中文摘要 | 綜合野外地質資料、大地電磁波資料分析、井下地質分析等,完成建構此研究區各地質剖面,為充分瞭解此區域性地質構造之滑離面,構造演化分析是重要方法之一。最後合理的完成竹湖斷層西北側番婆坑深部潛能區打鹿層頂部構造圖,找出認為深部番婆坑構造具有潛力的構造高區,因此,本研究特別注重背斜的細分,包括番婆坑深部背斜、竹湖深部背斜及竹東深部背斜,其打鹿頁岩頂部之圈合面積分別為0.47、2.53、1.45平方公里。完成番婆坑地區的50個MT測點,並完成三維MT測勘及資料解釋,油氣層的分佈往往伴隨著高電阻的出現,從高電阻區的觀點,在海平面下3400公尺~4000公尺的三維電阻分佈,顯示深部番婆坑背斜,深部下大湖背斜及深部竹東背斜均具有高電阻之異常,表示具有高的油氣潛能,其中以深部竹東背斜最具潛能。 |
英文摘要 | 3D Structures of three deep closures in the Fengpokeng area are developed by the integration of long geological sections, megnetotelluric data, and subsurface analysis. In order to understand the regional detachment in this area, the analysis of structural evolution is adopted. The closure area of Talu shale top of three closures, including Fengpokeng anticline, Tsuadahu anticline, and Chutong anticline, are 0.47, 2.53, 1.45 square kilometers, respectively. 3D MT (Megnetotelluric) survey was gathered from 50 stations distributed among Fengpokeng area. It is found that the hydrocarbon bearing zone is always showing the high resistivity. From the resistivity data of 3D MT, at 3400-4000 meters below sea level, the relatively high resistivity of Fengpokeng, Tsuadahu, Chutong anticlines implies that could have high hydrocarbon potential wherein Chutong has the highest one. |
