Reservoir Organic Geochemical Description-An Example from Carboniferous Reserviors on the Tazhong 4 Structure in the Tarim Basin

摘要

摘要: 运用棒色谱ＴＬＣ－ＦＩＤ和油显示仪ＯＳＡ对塔中四号构造ＴＺ４、ＴＺ４０２及ＴＺ４０１井石炭系岩芯进行密集采样分析（约３个/ｍ），并选择典型原油进行ＧＣ、ＧＣ/ＭＳ和碳同位素分析。研究表明，石炭系储层油族组成在横向和纵向上都存在明显的非均质性；纵向上可分为三段：CⅢ₁（油层段）；CⅢ₂CⅢ₃（油水同层段），CⅢ₂CⅢ₃中局部含油率较高的层段可能有试油价值。推测原始油藏可能受喜山阶段的构造运动破坏，CⅢ₃油气发生过自西向东的再分配，CⅢ₂油气则沿断层向上溢出，形成现今具两期古油水界面的油水系统格局。据横向上存在的成熟度差异，推测来自下古生界的主力油源注入方向可能是由北西向南东；但色谱和碳同位素等资料反映TZ401井所在的１号高点可能有另一次要的源自上古生界的原油混入。
