Abstract: Based on the development of oilfield,the reservoir geophysics techniques is necessary to accurately recognize and predict some geology features in the oilfields with high water cut,including minor fault,microstructure,frontier of sand body,lithologic barrier (abandoned channel).Those geologic features have important shelter effect on enrichment of residual oil along the horizontal direction.The thickness of sand body and property of reservoir are the factors for controlling abundance of residual oil along the vertical direction.The reservoir geophysics techniques are proposed to enhance the prediction accuracy of channel edge and the thickness of single sand body to meet the requirement for development of oilfield with high water cut.Taking the first block of East-1 District in Dagang Oilfield as an example,it is proved to be necessary and effective for developing these techniques.

Key words: oilfield with high water cut, reservoir property parameter, residual oil prediction, prediction precision, reservoir geophysics techniques
