苏北盆地阜二段泥页岩储层测井解释

LOGGING DATA INTERPRETATION OF THE MUDDY RESERVOIR IN E_1f_2 OF SUBEI BASIN

利用测井数据、岩心观察、铸体薄片、扫描电镜、三轴应力测试、全岩分析测试、有机地化测试等资料,在完成测井曲线标准化的基础上优选出影响研究区泥页岩储层质量的几个主要参数,分别建立了有机碳及无机矿物含量测井解释模型、孔隙度模型、弹性参数模型等,并基于相关模型将各参数归一化到同一岩石体积模型中,完成对单井的综合解释。结果表明:所建模型具有较高的准确性,依据测井解释结果能够有效划分出有利岩相段及易压裂层段,继而实现对苏北盆地阜二段泥页岩储层特征及可压裂性的研究,用于指导下一步泥页岩油气勘探。

Integrated interpretation is made for the data of logging,core observation,casting thin section examination,SEM analysis,triaxial shear test,bulk rock analysis and organic geochemistry.After pre-processing and standardization of logging data,some key parameters that affect the quality of the shale reservoir in E1f2 of the Subei Basin are extracted.Upon the basis,four basic models related to organic carbon,inorganic minerals,porosity and elastic parameters respectively are established.All the results after normalization are put into the physical model of bulk-volume rock for interpretation of target well.The research results prove that the above models are effective in the Subei Basin.Both favorable lithofacies and fracturing layers can be predicted via compressive interpretation of logging data.The research results may have some significance for reservoir evaluation and fracture prediction in the E1f2 of the Subei Basin.
