摘　　要：阵列感应测井具有纵向高分辨率、深探测深度的特点,能较好地反映薄层的电阻率特征,精准识别薄储层,准确判断薄油层。塔里木盆地温宿凸起新近系吉迪克组砂岩储层物性好,油层孔隙度22%～28%,渗透率60～210 mD,属中-高孔中渗储层,原油密度0.903 8 g/cm^3,黏度38.76 mPa·s (50℃),属常规稀油,但其横向变化大且厚度较薄。本文针对新温地1井、2井砂岩储层薄难以识别的特点,在储层地质特征和常规测井分析的基础上,利用高分辨率阵列感应测井从不同纵向分辨率的电阻率曲线识别薄层,并对砂体侵入特征和储层渗透性分析,评价储层含油气性。通过高分辨率阵列感应测井技术大幅提高了该两口井的薄储层识别精度,有效评价了研究区的砂岩储层以及含油气性,指导了试油选层工作,取得了良好的效果。Array induction logging has the characteristics of high resolution and deep exploration depth,which can better reflect the features of thin layer resistivity,accurately identify thin reservoirs and precisely judge thin oil layers.The sandstone reservoir of the Neogene Wensu Uplift in the Tarim Basin has good physical properties,the porosity of the oil layer is 22%~28%,and the permeability is 60~210 mD,suggesting the medium high porosity and medium permeability reservoir,density of crude oil is 0.903 8 g/cm3,viscosity is 38.76 mPa·s(50℃),it belongs to conventional thin oil,but its lateral variation is large and the thickness is relatively small.According to the XWD 1 well,2 well thin sandstone reservoir is difficult to identify,on the basis of reservoir geological characteristics and conventional logging analysis,the authors used high resolution array induction logging to identify thin layers from different vertical resolution resistivity curves,and to analysis sand intrusion characteristics and reservoir permeability,evaluated reservoir oil-bearing property.The high resolution array induction logging technology has greatly improved the accuracy of the identification of thin reservoir in the two wells,effectively evaluated the sandstone reservoir and oil-bearing property in the study area,and guided the work of oil test layer selection,thus achieving good results.
