【摘要】 彰武断陷构造位置位于松辽盆地南部,通过应用层序地层学的一般原理,利用钻井、地震等资料对彰武断陷进行了沉积储层的研究与预测。研究发现,彰武断陷整体为陆相碎屑沉积的砂泥岩互层,其中九佛堂组储层整体属于低孔、特低渗储层,且邻近优质烃源岩,地层厚度大,成藏潜力大。根据开发现状,目前需要对九佛堂组的有利储层进一步的预测。更多还原

【Abstract】 Zhangwu Fault Depression is located in the south of Songliao Basin.With general theories of sequence stratigraphy, study and prediction are carried out sedimentary reservoirs in Zhangwu Fault Depression,based on drilling and seismic data.It is found out that there exist alternating continental sedimentary sandstone and shale predominate.And Jiufotang reservoir is low-porosity and ultra-low-permeability in the vicinity of high-quality hydrocarbon source rock with thick formations and large potential of accumulation.According to the current development situations,further predictions are performed on favorable reservoirs in Jiufotang formation.更多还原
