Abstract:Guanjiapu beach area is located in slope zone that is transient zone from Qikou sag of Bohai Bay basin to Chengning uplift, where the Es is one of major exploration strata in the area. The Es is mainly lake basin margin facies deposition and developed near-shore underwater fans. Taking the coastline as a boundary,the Es sedimentary system in the area can be divided into following parts:the east sea area is underwater fans deposition with high content of feldspar and igneous grains; the west continent is underwater fans deposition with high content of carbonate grains. The east fans are characteristic of good reservoir quality and the west are bad. The paper finely described the spatial spreading feature of fans by identification of seismic facies, seismic attributes prediction, logging-constrained inversion,micro-facies analysis, and frequency-division interpretation etc. It considered in combination with the analysis of reservoir-formed conditions that the near-shore underwater fans have the condition forming structural-lithologic reservoir and lithologic reservoir, the distribution of reservoirs has obviously controlling role to oil/gas accumulation and the favorable zones of expanded exploration areas should be along the main water channel where the fans were formed
