摘要:	二氧化碳地質封存技術可有效減少人為的二氧化碳排放至大氣中。台灣中部及濱海區有許多二氧化碳工業排放源。該區域有約8公里厚、由厚砂岩與厚頁岩組成之新生代沉積岩。本研究利用22口鑽井及84條陸海域反射震測剖面，研究二氧化碳封存系統之地質特徵，包含岩性空間分布、地層深度與厚度、儲集岩孔隙率與滲透率及封存量評估等。本研究也選定台中發電廠（TPP）、彰濱工業園區（CCIP）和麥寮台塑工業園區（MTIP）三場址，進行詳細場址特徵描述。封存系統由蓋層與儲集層所組成，由淺至深，包含：（1）R1系統：下部卓蘭層；（2）R2系統：錦水頁岩、桂竹林層、南莊層、觀音山砂岩，（3）R3系統：打鹿頁岩、北寮層、石底層，（4）R4系統：碧靈頁岩、木山層、五指山層。上述4系統展現空間深度變化及蓋層與儲層岩性橫向變化，導致三場址之適用封存系統不同。台中發電廠適合之封存系統為R1、R2及部分R3系統；彰濱工業園區適合之封存系統為R1、R2、R3與部分R4系統；麥寮台塑工業園區適合之封存系統為R3、R4及部分R1系統。封存量評估亦顯示研究區具優良之碳封存潛能，R2、R3、R4系統提供之封存量分別約為49.05億噸、56.23億噸及65.43億噸，共170.71億噸之封存量。本研究顯示台灣中部陸海域具備優良之碳封存潛力，能有效封存大量二氧化碳。研究成果為規劃碳封存商業運轉場址之關鍵參考依據。 ;Geological carbon storage is widely used to reduce carbon dioxide (CO2) emissions into the atmosphere. There are a few major stationary CO₂-emission sources in central Taiwan and it is ideal to find good carbon storage sites near the emission sources. The Cenozoic rocks in central Taiwan and its offshore area are up to 8 km in thickness and consist of several pairs of thick sandstone and shale layers. This study identifies carbon storage systems in the study area, including the spatial distribution of lithologies, formation thicknesses, depths, permeability, and porosity of the reservoirs, and storage capacity, using data from 22 boreholes and 84 onshore/offshore seismic profiles. This study selects three sites, the Taichung Power Plant (TPP), Changhua Coastal Industrial Park (CCIP), and Mailiao Taisu Industrial Park (MTIP), for site characterization. The storage systems in a descending order, each composes of a caprock and reservoir pair, are (1) R1 system of the lower Cholan Formation (Fm); (2) R2 system from the Chinshui Shale (Sh), Kueichulin Fm, to Nanchuang Fm, and Kuanyinshan Sandstone (Ss); (3) R3 system from the Talu Sh to Peiliao Fm and Shihti Fm; and (4) R4 system from the Piling Sh to Mushan Fm and Wuchishan Fm. The four systems above show spatial depth variations and lateral changes in the lithofacies of caprocks and reservoirs, leading to different storage systems from site to site. The TPP site is suitable for the R1, R2, and part of R3 systems; the CCIP site is suitable for the R1, R2, R3, and part of R4 systems; the MTIP site is suitable for the R3, R4, and part of R1 systems. Storage capacity results indicate significant storage potential. The storage capacity of R2, R3, and R4 is 4.905, 5.623, and 6.543 billion tons, respectively, totaling 17.071 billion tons. Our results indicate that central Taiwan and offshore areas have excellent CO2 storage potential and provide critical data for implementing commercial carbon storage sites.
