Abstract: How to know the distribution of the property of planar or studied distribution of micro-pore structure in plane or three-dimensional space is an urgent problem in reservoir research.Fully using a great amount of well-log information to characterize these parameters is a newand effective way in studying the spatial distribution of micropore structure parameters.Through the core analysis of a key well and by various mathematical statistical methods,aninterpretation model has been established to acquire micropore structure parameters bymeans of well-logging.Then it is applied to interpret the micropore structure parameters of E_s1,E_s2,and E_s31 in Lengdong-Leijia region.Then the interpretation results were extended tospace by use of geostatistical rnethod.The results show that this method can effectivelv im-prove the accuracv of reservoir evaluation effectively.

摘要： 微观孔隙结构特征在平面乃至三维空间的分布是储层研究急需解决的问题;充分利用大量的测井信息表征这些参数,是研究微观孔隙结构参数空间分布的一个新的有效的途径.从关键井岩心分析出发,利用各种数理统计方法,建立了一套测井信息求解微观孔隙结构参数的解释模型,并对冷东-雷家地区沙一、二段及沙三段的微观孔隙结构参数进行解释,通过地质统计学方法将解释成果展布到空间中去,应用效果表明,该方法能有效地提高储层评价的精度.
