This paper introduces the performance history of the Daqing Oilfield and analyzes the potential for further development.

The residual oil distribution characteristics are analyzed taking the advantage of the core data of Well La8-JP182 and Well Bei1-330-J49. Then the numerical simulation method is used to analyze the recovery ratio, production rate, and the variation of pressure gradient under different production conditions. Finally, the technology of potential tapping of the isolated untabulated reservoirs, tabulated reservoirs, the huge thick reservoirs, and multiple rhythm reservoirs are brought forward in this paper.
