松辽盆地梨树断陷油气资源动态评价

根据松辽盆地东南隆起区梨树断陷的最新勘探进展,结合地震、钻井、地化测试数据等资料,系统评价了梨树断陷烃源岩的有机地球化学特征,并分析了其展布特征及生烃潜力。利用盆地模拟法和油藏规模序列法,分别计算了区带资源量和预测了资源发现趋势,并对计算结果与三次资评进行了对比,分析了资源量变化的原因。

Dynamic evaluation of oil-and-gas resources of Lishu Fault Depression in Songliao Basin

Based on the latest exploration progress of the Lishu Fault Depression in the southeastern uplift of the Songliao Basin, combined with seismic, drilling and geochemical testing data, it was evaluated in this paper the organic geochemical features of hydrocarbon source rocks in the study area. The distribution characteristics and hydrocarbon generation potential of source rocks were also analyzed. By means of basin simulation and reservoir scale sequence methods, reserve amount was calculated and resource potential was predicted. The calculation results were compared with the previous evaluations, and the reasons for resource amount changes were discussed.
