摘　　要：双河油田位于泌阳凹陷南缘陡坡带与深凹区过渡带逆牵引构造背景下的砂岩上倾尖灭区,砂岩上倾尖灭油藏是重要的油藏类型,其石油地质储量约占泌阳凹陷总储量的60%以上。为了探讨双河油田油水分布差异性,以单砂层为研究单元,分析渗透性差异对油水分布规律的影响,结果表明高渗透性储层有利于油气聚集,低渗透性储层不利于油气聚集。Shuanghe oilfield is located in the updip wedge-out area of sandstone under the reverse drag structure background of the southern steep slope zone and deep depression of Biyang depression.The updip wedge-out reservoir is an important reservoir type,and its petroleum geological reserves account for more than 60%of the total reserves of Biyang depression.In order to discuss the difference of oil-water distribution in Shuanghe oilfield,the influence of permeability difference on oil and water distribution is analyzed by taking single sand layer as research unit.The results show that high permeability reservoir is favorable to oil and gas accumulation,while low permeability reservoir is unfavorable to oil and gas accumulation.
