5700成像测井资料油水层识别关键参数研究

Study on identification of oil and water formation by the key parameters from 5700 image logging data

文章介绍了5700成像测井中核磁测井评价油水层的关键参数提取方法,并讨论了该方法的理论基础,通过利用正交偶极子声波测井测量的波列信息(纵波、横波和斯通利波)结合试验分析资料判断储层的流体性质方法的讨论,确定了正交偶极子测井计算含水饱和度的方法,为利用正交偶极子测井确定储层油水性质提供了依据。

The paper shows how to get the key factor of the nucleus magnetic resonance logging,and the basic theory that how to use the key factor to identify the oil or water reservoir is also discussed.The information of the wave from cross-dipole acoustic tool which includes the compressional,share and stoneley wave is also analysed in the paper.How to use these information to justify the formation fluid type is shown also with the experiment data about the character of the waves.The method of the water saturation from the cross-dipole acoustic data has been studied,which is the base for interpreting formation fluid type by the cross-dipole acoustic logging data.
