Abstract: During the high water一cut later stage, the main parame-ters have changed very greatly such as underground oil state and permeability etc, and it was not only concerned with the appraisal index of oil reservoir store layer and developed level ,but also the choice of the developing way and the adjustment direction in the future were determined. Thus , Henan oilEield successively
introduced the new logging technology such as the remaining oil saturation-RMT, PND-S, boron neutron life-span logging. It owns the different style for evaluating and describing the rich oil area and layer segment in different oil reservoirs when it was used in monitor scene and at the same time it provided the technical support for measure of increasing oil，production stabiliza-
lion and water cut controlling in oilfield.

Key words: oil reservoir evaluation, development evaluation, remaining oil saturation, monitoring
