| Abstract: | Chang 101 oil-bearing is a new exploration series in Ansai oilfield,Ordos Basin.The author emphasized sedimentation type and microfacies in Chang 101.Firstly,through the analysis the core observation,the author found there were dominance of symbols of shallow-water environment,such as leaves,root systems,worm hole and sedimentary structures in the cores.All the symbols indicated the relatively shallow water during its deposition process.Additional well-log information and test analysis information showed th... |
