統，但因地質構造破碎、地震活動頻繁，封存場址的可行性、安全性與長期穩定性仍需進一步評估，以確保其在永續發展上的有效性與風險管理。本研究運用淺層反射震測技術，針對桃園北部沿海地區進行震測調查，規劃六條測線分析此區域的地下地層構造，評估其作為二氧化碳封存場址之潛力。淺層反射震測相較於傳統探油震測具有較高解析度，能有效描繪地下數百米至三公里以內的地層變化，適合作為封存場址初步篩選所使用的地球物理方法。此外，為提升地層解釋的準確性，本研究運用兩種不同震測資料處理系統：Shallow Seismic System及RadExPro Professional，在資料處理上選擇對於每個步驟較為適合的軟體進行互補分析，強化訊號品質與剖面之清晰度。經過觀察最終剖面後，可發現該區域地層近乎水平且沒有明顯之地層錯動，而目標儲集層之厚度約為900公尺，顯示該地區具有良好封存潛力。本研究之成果不僅有助於瞭解桃園沿海地下地質構造，也為未來台灣將實施的二氧化碳地質封存計畫提供實質參考。;As global decarbonization efforts intensify, Carbon Capture and Storage (CCS) technology has become one of the key approaches to achieving net-zero emissions. CCS involves capturing carbon dioxide (CO₂) emitted from industrial processes, compressing it, and injecting it into deep geological formations for long-term storage. While Taiwan has preliminarily identified several potential CO₂ storage systems, the region′s fractured geological structures and high seismic activity demand comprehensive evaluation of site feasibility, safety, and long-term stability. This study applies the Shallow Seismic Reflection Method to investigate subsurface structures in the northern coastal area of Taoyuan. Six survey lines were designed to analyze geological features and evaluate the area′s potential as a CO₂ storage site. Compared to conventional deep seismic exploration, shallow seismic reflection offers higher resolution and is suitable for mapping geological formations within a few hundred meters to two kilometers in depth—making it ideal for early-stage site screening. Additionally, the study utilizes two different seismic data processing systems—Shallow Seismic System and RadExPro Professional—to optimize each processing step through complementary analysis. The final seismic profiles reveal nearly horizontal strata with no apparent faulting and indicate a target reservoir thickness of approximately 900 meters, demonstrating favorable conditions for geological CO₂ storage.
