孔隙度参数测井解释模型细化研究

DETAILED STUDY ON THE WELL LOGGING INTERPRETATION MODELS OF POROSITY PARAMETER

基于大庆油田萨中开发区葡一组沉积特征，充分利用测井资料和密闭取心井资料，采用多元线性回归分析等数学方法，建立了三角洲内前缘相、泛滥平原相曲流河、分流平原相的孔隙度模型。模型精度达到生产井测井解释标准及地质储量规范的计算要求，使三维地质建模能够更加精确地描述葡一组储层非均质性，为进一步挖掘厚油层内部剩余油奠定了基础。

On the basis of the sedimentary ch^acteristics of P1 Formation in Sazhong development block of Daqing Oilfield, and making full use Of the data of well logging and closed coring well, the porosity models of inner front facies of the delta, meandering facies of flooded plain facies and distributary plain facies are established by means of the mathmetical methods such as multiple regression analysis and so on. The models＇ precisions are all up to the standard of production well logging interpretation and the calculation requirements of geological reserves regulations, thus the 3D geological modeling can more accurately characterize the heterogeneity of P1 Formation reservoirs, and furthermore it has laid foundation for the further tapping of inner remained oil in those thick reservoirs.
