摘　　要：从区域沉积背案出发，在系统收集和整理姬塬长6油层资料的基础上，利用大量的分析化验资料，对长6储层岩石学、成岩作用、孔喉结构、渗流特征及物性特征进行详细研究，结合探井、评价井的试油试采数据及以往的开发数据，采用“多因素分析法”对储层进行综合评价，筛选出有利评价目标区。Proceeding from the regional sedimentary background, the petrological, diagenetic, pore-throat structures, percolation characteristics, and physical properties of Chang6 reservoirs have been studied in detail, on the basis of the systematic collection and sorting-out of information of Chang6 oil reservoirs in Jiyuan district of Ordos Basin, and a large amount of analysis data. Combined with the data of testing for oil or production test on exploratory and appraisal wells and from the previous development data, comprehensive evaluation of reservoirs has t^en conducted by the use of ＂multi-factor analysis method＂. Thus favorable evaluation target areas are selected.
