摘要
本文根据1918块样品的化验分析资料,对446井区白碱滩组油藏的岩性、孔隙结构及有关储量计算参数进行了研究;对次生孔隙的形成机理进行了初步探讨;应用综合评价指标REI值对储层进行了分类、评价。通过多元线性回归分析,建立了用多种测井信息划分、评价储层的数学模型。实践证明,该模型对识别低电阻的岩屑砂岩储层有明显的效果。
According to experimental analysis data of a total of 1918 samples from Baijiantan formation in 446 well area, a study of lithology, porous structure and parameters in connection with reserve estimates was made in this paper. Forming mechanism of secondary pore system was discussed. The classification and evaluation of reservoirs depend on the reservoir evaluation index(REI). By using multivariate linear regression analysis, the mathematical model to classify and evaluate reservoir with well logging data was established. It is proved that the model is of higher resolving power for identification of low resistivity of sand—detritus reservoir.
