  • Based on analyses of accumulation material basement,event and mode in the east of Manjiaer region of the Tarim Basin,it has been found out that,besides kerogen source rocks rich in carbonate from Cambrian to Middle—Lower Ordovician,there also exist regenerated hydrocarbon source rocks represented by ancient reservoirs.Formation of accumulations has experienced 3 stages:1) palaeohighs generation and accumulations formation in Middle Caledonian;2) palaeohighs uprising and erosion as well as accumulations destruction and adjustment from Late Caledonian to Indosinian;3) upper structural folds and traps formation as well as cracking gas infilling from Late Yanshanian to Himalayan.The 3rd stage is the main accumulation stage and mainly forms gas pools.
