摘　　要：通过对岩心分析、试油以及地质、地球物理测井等资料的研究,应用含油产状法、经验统计法、压汞参数法、测井参数法确定了鄂尔多斯盆地上畛子地区长6储层的厚度下限。结果表明:上畛子地区长6储层岩性下限为细砂岩,含油性下限为油迹;物性下限:孔隙度为7%,渗透率为0.1×10^(-3)μm^2;电性下限电阻率为20Ω·m,声波时差为220μs/m,含水饱和度下限为60%。Through the research on coring analysis,testing data,geological and geophysical well logging data,with the application oil-bearing occurrence,experience statistics and mercury injection parameters method,the lower limit of Chang-6 reservoir in Shangzhenzi area was determined.The research results indicate the lower limit of the lithology in Chang-6 reservoir belong to fine sandstone,lower limit of oil-bearing is oil stains,lower limit of porosity is 7%,lower limit of permeability is 0.1×10^(-3)μm^2,lower limit ofresistivity is 20Ω·m,lower limit of acoustic travel time is 220μs/m and lower limit of water saturation is 60%.
