为利用油气田勘探中取得的大量岩心和岩屑所蕴含的地质信息,以辽河油田大民屯凹陷静西陡坡带沙河街组储层为磁性研究对象,利用1口井的数据建立了碎屑岩磁化率与总孔隙度、有效孔隙度、泥质含量间的相关模型,对7口井的磁化率与重砂分析资料进行了对比,提出了磁化率越高储层性质越好的认识。基于这个认识,对取自8口井的1009件碎屑岩磁性样品进行了分析,对碎屑岩储层性质进行了岩石磁学描述。

The geological information in the magnanimity lithoclast from the oil field exploration will be used in oil and gas well development. Rock magnetism by studied lithoclast applies to describe reservoir in Li-aohe Oil Field. A relationship between clastic magnetic susceptibility and panning data has studied in Liaohe Oil Field and found the better reservoir appears with higher magnetic susceptibility. Magnetic susceptibility datum of 1009 samples from 8 well detritus analyzed and reservoir model provided in profile and plan.
