摘要: 采用“岩心刻度测井”法,在储层四性特征与四性关系研究的基础上,对南阳凹陷东庄-北马庄核二2-3段低渗储层岩性、物性参数测井解释模型的建立进行了研究,误差分析表明,模型精度较高。高精度的岩性、物性参数测井解释模型的建立,为测井资料数字二次处理及储层非均质性研究奠定了基础。Abstract: Based on study of reservoir lithology, poroperm characteristics, electric properties and oil - bearing properties and their relationships, logging interpretation models for lithology and poroperm parameters of the lower permeability reservoirs in the second member of Hetaoyuan Fm in Dongzhuang - Beimazhuang area of Nanyang depression are built by using " core calibrating log" method. Error analysis shows that the accuracies of these models are high. These models provide a basis for secondary processing of digital logging data and study of reservoir heterogeneities.
