中文摘要 | 本研究探討凝結油的成因與凝結油成熟度之判識方法,凝結油成因可歸納為兩大 類,即原生凝結油與次生凝結油;原生凝結油是由生油岩中之有機物直接受熱產生,可 分為(1)樹脂體受熱轉化而成(2)由於生油岩生成大量天然氣使原油溶解於天然氣中而形 成;次生凝結油是由原油轉化而成,可分為(1)原油受熱裂解而成(2)油氣受揮發分離作用 而形成(3)大量外來天然氣進入油層而形成。由凝結油之全油氣相色層分析與天然氣成份 分析結果發現臺灣地區之凝結油大部份受構造運動之影響,淺層油氣是由深層油氣經揮 發分離作用而成之次生凝結油,如錦水、青草湖和CBK地區之淺層;深層之凝結油則是 原油溶解於大量天然氣而形成之原生凝結油。凝結油成熟度之判織:已建立出磺坑地區 岩樣中芳香烴化合物之甲基�B比值、甲基菲比值及甲基菲指數與岩樣中有機物之%Ro關 係式,並應用於凝結油成熟度之判識。 |
英文摘要 | The origin of condensate can be devided into two categories:primary condensate and secondary condensate. The primary condensate can be formed either by thermal transformation from resinite at early mature stage; or by thermal cracking of gas-prone kerogen at mature stage. The secondary condensate is formed by thermal cracking of oil in the reservoir during deep burial, evaporative fractionation of oil during migration and intrusion of large amount of gas into the oil deposit. Various kinds of ratio among aromatic compounds, such as naphthalenes ratio (2MN/1MN) , phenanthrenes ratio (2MP/1MP) and methylphenanthrene index (MPI), were investigated to correlate the maturity level between rock samples and condensates from the CHK field, northwestern Taiwan. The empirical relationship established by Radke et al. has been proven useful for measuring the maturity level of condensates by calculating an equivalent vitrinite refrectance (Rc) value from MPI; % Rc= 0.6*MPI+0.4(when 2MP/1MP<1.97) and % Rc'=-0.6*MPI+2.3(when 2MP/1MP>2.56) |
