疏松砂岩油藏剩余油测井评价

Log evaluation on the remaining oil in loose sandstone reservoir.

在总结孤东油田水淹层特征的基础上 ,提出了利用常规测井资料评价疏松砂岩油藏剩余油饱和度的方法。通过对不同开发时期的测井资料进行解释 ,总结出剩余油在平面上和纵向上的分布规律 。

A method of evaluating the remaining oil saturation in loose sandstone reservoir using the log information is put forward based on the feature of the watered out zones in Gudong oilfield. The planar and longitudinal distribution rule of the remaining oil is summed up by the interpretation of the log information in various development period, and it provides foundation for tapping potential of the remaining oil in this oilfield.
