摘要: 对风城油田和玛北油田进行成藏分析,认为烃源岩主要为玛湖凹陷的二叠系风城组,其次为佳木河组;输导层主要为断层、层内渗透层和不整合面;两个成藏期分别是三叠纪末和侏罗纪末—白垩纪;存在两种类型的成藏模式,一是三叠纪—源内—不整合—断控原生油气藏成藏模式;二是侏罗白垩纪—源上—不整合—断控次生油气藏成藏模式。在此基础上,通过对烃源岩、储集层、盖层、圈闭条件的研究,指出乌尔禾油田—夏子街油田—玛北油田接合部PJ地层油气藏为下一步勘探方向。

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.
