【摘要】 从油气的来源、油气运移方式和盖层分布、断裂系统的发育特征、储集相带的类型四个方面 ,对马厂构造成藏的主控因素进行了系统分析 ,总结油气成藏规律 ,指出顶部地垒带气源条件优越 ,发育三套储集层系 ,是寻找成气藏的主要场所 ;中部断层阶带沙四段具有接受油型气和煤成气两套气源的有利构造位置 ,易形成混源气藏 ;构造翼部斜坡带油藏顺反向断块呈牙刷式分布 ,是现阶段增储的有利地区。更多还原

【Abstract】 According to hydrocarbon source,mode of hydrocarbon migration and caprock distribution,fault system growth character,type of reservioir faces,this paper analyzes the major controlling factors of reservoir formation and oil gas reservoil formation law in Machang area.It is known that the prospective area for coal gas exploration is the horst belt because of good hydrocarbon source and three kinds of reservoirst,It is easy to form mixed gas reservoir in Sha-4 member of the step-faulted belt because of the structure site is prone to accumulate oil and coal gases.The en-echelon faulted blocks in the slope will be the prolific area to increase the reserves in the future exploration.更多还原
