本研究的目標係針對台灣鐵鉆山及出磺坑地區地區油氣生產層中的裂隙儲積層，展開定性及定量的分析，以了解裂隙在隙儲積所扮演的角色特別是對生產的影響程度。研究的首要工作是確立裂隙在儲積層分佈的時空及其成因，由大而小區分不同的尺度等級以區分其不同的特性，以及利用現有的地下震測、電測及岩心資料來預測地底下裂隙定量的分佈，並比較裂隙特性與岩石物性之間的關係，以做為裂隙儲積層分類的依據；進一步整合各項地質、地物及物性資料對裂隙形成的地質環境綜合分析。最後由以上包含震測、電資料析及解釋、斷層處理、地質環境分析及整合解釋建立地質的模型，並將複雜的地質的模型與以簡化成裂隙的地質模型，以作為模擬油氣生產的參考指數。在第一年的計畫中我們完成有關技術性方面的分析，並實際應用在鐵鉆山礦區的岩心觀察及井測的資料。在第二年的研究除了鐵鉆山地區外，我們亦將出磺坑地區列為比較研究的礦區，因為該地區亦有較多及完整的井測、岩心及地下構造的資料。藉由研究兩個地區的成果建立一個整合裂隙油氣田地質資料評估的一個實例，並將此技術或研究模式推廣至目前正在開發的地區。 ; The main purpose of this research is to analyze the fractures, both qualitatively and quantitatively, and study the roles of fractures play in the fractured reservoirs in the Tiechanshan and Chuhuangkeng gas fields. The first approach is to identify temporal and spatial distribution, and occurrence of fractures in the reservoir rocks. Seismic profile, logging and core data are used to detect subsurface distribution, characterize the scale and zonation of fractures and their individual characteristics. Correlation between factures and rock physical data, such as porosity and permeability, can further be used to classify the reservoir type. In the next step, a generalized geological model can be established on the basis of integrating above geological, geophysical and rock physical data. The last step is to build up a simplified fracture parameter model from a complicated geological model on which a successful simulation of production in fractured reservoirs can be soundly based. In the first year research we have established analysis techniques of core and logging studies and applied to the Tiechanshan area. In the second we will focus on comparative studies on the Chuhaugkeng area, where sufficient drilled wells, 3-D seismic and geological data are available. Study results can be generalized as a case study and directly applied to practical oil and gas exploration and development. ; 研究期間 9801 ~ 9812
