Due to the relatively long time interval between the completion of mining and the flooding of bottom water, the identification of oil-water layer is difficult due to the same nature of formation crude oil, so the interpretation of oil layer is very challenging. In this paper, the boundary oil, injection oil and bottom oil propellants of each oil layer in the study area, as well as the oil source and inflow direction of the oil layer, are summarized by using computer aided technology according to the geological characteristics of the block and the characteristics of permeability and oil recovery. The resistivity of water injection, oil flooding at the side and the bottom decreased obviously. Secondly, the typical reservoir of the new well is determined by comparing the logging data of the same layer between the old well and the new well and combining with the production dynamic test results of the adjacent old well. The logging response characteristics of the reservoir are analyzed, and the sensitive parameters such as deep lateral resistivity, shallow lateral resistivity, deep lateral resistivity amplitude difference, deep lateral resistivity, flush resistivity amplitude difference are optimized.
