摘要

本研究應用TemisPack二維盆地模擬軟體，將苗栗外海N礦區至P-1號井所圍區域內的四條震測剖面，模擬其各地層之成熟度、油氣生成、移棲等，評估此區域油氣潛能。除此之外，本研究更嘗試利用此四個剖面之模擬結果網格化（Griding），作成模擬結果之等值線圖及三維網格圖，如木山層成熟度等值線圖等，以延伸盆地模擬之應用，並加強瞭解苗栗外海E、N及P等礦區附近區域之石油系統探勘方法。從油氣生成移棲模擬結果，顯示有相當量的油氣移棲至E，W區域及P-1號井附近木山層及五指山層，值得往後探勘作進一步分析。本研究並以模擬結果描繪出本區域之石油系統事件圖表，期望盆地模擬對往後探勘有所助益。

This study applies the TemisPack and 2D basin modeling software to simulate the source rock maturation, hydrocarbon generation, migration and accumulation, etc. Four seimic cross sections, which surrounded as a '#＂ shape near W-1 to P-1 wells of Miaoli offshore area were analyzed. The separated simulation results were gathered and input into a 3D gridding software to build the contour and 3D wireframe maps for each stratigraphy such as maturity contour of Mushan Formation. These extended applications of 2D to 3D model may enhance the exploration of E, N and P area near Miaoli seashore. The simulation shows that there are considerable amount of hydrocarbon accumulations in the Mushan and Wuchishan Formation faulted belt among E, N and P area, especially in the Wuchishan Formation of western W-1 well and the high of Mushan Formation near P-1 well. The cross section and the critical moment petroleum system event chart of studied area are also drawn according to the modeling results.
