Abstract: In this paper, the regular of migration and accumulation model of oil or gas of Fengcheng and Mabei oilfield has been studied. On the basis studying, it is pointed out that the source rock is mainly the Fengcheng and Jiamuhe group of Mahu trough. The main transport passage of oil and gas is the fault and the permeability layer and unconformity surface. The period of migration and accumulation of oil and gas is Triassic system and from Jurassic system to Cretaceous system.There are two kinds of migration and accumulation model of oil or gas: first is side of sourceunconformityslopezone type, second is outside source unconformityfault controlsteps type in this region. On the basis studying the source rock and cap rock and trap, it is considered finally that the favorable object area of stratum reservoir is the PJ stratum of Wuerhe and Xiazijie and Mabei oil field.

Key words: the analysis of migration and accumulation model o, migration and accumulation model of oil or gas, source rock, reservoir, cap rock, trap
