Abstract: Sa、Pu、Gao formations of Xingbei area in Daqing Oil Field feature thin alternating beds of sand and clay in an onshore river and river delta complex. Each well in this area encountered a lot of layers. Not only the thickness and permeability between and in layers differ hundreds of times,there are also large differences in the development of various layers. Combined with the adjustment of pay zone and infill of well pattern, using plenty of logging data,detailed description of reservoir and thorough study of residual oil have been carried out since "The Eighth-Five Plan".A series of techniques of detail description on multi-well-reservoir of high water-cut period have been gradually developed. The application of these new techniques of adjustment oil field development achieved remarkable results.

Key words: high water-cut period, detailed, reservoir description, technique, adjustment and seeking out potential, application
