Abstract：During the exploration studies for Neogene in "Three Harbours " junction area,some problems were found out,such as not enough information,only a few oil wells and low cognition for the area.In order to solve the problems,based on thought study of existing information and datasets,recognition of Neogene exploration in "Three Harbours" junction area was proposed,then more data and information were supplemented,geological structures and reservoir characteristics were carefully studied,and new cognition were obtained.With the Recognition and studies,the structure characteristic is concluded for the Neogene in "Three Harbours" junction area as the following:the structure is a reverse drag anticline controlled by Harbour-west fault,the reservoirs are rich within the structure,similar to the Harbour-east oilfield,it could be a good structure for oil to deposit.We have a whole plan first for the exploration studies in the area,then we carried out it step by step,there have been new reservoirs being found out and at last new reserve was secured in this area.
