页岩油是指赋存于生油层系、未经过大规模长距离运移的液态烃.陆相页岩油是现阶段油气勘探的热点,其储层的岩性、物性、含油性等测井特征与常规油气储层相比有着明显的差异,常规测井技术以及解释评价方法在陆相页岩油储层评价过程中存在明显不足.针对陆相页岩油储层特征及测井评价难点,优选测井新技术,如岩性扫描测井、新一代核磁共振测井、全井眼地层微电阻率成像测井,结合岩心刻度测井,实现陆相页岩油储层地质参数的计算.新疆油田玛北风城组为典型的陆相页岩油储层,利用测井新技术在研究区X1井的应用,实现储层关键参数的计算,取得较好效果.

The detection depth of borehole electrical imaging logging is shallow,so it is hard to determine whether the fractures observed on the image developed away from the wellbore.The fracture strike identified by electrical imaging logging was integrated with the shear wave anisotropy orientation measured by Sonic Scanner logging to carry out modeling.The anisotropy caused by fractures in reservoir and the extension of the fractures in the borehole were determined,and then the effectiveness of fractures was evaluated.This methodology was successfully applied in effectiveness evaluation of fracture-vug carbonate reservoir of Sinian Dengying Formation in Sichuan Basin.The combination of Sonic Scanner logging and electrical imaging logging can accurately evaluate the fracture effectiveness around the wellbore,and it provides a reliable basis for reservoir evaluation and optimization of test interval.
