测井新技术在梨树凹地区油水层评价中的应用

利用岩心分析资料建立了孔隙度、渗透率和饱和度模型,根据泌阳凹陷梨树凹地区试油资料、录井资料,结合核磁、高分辨率感应和偶极子声波测井新技术,建立了利用阵列感应径向侵入特征定性识别油水层方法;根据核磁测井T2谱的差谱和移谱建立了核磁测井定性、定量评价标准;利用交叉偶极子纵横波重叠法识别油水层的方法。综合上述测井新技术方法,建立了适合梨树凹地区测井评价标准,为梨树凹地区后期开发、油水层的评价,提供了坚实的物质基础。

Application of new well logging technology in oil and water layers evaluation in Lishuwa area

By using core analysis data,to establish porosity,permeability and saturation models.According to formation testing data and mud logging data,combined with magnetic resonance imaging,high resolution induction and dipole acoustic logging technologies,qualitative identification method of oil and water layer has been established with the consideration of the array induction radial invasion characteristics.According to DSM and SSM dates to establish nuclear magnetic logging qualitative and quantitative evaluation standard.By using cross dipole vertical and horizontal wave superposition method to identify oil and water layer.Based on comprehensive new well logging technology mentioned above,logging evaluation standard suitable for Lishuwa area has been established,which provides a solid material foundation for late development and oil/water layer evaluation in Lishuwa area.
