【摘要】：应用地质、地球化学、测井、地震反演、沉积相和构造埋深等资料,预测烃源岩厚度、有机质丰度和有机质类型等的平面分布,采用生烃潜力方法建立风城组烃源岩的生排烃模式,评价风城组致密油的资源潜力。结果表明:风城组烃源岩分布面积广、厚度大、有机质丰度高,有机质类型以Ⅱ型为主,目前处于低成熟—成熟演化阶段。风城组烃源岩在镜质体反射率Ro为0.5%和0.85%时分别达到生烃门限和排烃门限。风城组烃源岩现今累积生烃量为3.185×10~9 t,累积排烃量为1.531×10~9 t,残留烃量为1.654×10~9 t,其中云质岩致密油与页岩油资源量分别为0.613×10~9 t和1.565×10~9 t。综合分析认为,风城组烃源岩类型好、生排烃量大,为晚期排烃,具有广阔的致密油勘探前景。
[Abstract]:Using geological, geochemical, logging, seismic inversion, sedimentary facies and structural buried depth data, the plane distribution of source rock thickness, organic matter abundance and organic matter types are predicted.The hydrocarbon generation and expulsion model of source rock of Fengcheng formation was established by using the method of hydrocarbon generation potential, and the resource potential of dense oil in Fengcheng formation was evaluated.The results show that the source rocks of Fengcheng formation have wide distribution area, large thickness, high abundance of organic matter, and the type of organic matter is mainly type 鈪，
