摘　　要：伊通盆地梁家～五星构造带存在有效烃源岩、优质储层、良好盖层及有利的圈闭和保存条件,因而具备优越的油气成藏条件。通过地层回剥技术恢复烃源岩的生烃史,可知双阳组、奢岭组和永吉组烃源岩进入生烃门限和大量排烃的时间不同,因此所产出的流体性质存在差异。利用盐水包裹体的均一温度,沉积埋藏史及热史综合研究,确定工区油气经历了二期的充注与成藏过程,建立了油气的成藏模式。油气成藏遵循:"切源断层控制油气的输导;储层质量控制油气的充注;构造和砂体控制油气的分布;烃源岩成熟度决定油气藏的类型"的规律。The Liangjia-Wuxing structural belt has superior oil-gas migration and accumulation conditions,including effective source rocks,quality reservoir rock,favorable cover,trap and preservation.Recovering hydrocarbon-generating history of source rock by formation back stripping technique,it is concluded that Shuangyang formation,Sheling formation and Yongjie formation have different time of hydrocarbon to reach threshold and begin to generate and expulsion abundantly,therefore the generated fluid property is different from each other as well.According to comprehensive research about homogenization temperature of brinish inclusion,depositional and burial history and thermal history,it is identified that the hydrocarbon of study area experiences injection and accumulation twice,and the oil-gas migration and accumulation pattern is also established.The law that oil-gas migration and accumulation followed is as follows:the fault which cut off source rocks control the transporting of oil-gas;the reservoir quality control the injection of oil-gas;the structure and sand body control the distribution of oil-gas;the maturity of source rock determine the type of oil-gas pool.
