| 摘 要： | 松辽盆地基底内部石炭—二叠系生烃潜力一直是人们关注的焦点。松深地震剖面和钻井资料显示:松辽盆地北部基底及其周边地区石炭—二叠系分布广、厚度大,主要分布于西部断陷区、中央断隆区和东南断隆区,林甸地区厚度达7 km;三肇地区及肇东地区厚度达到6 km,东北隆起区厚度达5 km。基底石炭—二叠系有机质类型一般为Ⅱ2—Ⅲ型,总有机碳含量高,热演化程度不均一。通过TTI-Ro法恢复了松辽盆地北部基底石炭—二叠系上覆地层沉积之前的热演化程度,有机质成熟度有明显变化,盆地东部有利于二次生烃。另外,松辽盆地石炭—二叠系具有二次生烃的热演化条件。石炭—二叠系油气远景主要受石炭—二叠系发育情况、二次埋藏前及二次埋藏过程中的热演化程度控制,松辽盆地北部石炭—二叠系存在3个有利的油气远景区:西部断陷区的林甸地区、东北隆起区的绥化断陷区、东南断陷区徐家围子断陷区。

| Abstract: | The potential of Carboniferous-Permian hydrocarbon has been the focus of attention within the basement of Songliao basin.According to Song-deep seismic profiles and drilling data,Carboniferous-Permian Formation of Songliao basin basement and its surrounding areas have wide distribution and large thickness,and mainly distributed in west depress area,the central fault uplift area and the southeast fault uplift area.Lindian has the most thickness of 7 km,secondly,in Three-zhao area,the thickness in Zhaodong is... |
