Abstract: Donghe sandstone reservoir in Hadeson oilfield is a massive sandstone reservoir with interlayers and edge?bottom water. Horizontal well is the main recovery process integrated with vertical well. Depletion process is adopted in pure oil zone and transitional zone during the preliminary stage, followed by combined process of depletion with artificial water injection. In view of preliminary?stage high production, low water cut, and mid?to late?stage high water cut and rapid production decline in this reservoir, this paper conducted the comparative analysis of the water drive characteristic and the production performance, showing that Type?D water drive characteristic is more suitable for the reservoir, and using Type?D curve to calculate the development indexes such as production rate, water cut, recoverable reserves, etc. can give high forecast precision of them, which have provided a reliable basis for exploitation effect evaluation, adjustment scheme compilation and development planning
